1. Outer planets are gaseous planets (Jovian Planets). All the outer planets have ring system. They have many number of natural satellites. They have longer period of revolution as compared to inner planets.
2. Outer planets are different from each other in the following way:
The size and mass of the four outer planets is different from each other. Uranus rotates in opposite direction as compared to rest of the planets. Jupiter is the largest planet where as Saturn is the lightest. All the outer planets have different composition of gases and water.
3. Dwarf planets are smaller in size and have irregular shape as compared to true planets. In our solar system, we have 8 true planets and 5 official dwarf planets but can be as many as 10,000 dwarf planets present in Kuiper belt.
4. The outer planets lie beyond asteroid belt in the following sequence: Jupiter, Saturn, Uranus and Neptune. Due to this arrangement, as the distance increases from the Sun, the temperature of the surface of these planets drops.
6. Titan is the largest moon of Saturn. Scientists are interested in studying Titan because of its dense atmosphere and liquid hydrocarbons lakes. Methane lakes are present on its surface. Although there is no water on it but scientists are exploring the possibility of life sustained on hydrocarbons as there is presence of pre-biotic environment with the possibility of biotic environment in sub-surface. It has methane cycle like water cycle on Earth and weather pattern.
Outer planets are similar in composition and have multiple moons and rings but differ in size, atmospheric composition, and structure of moons and rings. Dwarf planets haven't cleared their orbits. The arrangement of outer planets is influenced by gravitational pulls. Titan, Saturn's largest moon, interests scientists due to its Earth-like features.
Explanation:The outer planets, also known as the gas giants, are similar to each other in that they are composed primarily of gases, like hydrogen and helium, and they all have ring systems and multiple moons. Outer planets include Jupiter, Saturn, Uranus, and Neptune. However, they are different in terms of size, composition of their atmospheres, number and structure of their rings and moons.
Dwarf planets are different from true planets in various aspects. Dwarf planets like Pluto, fail to meet the third criteria in the planet definition which is clearing its orbit. This means there are other bodies of comparable size other than its own satellites in its orbit in space.
The arrangement of outer planets greatly affects their placement as they follow elliptical paths which are affected by the gravitational pull of the Sun and other planets. For instance, the position of Jupiter greatly affects the positions of other outer planets.
Titan is Saturn's largest moon and it is of special interest to scientists due its Earth-like features such as presence of liquid lakes and rains, except that they're made of methane, not water, and its dense atmosphere.

what is the measurement of how fast an object moves relative to a reference point?
The measurement of how fast an object moves relative to a reference point is speed, or motion. Hope this helped:)
Final answer:
The measurement of an object's speed relative to a reference point is termed relative speed, which all observers can agree upon when accounting for distance and elapsed time. High-speed measurements can vary due to relativistic effects such as length contraction. Velocity includes both speed and direction of motion.
Explanation:
The measurement of how fast an object moves relative to a reference point is known as relative speed. This concept is crucial because the measurement of speed depends on the observer's frame of reference. When determining the relative speed of an object, both the distance the object travels and the time it takes to cover that distance are taken into consideration. The equation for relative speed is the distance traveled divided by the elapsed time, which all observers can agree upon, regardless of their individual motion.
Another important factor to consider at high speeds, especially those approaching the speed of light, is how these measurements can differ due to relativistic effects. According to the theory of relativity, as described by the equation 1 - v²/c², an observer at rest would perceive the length of an object moving at speeds close to the speed of light as significantly shortened. This length contraction affects how distances and, consequently, speeds are measured.
In the context of everyday speeds, we often discuss velocity, which is the speed of an object with the direction of its motion considered. If an object is said to have a speed of 50 mph, that's its scalar magnitude. However, if that object is moving northeast at 50 mph, its velocity is defined, combining both magnitude and direction.
if a car engine does 600,000 J of work over a 500m distance and the mass of the car is 250Kg then what is the final velocity of the car?
Given that
Work = 600,000 J ,
distance(S) = 500 m ,
mass (m) = 250 Kg ,
Determine the velocity of car (v) = ?
We know that,
Work = Force × distance
=> Force = Work ÷ distance
= 600,000 ÷ 500
= 500 N .
Also Force F = m.a ; from Newtons II law
500 = 250 × a
a = 2 m/s.
Final Velocity from the given formula
V² = u² + 2.a.s
= 0 + 2 × 2 × 500
= \sqrt{2000}
v = 44.7 m/s
A 10n force is applied to a 25kg mass to slide it across a frictional surface. What is the acceleration of the mass?
Force (in Newtons) equals mass (in kilograms) times acceleration (in meters per second squared).
Plug in the given force and mass to the equation and solve for acceleration:
10=25a
0.4m/s2=a
Hope this helps!!
Answer: a = 0.4m/s^2 - 9.8*c where c is the coefficient of kinetic friction of the surface
Explanation: We know that, by the second Newton's law, a = F/m
where a is the acceleration, F is the net force and m is the mass of the object.
Then, if the surface is frictionless, the total force applied in the object is 10N, and the mass of the object is 25kg, so the acceleration is:
a =10N/25kg = 0.4m/s^2.
But if the surface is frictional, there will be a force of friction applied in the mass (this depends on the coefficient of friction and the weight of the mass), this means that the acceleration will be reduced.
If = -(9.8*25)*c
where c is a number that is bigger than 0 and smaller than 1, is called the coefficient of kinetic friction.
So the total force is now:
F = (10 - 9.8*25*c)
Then, the acceleration in a frictional surface is equal to:
a = (10 - 9.8*25*c)/25 = 0.4m/s^2 - 9.8*c
A centrifuge was used to separate into it’s components. What conclusions out the sample can be formed based on the technique used?
A centrifuge is used to separate specimens of different densities. It applies a centripetal force to cause the denser components to separate from the less dense ones. This technique can be used for various purposes, including cell fractionation and separating bacteria, viruses, and proteins based on their density.
Explanation:A centrifuge is a rotating device used to separate specimens of different densities. It operates by applying a centripetal force, which causes the denser components to separate from the less dense components. Based on the technique used, one can conclude that the sample was separated into its components based on differences in density.
For example, in the case of cell fractionation, a centrifuge can be used to separate subcellular structures by differences in mass. The more massive structures settle at the bottom of the centrifuge tube first, while the less massive ones remain suspended for longer. This allows for the isolation and analysis of different organelles and cellular substructures to determine their functions.
In other applications, such as in the separation of bacteria, viruses, and proteins, a centrifuge can separate these components based on their density. The heavier components settle at the bottom while the lighter ones remain suspended. This enables the isolation and study of these components individually.

Satellite A orbits the earth at a height 2.00 times the earth's radius.Satellite B orbits the earth at a height 3.00 times the earth's radiusWhat is the ratio of the period of Satellite B to the period of Satellite A?
Answer:[tex]\sqrt 3 :\sqrt 2[/tex]
From Kepler's law: The cube of radius of the orbit of satellite is proportional to square of time period of orbit.
[tex]r^3=\frac{T^2 Gm}{4\pi ^2}[/tex]
where, r is the radius of the orbit of satellite, T is the time period of satellite, G is the gravitational constant, m is the mass of the planet.
R is the radius of Earth.
[tex]\frac{r_A^3}{r_B^3} = \frac{T_A^2}{T_B^2} \\ \Rightarrow \frac{2R}{3R}=\frac{T_A^2}{T_B^2} \Rightarrow \frac{T_B}{T_A}=\sqrt{\frac{3}{2}} [/tex]
Hence, the ratio of the period of Satellite B to the period of Satellite A is [tex]\sqrt 3 :\sqrt 2[/tex]
Final answer:
The ratio of the period of Satellite B to the period of Satellite A is approximately 1.89.
Explanation:
In order to calculate the ratio of the periods of Satellite B to Satellite A, we need to understand that the period of a satellite is related to the radius of its orbit. According to Kepler's third law, the square of the period of a satellite is directly proportional to the cube of the radius of its orbit.
Let's define the radius of Earth as R and the radius of Satellite A's orbit as RA. From the given information, RA = 2R and the radius of Satellite B's orbit as RB = 3R.
The ratio of the periods can be expressed as:
(TB/TA)² = (RB/RA)³
Substituting the values, we get:
(TB/TA)² = (3/2)³ = 27/8
Taking the square root of both sides, we find:
TB/TA = [tex]\sqrt{(27/8)}[/tex] ≈ 1.89

the resistor has a resistance of 3 ohms. If no change in the battery size occurs, what will happen to the current if the resistance increases to 6 ohms?
Quick answer the current will go down.
The formula is
E = I * R. The variation is a direct one. Let us suppose E = 12 volts.
12 = I * 3 ohms Divide both sides by 3
12/3 = I
I = 4 amps
Now do it again for 6 ohms
12 = I * 6 Divide both sides by 6
12/6 = I
I = 2
So the current went down from 4 to 2

A 50kg Cheetah has a kinetic energy of 18,000J. What is its velocity?
The velocity of a 50kg cheetah with a kinetic energy of 18,000 J is approximately 26.83 m/s, calculated using the formula for kinetic energy = 1/2 * m * v^2.
Explanation:The question concerns the relationship between the kinetic energy, mass, and velocity of an object, specifically a 50kg cheetah. Kinetic Energy is given by the formula 1/2 * m * v^2, where m is the mass and v is the velocity. Specifically, in this scenario, the kinetic energy of 18,000 J (Joules) equals 1/2 * 50 kg * v^2 . Solving this equation for velocity, we have v = sqrt((2 * Kinetic Energy) / m) = sqrt((2 * 18000) / 50) = sqrt(720) ≈ 26.83 m/s.

(i) Time taken by the car to acquire the velocity of 40m/sec. (ii) Distance travelled by the car for attaining the velocity of 40m/sec.
Final answer:
The time taken by the car to reach a final velocity of 40 m/s is 5 seconds, and the distance traveled by the car during this acceleration is 150 meters.
Explanation:
To solve this physics problem, we need to use the equations of motion. Specifically, we're looking for the time (i) Time taken to reach a final velocity and the (ii) Distance traveled during this acceleration.
Calculating the Time Taken (i)
The equation to use here is v = u + at, where:
v is the final velocity (40 m/s)u is the initial velocity (20 m/s)a is the acceleration (4 m/s²)t is the time (which we are trying to find)Substituting the known values we get:
40 = 20 + 4t
t = (40 - 20) / 4
t = 5 seconds
Calculating the Distance Travelled (ii)
Now we use the equation x = ut + ½ at² to find the distance traveled, where x is the distance. With the time (t = 5s) calculated from the previous part, we get:
x = 20 × 5 + ½ × 4 × 5²
x = 100 + 50
x = 150 meters
What happens when two forces act in the same direction?
When two forces act in the same direction, they add together. ... Equal forces acting in opposite directions are called balanced forces. Balanced forces acting on an object will not change the object's motion. When you add equal forces in opposite direction, the net force is zero.
When two forces act in the same direction, their magnitudes add up to create a larger force. This results in the object moving in the direction of the resulting force with increased acceleration.
Explanation:When two forces act in the same direction, they combine or add up to create a larger force. This is known as the principle of superposition of forces. An example of this can be seen when two people push the same object in the same direction; the force exerted by the object will be the sum of the two individual forces. The object will move in the direction of the resulting force, and its acceleration will be greater than when acted on by a single force.
