How can 2 objects have the same temperature but different amount of thermal energy?
A student arranged the four cards sequentially in a row on the basis of the periods when these events occurred. The card showing the earliest event was placed on the extreme left. Which of these cards was placed third in the row?
An object is raised above the ground gaining a certain amount of potential energy. if the same object is raised twice as high, it gains:
If the same object is raised twice as high, it gains: double the potential energy.
Potential energy (P.E) can be defined as a type of energy possessed by an object (body) as a result of its position (height) above the earth. Thus, potential energy (P.E) is highly dependent on the height above the ground.
Mathematically, potential energy (P.E) is calculated by using the following formula:
[tex]Potential \;energy (P.E) = mgh[/tex]
Where:
m is the mass of object.g is the acceleration due to gravity.h is the height of an object.Since the height of the object is raised twice as high, it simply means the value of height (h) would be multiplied by two (2) and the potential energy (P.E) would double:
[tex]Height = 2[/tex] × [tex]height[/tex]
[tex]P.E = 2(mgh)[/tex]
In conclusion, raising the same object is raised twice as high, would cause the potential energy (P.E) to double (twice as much as the initial value).

The maximum power output of an engine is usually given in units called
Final answer:
Engine power output is typically measured in horsepower (hp), where 1 hp equals 746 watts (W). The watt is the SI unit for power, defined as 1 joule per second.
Explanation:
The maximum power output of an engine is commonly expressed in a unit known as horsepower (hp). The International System of Units (SI) for power is the watt (W), where 1 W is defined as 1 joule per second (1 J/s). However, in many applications, especially when referring to engines, power is frequently stated in horsepower. To convert horsepower to watts, recall the equivalence that 1 hp equals 746 W.
For instance, the power output of an engine might be specified as 100 hp, which translates to approximately 74.6 kilowatts (kW), since 1 kW equals to 1,000 watts.

At a given instant in time, a 6-kg rock that has been dropped from a high cliff experiences a force of air resistance of 15 n. what are the magnitude and direction of the acceleration of the rock? (do not forget the gravitational force!) round the final answer to two decimal places.
The magnitude of the acceleration of the rock is 7.3 m/s² downward.
Explanation:The rock experiences two forces at this given instant: the force of gravity and the force of air resistance. The force of gravity is equal to the weight of the rock, which is given by the equation Fg = mg, where m is the mass of the rock (6 kg) and g is the acceleration due to gravity (9.8 m/s²). Therefore, Fg = 6 kg × 9.8 m/s² = 58.8 N. The force of air resistance is given as 15 N.
To find the net force acting on the rock, we subtract the force of air resistance from the force of gravity: Fnet = Fg - Fair = 58.8 N - 15 N = 43.8 N.
The magnitude of the acceleration of the rock can be found using Newton's second law, which states that the net force on an object is equal to the mass of the object multiplied by its acceleration. Therefore, a = Fnet / m = 43.8 N / 6 kg = 7.3 m/s².
The direction of the acceleration is downward, which is the same as the direction of the force of gravity.

A softball is fouled off with a vertical velocity of 20 m/s and a horizontal velocity of 15 m/s. what is the resultant velocity of the ball
The resultant velocity of the softball fouled off with vertical and horizontal components of 20 m/s and 15 m/s, respectively, is 25 m/s, calculated using the Pythagorean theorem.
To calculate the resultant velocity of a softball that is fouled off with a vertical velocity of 20 m/s and a horizontal velocity of 15 m/s, we can use the Pythagorean theorem. The resultant velocity (Vr) is the vector sum of the vertical (Vy) and horizontal (Vx) components of velocity.
The formula for the resultant velocity is given by:
[tex]Vr = \/(Vx^2 + Vy^2)[/tex]
Plugging in the values we have:
[tex]Vr =\/(15 m/s)^2 + (20 m/s)^2Vr = \/(225 + 400) m/sVr = \/625 m/sVr = 25 m/s[/tex]
Therefore, the resultant velocity of the softball is 25 m/s.

The force of gravity is an inverse square law. this means that, if you double the distance between two large masses, the gravitational force between them __________.
If you double the distance between two large masses, the gravitational force between them decreases by a factor of four.
The law of inverse squares states that the gravitational force is inversely proportional to the square of the separation between the masses. The relationship can be described mathematically as follows:
F ∝ 1 / [tex]r^2[/tex]
where r is the distance between the masses and F is the gravitational force.
The inverse square connection causes the force to decrease to one-fourth of its initial magnitude when the distance (r) is doubled.
Thus, in other words, when the space between the masses is doubled, the gravitational force is reduced by a factor of 4.

What is the wavelength of a proton traveling at a speed of 6.21 km/s? what would be the region of the spectrum for electromagnetic radiation of this wavelength?
The wavelength of the given proton is approximately 6.01 * 10⁻¹⁴ m, and this fits into the gamma rays region of the electromagnetic spectrum. The electromagnetic spectrum ranges from gamma rays to radio waves and the proton's wavelength indicates it being of higher energy.
Explanation:The wavelength of a proton can be found using the de Broglie wavelength formula:
λ = h / (m*v),
where h is Planck's constant 6.63 * 10⁻³⁴ J*s, m is the mass of the proton and v is its speed. So first convert the speed of the proton from km/s to m/s: 6.21 km/s * 1000 = 6210 m/s.
Then substitute into the formula:
λ = 6.63 * 10⁻³⁴ J*s / (1.67 * 10⁻²⁷ kg * 6210 m/s).
After the calculation, we find that the wavelength of the proton is approximately 6.01 * 10⁻¹⁴ m.
Now, we analyze the region of the electromagnetic spectrum for electromagnetic radiation of this wavelength.
The electromagnetic spectrum ranges from gamma rays (with wavelengths shorter than 10^-11 m) to radio waves (with wavelengths longer than 10⁻¹ m).
The calculated wavelength of the proton, 6.01 * 10⁻¹⁴ m, falls into the gamma rays region of the electromagnetic spectrum and inclines towards the higher energy end.
