What type of matter will determine how much inertia an object has?

Answers

The two main things are speed and velocity. you have to factor in a bunch of smaller things too, but those don't really have much of an effect. And mass inertia is the resistance of any physical object to any change in its state of motion. The velocity of an object will determine the inertia that the object has. Good luck on your assignment and have a great day! :D

Table tennis the path of a table-tennis ball after being hit and hitting the surface of the table can be modeled by the function h=-4.9t(t-0.42) where h is the height in meters above the table and t is the time in seconds. how long does it take the ball to hit the table?

Answers

We are given the equation:

h = -4.9 t (t – 0.42)

 

In this problem, to solve for the time when the ball hit the table, the height h must be equal to zero. That is, h = 0 so that:

0 = - 4.9 t (t – 0.42)

0 = (t – 0.42)

t = 0.42 seconds

Reyna kicks a ball, which then rolls across a grassy field. Which is the best explanation for why the ball eventually comes to a stop?

A. The force of gravity pulls the ball down into the grass until it can no longer move

B. The force of friction between the ball and the grass slows the ball to a stop.

C. The force from air resistance slows the ball to a stop.

D. A force is not necessary because all things naturally come to a stop.

Answers

Option B is correct:)

Sorry im so late!

Answer:

B. The force of friction between the ball and the grass slows the ball to a stop.

Explanation:

When Reyna kicks the ball the force due to contact between her foot and ball accelerate the ball and hence it starts moving on the grass

But after some time ball stops rolling on the grass. So we can conclude here that there must be some external force on the ball due to which it stops rolling on the grass.

As we know that state of motion of an object will change only when some external unbalanced force act on an object.

So here this external unbalanced force is due to grass which resist the motion of ball and it stops.

Here this resistance force is known as friction force of grass on the ball which resist the motion of ball and it stops so correct answer will be

B. The force of friction between the ball and the grass slows the ball to a stop.

- an object is thrown upwards with a speed of 16 m/s. how long does it take it to reach a height of 7.0 m on the way up?

Answers

Final answer:

Calculate the time for an object thrown upwards at 16 m/s to reach a height of 7.0 m.The time it takes the object to reach 7.0 m on the way up is approximately 1.63 seconds.

Explanation:

To find the time it takes for the object to reach a height of 7.0 m on the way up:

Identify the known quantities: Initial velocity (u) = 16 m/s, final velocity (v) = 0 m/s (at the top of its flight), acceleration (a) = -9.8 m/s² (acceleration due to gravity).

Use the kinematic equation: v = u + at and solve for time (t).

Calculate the time taken: t = (v - u) / a.

The time it takes the object to reach 7.0 m on the way up is approximately 1.63 seconds.

Answers

The correct option is SCALE.
This is because the experimental data you are interested in is mass and scale is the instrument that is used to measure mass. To use the scale, measure the mass of your water before you put it inside the sun and measure the mass again after you remove it from the sun. The difference in mass is the quantity of water that is evaporated.
 There are different type of scale and the one that you use will depend on the size of the material that you want to measure.

A tuning fork produces a sound with a frequency of 256 hz and a wavelength in air of 1.33 m. find the speed of sound in the vicinity of the fork.

Answers

Final answer:

The speed of sound in the vicinity of a tuning fork with a frequency of 256 Hz and a wavelength of 1.33 m is approximately 341.28 m/s.

Explanation:

The speed of sound can be calculated using the formula:

Speed of sound = frequency x wavelength

Given:

Frequency of the tuning fork = 256 Hz

Wavelength in air = 1.33 m

Substituting the given values, we get:

Speed of sound = 256 Hz x 1.33 m = 341.28 m/s

Therefore, the speed of sound in the vicinity of the fork is approximately 341.28 m/s.

How was the formation of the outer planets affected by their distance from the sun?

Answers

The formation of the outer planets are affected by their distance from the sun with having them to maintain the lighter elements that they are composed of such as the hydrogen and helium, having them far away will also make their planet more cooler as the sun is distant from them.

Final answer:

The formation of the outer planets, like Uranus and Neptune, was affected by their distance from the Sun as they likely formed closer to where Jupiter and Saturn are now. The low density of matter in the disk surrounding the Sun outside the orbit of Saturn made it difficult for Uranus and Neptune to form at their present distances. Computer models show that gravitational interactions with neighboring planets could have caused Uranus and Neptune to move to their current locations.

Explanation:

The formation of the outer planets, such as Uranus and Neptune, was affected by their distance from the Sun. According to astronomers, these planets likely did not form at their present distances but closer to where Jupiter and Saturn are now. This is because the density of matter in the disk around the Sun at the time of planet formation was too low outside the orbit of Saturn to build up Uranus and Neptune in a reasonable amount of time. Computer models suggest that Uranus and Neptune could have formed near Jupiter and Saturn and then moved to their current locations through gravitational interactions with their neighboring planets.

An object with a mass of 5 kg is dropped and takes 9 s to hit the ground. then another object with a mass of 10 kg is dropped from the same point. how long does it take to hit the ground

Answers

It does not matter how heavy the object is, as long as there is no drag or wind interference (such as wind on a feather or piece of paper) the gravitational pull will be equal, therefore the answer is 9s.

The time taken for an object to hit the ground is independent of its mass when air resistance is neglected. Therefore, the second object will also take 9 seconds to hit the ground.

Understanding the Effect of Mass on Free Fall

When you drop an object, its time to reach the ground is determined by the laws of physics related to free fall. Under the influence of gravity, all objects fall at the same rate regardless of their mass, assuming we are neglecting air resistance.

Given: Mass of first object, [tex]m_1 = 5 kg[/tex], Time to hit the ground, [tex]t_1 = 9 s.[/tex]

The second object has a mass, [tex]m_2 = 10 kg[/tex]. To find the time [tex]t_2[/tex] to hit the ground for the second object:

Since both objects are dropped from the same height and air resistance is neglected, the time taken [tex](t_2)[/tex] by the second object to reach the ground is not dependent on its mass and will be the same as the first object.

Thus, the second object will also take 9 seconds to hit the ground.

The acceleration due to gravity (usually denoted as g) is constant at approximately 9.8 m/s² on Earth, which means that in a vacuum, all objects fall at the same rate regardless of their mass.

This principle is often demonstrated in physics classrooms and can be counterintuitive because we see different objects fall at different speeds in everyday life due to air resistance.

If while riding in a smooth-riding train, you toss a coin upward, the coin will normally land ______.

Answers

the coin will normally land on our hand.

Final answer:

The coin will typically return to your hand.

Explanation:

When you toss the coin upward, it follows a parabolic trajectory due to the force of gravity acting on it. However, because you and the coin are moving at the same velocity and in the same direction as the train, no external horizontal forces are acting on the coin. As a result, the coin maintains its horizontal velocity relative to you throughout its motion. This means that while the coin moves vertically, its horizontal position relative to you remains unchanged. Consequently, as the coin descends, it will ultimately land back in your hand, following the same vertical path it took when tossed upward.

Compare the size of forces due to static, sliding, and rolling friction between two surfaces.

Answers

Static sliding has a much greater force then rolling friction cause it covers
Final answer:

Static friction is the greatest and occurs when two surfaces are stationary relative to each other. Sliding or kinetic friction is typically less and happens when two surfaces are sliding against each other. Rolling friction is usually the least and occurs when an object rolls over a surface.

Explanation:

When comparing the size of forces due to static, sliding, and rolling friction between two surfaces, it's important to note that different types of friction have different magnitudes. Static friction occurs when two surfaces are stationary relative to each other and it tends to be the greatest type of friction. This is due to the fact that it is overcoming the initial force that keeps an object at rest.

On the other hand, sliding friction or kinetic friction, is typically less than static friction. This type of friction happens when two surfaces are sliding against each other. As the surfaces are in motion, it's easier to maintain that motion, thus requiring less opposing force.

Lastly, rolling friction is generally the least among the three. It occurs when an object rolls over a surface, such as a wheel over a road. Because only a small portion of the object is in contact with the surface at any given time, there is less surface area creating resistance, and thus less friction. However, the actual magnitude of these forces depends on the specific materials of the two surfaces in contact and the normal force acting on the objects.
