Force is a push or a pull of an object that causes the object to speed up, slow down, or stay in one place. In other words, a force is what causes an object to move. Friction and gravity are two types of forces that influence how an object moves.

Hope I can help you!

A push or a pull on an object is known as a force.

Option D.

<u>Explanation:</u>

For example, if we kick a ball the ball moves in the direction of the kick. Here on kicking the ball we apply a force on the ball that made the ball move. So, the motion (push/pull) of an object is due to the force applied on it.

Force is a vector quantity defined by the product mass and acceleration. That is, F=ma. The SI unit is Newton (N).

Velocity is the rate of change of speed of an object.

Acceleration of an object is the rate of change of velocity.

20 cubic inches of a gas with an absolute pressure of 5 psi is compressed until its pressure reaches 10 psi. What's the new volu

boyakko [2]

It is given that that initial volume of gas is 20 cubic inches.

The initial pressure is given as 5 psi.

The final pressure is given as 10 psi

We are asked to calculate the final volume.

Let initial and final volume of gas is denoted as $v_{1} \ and\ v_{2}$

Let the initial and final pressure of gas is denoted as $p_{1} \ and\ p_{2}$

As per the question the temperature of a gas is constant.

From Boyle's law we know that pressure of a given mass of a gas is inversely proportional to the applied volume at constant temperature.

Hence mathematically

$p\ \alpha\ \frac{1}{v}$

$pv=constant$

$p_{1} v_{1} =p_{2} v_{2}$

$v_{2} =\frac{p_{1}v_{1} }{p_{2} }$

Putting the values of these respective quantities as mentioned above we get-

$v_{2} =\frac{5\ psi*20 cubic\ inches}{10\ psi}$

$=10\ cubic\ inches$ [ans]

What travels in a wave from one location to another is _________.

Alina [70]

Answer:

Energy

Explanation:

A wave is a kind of disturbance which passes through a medium and during this process, energy is transferred from one point to another without causing any permanent displacement to the medium itself.

for example if a stone is dropped inside water, circular ripples are observed and energy moves from one point to another .
