When a gas is inside the tube, the individual air molecules travel the length of the tube.

<h3>What is molecules?</h3>

The individual particle of a gas element moving randomly inside the element structure.

When the gas contained in a container, the molecules move randomly inside it. According to the kinetic theory of gases, molecules travel the mean distance. The air molecules vibrates horizontally parallel to the length of the tube.

In an open tube, air molecules are distant from each other. So, they can travel the length of the tube.

Thus, individual air molecules travel the length of the tube.

If a Girl Bounces a Ball, At what point does the ball have velocity?

mihalych1998 [28]

An object ALWAYS has velocity, although the velocity may be zero for most of the time, or even all the time.

'Velocity' means the object's speed AND the direction in which it's moving.

As long as the girl stands and holds the ball in her hand, the ball's velocity is zero. As soon as she drops it out of her hand, it starts having velocity that's not zero.

While it's bouncing, its velocity is . . .

== growing and downward while it's falling from her hand toward the ground,

== zero for the instant of time when it hits the ground and changes direction from down to up,

== shrinking and upward while it's rising from the ground to her hand,

== zero for the instant of time when it hits her hand and changes direction from up to down.

A cellphone weighing 80 g is flying to the air at 15 m/s what is it's kinetic energy

adell [148]

Answer:

Explanation:

Given parameters:

Mass of cell phone = 80g

1000g = 1kg

80g is therefore 0.08kg

Velocity of the cellphone = 15m/s

Unknown:

Kinetic energy of the cellphone = ?

Solution:

The kinetic energy of a body is the energy due to its motion.

It is expressed as:

K.E = $\frac{1}{2}$ mv² = $\frac{1}{2}$ x 0.08 x 15² = 9J
