Suppose you now take the ball and using a bat, pop it straight up into the air with a hang-time of 5.00 s (the hang time is how

dolphi86 [110]

Answer:

Explanation:

Using the equation of motion formula $S = ut + \frac{1}{2}gt^2$ where;

S is the height to which the ball rises

u is the initial velocity of the ball = 0m/s

a is the acceleration due to gravity = 9.81m/s²

t is the time taken by the ball in air = 5.0s

Note that the time to rise to the peak is one-half the total hang-time = 5.0/2 = 2.5s

Substituting the given parameters into the formula above to get S:

$S = ut + \frac{1}{2}gt^2\\\\S = 0(2.5)+ \frac{1}{2}(9.81)(2.5)^2\\\\S = 0+\frac{1}{2}(9.81)\times 6.25 \\\\S = \frac{61.3125}{2}\\ \\S = 30.65625m\\\\S \approx 30.66m$

This means that the ball rises 30.66m before it reaches its peak.

Which of these is a measure of how much force is applied to an object from gas particle bouncing into it?

IrinaK [193]

Answer:

Pressure

Explanation:

The measure of how much force is applied to an object from gas particle bouncing into it is called pressure.

Pressure is defined as the force per unit area on a body.

Mathematically;

Pressure = $\frac{Force}{Area}$

The pressure of a gas is the combined force with which gas molecules bombard a unit area of the wall of the container. It is the sum of all tiny pushes on the wall of the container.

Various units of pressure are atm, mmHg, torr, pascal e.t.c
