The same thing that holds everything else 'down' --- gravity.

Forward and downward speed are referred to as acceleration and deceleration respectively.
<h3>
What is Acceleration?</h3>
This is the rate at which an object gains speed with respect to time with its unit being meter per second square(m/s²).
Objects in constant speed are said to have a uniform motion. The downward speed is known as deceleration which involves the object losing speed to return to a state of rest.

<span>a. We can find the velocity when the camera hits the ground.
v^2 = (v0)^2 + 2ay = 0 + 2ay
v = sqrt{ 2ay }
v = sqrt{ (2)(3.7 m/s^2)(239 m) }
v = 42 m/s
The camera hits the ground with a velocity of 42 m/s
b. We can find the time it takes for the camera to hit the ground.
y = (1/2) a t^2
t^2 = 2y / a
t = sqrt{ 2y / a }
t = sqrt{ (2)(239 m) / 3.7 m/s^2 }
t = 11.4 seconds
It takes 11.4 seconds for the camera to hit the ground.</span>
The answers would be:
A. It becomes less dense
C. It expands
If you ever noticed, ice tends to float on water.Due to Hydrogen bonding, fluid is able to be displaced when water is converted into ice which causes it to be able to float after the expansion of water. <span />
