Answer;
velocity(v) = 97.2 m/s ,
distance (S) = 100 m
determine time(t) = ?
We know that,
distance (S) = velocity(v) × time(t)
So, time (t) = distance ÷ velocity
= 100 ÷ 97.2
<em> t = 1.02 sec.</em>

<span>On the surface of the Earth, the escape velocity is about 11.2 km/s, which is approximately 33 times the speed of sound (Mach 33) and several times the muzzle velocity of a rifle bullet (up to 1.7 km/s). However, at 9,000 km altitude in "space", it is slightly less than 7.1 km/s.</span>
Answer:
Chemical reactions occur slower at lower temperatures and faster at higher temperatures. When you put a glow stick in cold water, the chemical reaction slows down but will last for a longer period of time. When you put a glow stick in hot water, the reaction speeds up but will be over quicker.

Answer:
Therefore the terminal velocity = 1.45 m/s
Explanation:
Terminal velocity: Terminal velocity is the highest velocity of an object when it falls from rest trough a media.
= terminal velocity
w = weight of the object = mg
= drag coefficient=0.80
A= frontal area
= media density = 1.2 kg/m³
m = mass = 8 kg
g= acceleration due to gravity = 9.8 m/s²
Front area = length× breadth
= (18×47)cm²
=846 cm²
Therefore the terminal velocity
=1.45 m/s
Therefore the terminal velocity = 1.45 m/s
