Potential energy is stored energy. Bodies have potential energy by virtue of their position, their condition or state. On the other hand, kinetic energy is energy possessed by an object or body in motion.
It is called the absorber. When you think of this think of wearing a black shirt in the sun light. It absorbes all the sun light (waves) when it hits it. Hope this helps you.
Its average speed, pretending that it traveled at a constant speed, is
v = s / t
= 600 m
5 x 60 s
= 2 m/s
but to be a velocity it needs a direction as well as a speed.
( Sorry. Can’t find a division line to put between the 600 m and the 5 x 60 s )
As an object accelerates i.e., change it's velocity(either direction or speed), the position of the object depends on two factor; If the acceleration was direction based then it might have a zero displacement for eg: if it travels in circle. or it might have a net displacement if it travels in a straight line, quantitatively
where,
s = displacement
u = initial velocity
v = final velocity
a = acceleration
t = time
Now, for the hypothesis;
There is no direct relationship between fan speed and acceleration but anyways generally speaking if we do have a relationship that with more fan speed we have a larger displacement of air i.e., a more force i.e., greater acceleration
Thus, it can be said, well not exactly scientific, that with a greater fan speed there will be greater acceleration. if fan speed is increased then acceleration will be more.

Answer:
a)
b)
c)
d)
Explanation:
Given:
- length of muscle fibers,
- maximum stress on each fiber,
- Volume of muscles,
<em>∴Area of the muscle:</em>
a)
Maximum force developed by this muscle:
b)
Force when the muscles are 10% activated:
c)
- contraction in length of muscle,
- time taken for the contraction,
<u>Now, the speed of the muscle:</u>
d)
<u>Maximum force delivered when the muscle fibers are oriented at 15° from the tendons:</u>
