Answer:

Explanation:
initial speed of the aircraft = 0
it covers a distance = 100 m
time taken by it = 53 s
so we will have



now we know that there are two forces on the aircraft
1) applied force in forward direction
2) friction force in opposite direction
so we will have




so net force by 60 officers is 53440 N
so force due to each officer is given as

Answer:
a. TRUE
Explanation:
When a satellite is launched to orbit around earth, it has to produce its own artificial gravity by performing rotations. The frequency of this rotation is given by the following formula:
f = √[ac/4πR²]
where,
f = frequency
ac = centripetal acceleration
R = Radius of the satellite
Therefore, it is clear from this formula that the frequency of rotation of the satellite is independent of its height above the surface of earth. So, the correct option is:
<u>a. TRUE</u>
There must be a centripetal force to move the object move in a curve path.
Formula from physics to get the answer.
Answer:
D: The distance between the particles decreases
Explanation:
Taking away energy slows down molecules, like how you slow down when you are cold (I think)
