a). F= m a
500 N = (m) (5.00 m/s^2)
m = 100 kg
b). Accelerating body covers distance of
D = 1/2 a T^2
D = 1/2 (5.00 m/s^2) (100 s)^2
D = 25,000 meters
Note: I'm pretty sure the acceleration is typed wrong in the question. If so, then these answers won't be correct.
To attain equilibrium there should be net force on the body, so that the object will not be in motion. so for a body of wb, any weight will do as long as there is no external force that is applied to it. the only force that is acting on it is the weight which is going down, and the normal force which is going up, to counter act the weight. and the net force is zero.
A watershed supplies water to a river system.

The magnifying power of this telescope is 12,5.
<h3>What is a telescope?</h3>
The telescope is an optical instrument that aims to allow the observation of large objects at long distances, such as galaxies, stars and planets. It consists of two parts: the objective, which can be a lens or a curved mirror, and the eyepiece, made up of a set of lenses.
With that being said and knowing that:
The focal length of the objective of a telescope (fo) = 75cm; The focal length of the eyepiece of a telescope (fe) = 6cm.
Changing the values:
So, The magnifying power of this telescope is 12,5.
