Answer:
Force = 100N
Explanation:
Force = mass × acceleration
Answer:
Velocity is the speed of something given in a direction. the SI unit of velocity is metre per second or m/s.
<h3>
Answer: 10 kg</h3>
==================================================
Work Shown:
We have these variables
- p = momentum = 25 kg*m/s
- m = mass = unknown
- v = velocity = 2.5 meters per second
Solving for the mass gets us...
p = m*v
25 = m*2.5
25/2.5 = m
10 = m
m = 10
The mass of the horse is 10 kg.
Answer:
In contrast, the intrinsic brightness of an astronomical object, does not depend on the distance of the observer or any extinction. The absolute magnitude M, of a star or astronomical object is defined as the apparent magnitude it would have as seen from a distance of 10 parsecs (33 ly).
