Answer:
momentum formula = Mass × Velocity
Based on the situation above the the work done was 400 Joules. <span>Q = FS cos(theta) is the so-called work function. It's important to learn the work physics; you'll see it over and over in science/physics class. Theta is the angle between the force vector F and the distance vector S. In your problem we assume theta = 0, the two vectors were assumed aligned.</span>
Answer:
the last one: weight force
Explanation:
The triple beam balance is used to measure masses very precisely; the reading error is 0.05g
