Answer:
So for an object moving in a circle, there must be an inward force acting upon it in order to cause its inward acceleration. This is sometimes referred to as the centripetal force requirement. The word centripetal (not to be confused with the F-word centrifugal) means center seeking.
Explanation:
hope this helps
The answer is 8 because multiplying 7 and 8 is 56
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>
Resistance = (voltage) / (current) =
(120 V) / (0.5 A) = <em>240 ohms</em>
D=m÷v
so density would be 57.9 ÷ 3 = 19.3 g/cm³
