Explanation:
that's impossible,the radius of the earth can't decrease when the mass doubles!
Answer:
C) W = - 190 J
Explanation:
Notation
Wf = work done by the friction force (unknown)
Ff = force of the friction
d = distance travelled by the box = (2 pi 1.82 m) = 11.435 m
The vector sum of forces acting on a non-accelerating object equals zero.
equation form: ΣF = 0
I think it's D because sunlight is a solar system
