Answer:
V=14
Explanation:
PE=KE
mgh=1/2mv^2
2(9.8)10=1/2(2)v^2
(radical) 196= (radical)v
V=14
Fish swimming forward in the water, the water gets pushed backward because the fish moving forward is forcing the water to move backward, the motion forward and backward are the same, they are opposite and equal.
The cart that has the smallest mass of sports equipment in it
has the greatest change in speed. We know this from Newton's
second law of motion ...
Force = (mass) x (acceleration).
If several objects have the same force acting on them, then the one
with the smallest mass has the greatest acceleration.
Answer:
A) is repelled by the sphere.
Explanation:
When a charged insulated rod is touched with an insulated conducting sphere , some charge on the rod gets transferred to the sphere . So they become similarly charged . We all know that there is repulsion when two similarly charged object are brought near to each other . Hence here too there will be repulsion between the rod and the sphere when the rod is brought near the sphere.
V1: How do you want the answer expressed?
V2:(I. other words..) In what terms do you want the answer expressed?
