Explanation:
Momentum before = momentum after
(5 kg) (0 m/s) = (2 kg) (60 m/s) + (3 kg) v
v = -40 m/s
Total kinetic energy is:
KE = ½ (2 kg) (60 m/s)² + ½ (3 kg) (-40 m/s)²
KE = 6000 J
Answer:
0 J
Explanation:
Work = force × distance
Since the object isn't moved, the distance is 0. So the work is 0.
according to the question are microwaves and X-rays
<span>The answer is transformer. They utilize
electromagnetic induction to generate current. This is only possible in
alternating current due to the differential increase and decrease of electrical
current that induces changes in magnetic flux in the coil. This varies the
magnetic flux of the primary coil that generates current in the secondary coil.</span>
