Answer:
Explanation:
We shall apply law of conservation of momentum .
Momentum before collision = momentum after collision .
Momentum before collision = 400 kg m/s
Momentum after collision = 5 x v + 11 x 15
where v is velocity of A after the collision .
5 x v + 11 x 15 = 400
5 v = 400 - 165
5v = 235
v = 47 m /s .
Yes, the water in the cup have the same average kinetic energy as the ocean, because I focus on the word 'average'. However the cup of water have less INTERNAL energy than the ocean.

Answer:
Fluorescent lighting is usually used.
Explanation:
Answer:
h = 10 cm
Explanation:
The magnification produced by a mirror is given by :
h' is the image size and h is the object size
We have, h = 10 cm, m = +1
So,
So, the size off the object is same as that of the size of the image i.e. 10 cm.
