Before the asteroid is threw, the total momentum is zero,
since neither Superman nor the asteroid are moving.
Conservation of momentum commands the total momentum after the astronaut is threw
must be zero too. This means that Superman's backward momentum afterward throwing
the asteroid is equivalent to the asteroid forwards momentum, in size.
Momentum is mass times velocity. We know the mass of the asteroid is 1000M and
its velocity is 850 m/s, so its momentum is
(1000M)(850 m/s) = 850,000M m/s.
So to get the answer: dividing by
Superman's mass, M, gives his recoil velocity o 850,000 m/s.
Answer:
the hypothalamus part of your brain sends a message to your body telling it to sweat.
When your internal temperature rises, your sweat glands release water to the surface of your skin.
I'm sorry, but this is not a question. What do you need to know?
Answer
A) Positively charged two insulating rod are brought closed to an object they repel each other. It means the Object is positively charged. Because similar charge repel each other.
The correct answer is Option A.
B) we know force between to charges is calculated using Formula
.......(1)
form the given condition in the question



from equation (1)

hence, the correct answer is Option C.
