Answer:
20,000 Ns
Explanation:
mass of exhaust gases, m = 50 kg
velocity of exhaust gases, v = 400 m/s
The momentum of a body is defined as the measurement of motion of body. mathematically, it is defined as the product of mass off the body an its velocity.
change in momentum of rocket = final momentum - initial momentum
= m x v - 0
= 50 x 400
= 20,000 Ns
Answer:
The overall sky a Bellingham observer would see is about 75-100% over the period of 1 year.
Explanation:
Due to following factors, the overall sky visibility will fall in this range.
