Answer:
Explanation:
The equation for momentum is p = mv; therefore,
p1 = 50(4) so
p1 = 200
p2 = 50(5) so
p2 = 250
The impulse, the change in the momentum, is 50, going in the same direction.
The building sector plays a large role in the energy consumption which includes space heating or cooling, domestic hot water and electricity. Buildings with their long lifespan and huge amount of already existing buildings, makes revision in energy characteristics of a building constrained.
No, it couldn't be.
