For this case we have that by definition, the momentum equation is given by:
Where:
m: It is the mass
v: It is the velocity
According to the data we have:
Substituting:
On the other hand, if we clear the variable "mass" we have:
According to the data we have:
Thus, the mass is 
Answer:
Answer:
Period is 1.57 seconds
Explanation:
From simple harmonic motion :
T = 2π√(2.5÷10)
T = 0.25 × 2π
T = 1.57 s
Atoms gain energy as a solid changes to a liquid. If atoms energy during a change of state, they are pulled together by attractive forces and become more organized.
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.
The longer the lever the longer the power
