Answer:
p = mv
Explanation:
- The momentum of a body is defined as the product of its mass and velocity. Its physical symbol is 'p'.
- The formula for momentum is given by
p = mv
Where,
m - the mass of the body in kg
v - velocity of the body in m/s
- Therefore, the unit of momentum is expressed as the kg m/s
- The momentum of a body is always associated with its motion. It is a vector quantity and it is directed in the direction of the velocity vector.
- If a body is at rest, the momentum associated with the body is zero.
- The momentum plays a significant role in the kinematics of the body. As similar to the energy conservation law, the total momentum of the body is conserved.
Mass is measured in kg.
1N = 0.10197kg
0.10197 x 16
= 1.63kg.
Answer:
Explanation:
Some data in the problem are missing.
Missing values:
Radius of the cylinder: 13 cm
Height of the cylinder: 4 cm
The volume of a cylinder is given by
where
r is the radius of the base of the cylinder
h is the height of the cylinder
In this problem, we have:
r = 13 cm (radius)
h = 4 cm (height)
Therefore, the volume of the cylinder is:
Depends on what the area is. If it’s a rural place, Wood is cheep & easy to build. If there’s a lot of corrosion, strong weather/hurricane, bricks.
