Answer:
See the explanion below
Explanation:
Linear momentum is defined as the product of mass by velocity and can be calculated by the following equation.
where:
P = momentum [kg*m/s]
m = mass [kg]
v = velocity [m/s]
When the ball hits the wall it receives a force for a very short time, this time and force value is known as momentum and can be calculated by the following expression.
where:
m₁ = mass of the ball [kg]
v₁ = 5 [m/s]
v₂ = 5 [m/s]
v₁ = v₂
It can be said that the impulse is equal to 2 times the speed of throwing by the mass.
Answer:
The speed of the satellite is 7809.52 m/s
Explanation:
It is given that,
Radius of Earth,
Mass of earth,
A satellite moves in a circular orbit a distance of, above Earth's surface.
We need to find the speed of the satellite. It is given by :
R = r + d
So,
v = 7809.52 m/s
So, the speed of the satellite is 7809.52 m/s. Hence, this is the required solution.
Answer:
Explanation:
plate separation = 2.3 x 10⁻³ m
capacity C₁ = ε A / d
= ε A / 2.3 x 10⁻³
C₂ = ε A / 1.15 x 10⁻³
=
a ) when charge remains constant
energy =
q is charge and C is capacity
energy stored initially E₁=
energy stored finally E₂ =
=
=
=
= 4.19 J
b )
In this case potential diff remains constant
energy of capacitor = 1/2 C V²
energy is proportional to capacity as V is constant .
= 16.76 .
