The radius of Earth's circular trajectory is
The time for the Earth to travel around the Sun is
Thus the velocity is velocity
From this we can deduce the centripetal acceleration
Angular velocity is
Answer:
2991.42 N
Explanation:
For this problem, we'll use the equations: momentum= mass x velocity and impulse = change in momentum, and impulse=force x time.
initial momentum; p1 = 0.17 x 41 = 6.97 kg.m/s
final momentum; p2 = 0, because final velocity is 0 m/s
Thus,
impulse = p1 - p2= 6.97 - 0 = 6.97 kg.m/s
Finally, impulse= Force x time,
Thus, Force = Impulse/time
Force= 6.97/ (2.33 x 10^(-3)) = 2991.42 N
Virtual images are produced when rays of a light (after reflection or refraction) appear to meet a a certain point. While real images are produced when rays of a light (after reflection or refraction) meet at some point.
Hello,
Here is your answer:
The proper answer to this question is option D "<span>centrifugal".</span>
The force centrifugal is the force that holds the moon with the Earth and the centrifugal force is two times stronger with the Earth and the sun.
Your answer is D.

Answer:
A= 203 KJ
B= 54 Kg
Explanation:
The initial specific volumes and internal energies are obtained from A-12 for a given pressure and state. The enthalpy of the refrigerant in the supply line is determined using the saturated liquid approximation for the given temperature with data from A-11. The mass that has entered the tank is:
Δm = m₂ – m₁
= V(1/α₂ – 1/α₁)
= 0.05 (1/0.0008935 – 1/ 0.025645)Kg
= 54Kg
The heat transfer is obtained from the energy balance:
ΔU= 
+ 
m₂u₂ – m₁u₂ = +
= m₂u₂ – m₁u₁ –
= V/α₂u₂ - V/α₁u₁ –
=(0.05/0.0008935 . 116.72 – 0.05/0.025645 . 246.82 – 54.108.28) Kj
= 203 KJ
