Given the fact that energy conversion is not entirely efficient, it is impossible to produce a perpetual motion machine.
<h3>What is a perpetual motion machine?</h3>
The perpetual motion machine in one that is able to work continuously without stopping. This would mean that the efficiency of this machine must that the machine is 100% efficient which violates the second law of thermodynamics.
Thus, given the fact that energy conversion is not entirely efficient and energy looses cause machines not function effectively, it is impossible to produce a perpetual motion machine.

Answer:
the answer to the question is the part that is reflected by clouds and atmosphere 26%
Answer:
P = (2 + 3) * V where V is their initial speed (total momentum)
P = 2 * 10 + 3 * Vx where Vx here would be V3
If the initial momentum is not known how can one determine the final velocity of the 3 kg obj.
Also work depends on the sum of the velocities
W (initial) = 1/2 (2 + 3) V^2 the initial kinetic energy
W (final) = 1/2 * 2 * V2^2 + 1/2 * 3 * V3^2

The value is 
Explanation:
Generally the moon's radial acceleration is mathematically represented as
Here 
is the angular velocity which is mathematically represented as
substituting 
for T(i.e the period of the moon ) we have
=> 
From the question r(which is the radius of the orbit ) is evaluated as
substitute 
for R and 
H
=> 
So
Answer
Force will be 1520.2604 N
Explanation:
We have given mass of the bullet m = 10.1 gram = 0.0101 kg
Distance S= 0.6 m
Final velocity v = 425 m/sec
Initial velocity u will be 0 m/sec
From third equation of motion 
We know that force is given by F = ma
So force = 0.0101×150520.833 = 1520.2604 N
