<span>The fact that light travels at 300,000 km/s is a consequence of Energy Conservation
The particle that move with that kind of speed creates energy way faster than the particle that don't. Which means that it would require less effort to produce the energy,</span>
Answer:
The value is
Explanation:
From the question we are told that
The current is
The radius is
The length of the wire is \
The resistance is
The outer surface temperature is
The average thermal conductivity is
Generally the heat generated in the stainless steel wire is mathematically represented as
=>
=>
Generally the middle temperature is mathematically represented as
Answer:
Explanation:
For the first ball, the moment of inertia and the kinetic energy is:
So, replacing, we get that:
At the same way, the moment of inertia and kinetic energy for second ball is:
So:
Then, is equal to , so:
Finally, solving for , we get:
The tendency for two masses alone in the universe to drift together is a result of gravitational pull.
