V = l x w x h
v = 3 x 6 x 4
v = 72
The distance starting from the point to the lighthouse would be regarded as the hypotenuse.
And also will be the radius of the circle the beam of light is generating at that point.
So get the radius first
r = sqrt (1^2 + 5^2)
r = 5.099 km
find the circumference:
C = 2*pi * 5.099 km
C = 2 * 16.01898094
C = 32.04 km
Then find the speed in km/sec
One revolution: 60/2 = 30 sec per revolution
Speed = 32.04 km/30 sec
S = 1.068 km/sec is the speed of light
Answer:
B. Nuclear to Electrical
Explanation:
Atoms are split at power plants to create electricity. The energy conversion in this process is from nuclear to electrical energy.
- When atoms are split, nuclear energy is released.
- Some part of the mass of the atom is converted to energy.
- The nuclear energy released is expressed as heat energy.
- This energy is used to heat water in boilers when produces steam that are used to drive the movement of turbines.
- This in turn generates electricity.
It depends who is watching it.
-- A passenger on the train says that his clock is normal, but the clock at the station he just passed is running slow.
-- A ticket agent at the station says that his clock is normal, but the clock on the train that just rolled through is running slow.
-- They're both correct, but ...
-- The difference is too small for either of them to notice, unless the train is going faster than about half the speed of light.
-- It isn't.
I am absolutely sure that if something is hot, it contain thermal energy only because <span>if a given body is heated its electrons start to move very fast which means that thermal energy is being produced. Hope everything is clear! Regards!</span>
