To be able to answer this item, we are to calculate the power that the machine could deliver from hp to kW.
(45 hp)(746 W/1 hp) = 33570 W
Power is the amount of energy delivered at a certain period.
t = (6.20 x 10^2 J)/ (33570 kJ/s)
t = 0.01845 s
Answer:
Sun heating a car sitting in a parking lot
Explanation:
The sun heating a car sitting in a parking lot is an example of electromagnetic waves transferring energy.
- Electromagnetic waves are produced from the vibration between electric and magnetic fields.
- These waves can be propagated through vacuum with no particles inside of them.
- The sun produces electromagnetic radiation through the process of nuclear fusion.
- These radiations are used to warm the earth surface.
- The sun heating a car sitting a parking lot is one vivid example.
The solubility of gases in liquids increases with the increase in pressure.
Answer:
North pole
Explanation:
According to the law of magnetism:
<em>Unlike poles attract while like poles repel</em>
Since the south pole of the steel is brought near the nail, and the nail is meant to attract the steel magnet, the nail domain realigns itself to produce a pole opposite to the pole of the steel magnet brought near it.
Since the North pole is the opposite of the south pole, the North pole will be at the pointed end of the nail so that it can attract the steel magnet.
