Answer:
this has to do with the drop in voltage, or potential as electrons traverse the material .
Answer:
Part a)
Part b)
Part C)
This is loss in terms of thermal energy due to collision with the floor
Explanation:
Part a)
Since we know that the ball rises up by 65% of initial height
so after first bounce it will lose 35% of its initial energy
so we will have
Energy Loss = 0.35 mgH[/tex]
Part b)
Energy of the ball after first bounce
energy of ball after 2nd Bounce
energy of the ball after 3rd bounce
Now we will have energy loss in fourth bounce given as
Part C)
This is loss in terms of thermal energy due to collision with the floor
Answer:
1) black body radiation
2) Electromagnetic radiation through the window
Explanation:
Blackbody radiation is the radiation produced by heated objects, particularly from a blackbody. The car is heated by sunshine. Actually, everything is heated by sunshine, and the car being a blackbody object absorbs all radiation (visible light, infrared light, ultraviolet light, etc.) that falls on it. This also means that it will also radiate at all frequencies that heat energy produces in it.
Radiation from the Sun is absorbed, through the glass, by the inside of the car. That is why it helps to have tinted glass or use a screen on the windows while it is parked.
Well, we know that mass is conserved, so the missing 4 kg couldn't
just disappear. It had to go somewhere.
It may have left the burning log in the form of hot gases and smoke particles.
