Answer:
The soup still is cool, or since its recent it will take a while to get warmer
Explanation:
Answer:
Part a)

Part b)
this is a large potential which can not be possible because at this high potential the air will break down and the charge on the sphere will decrease.
Part C)
here we can assume the sphere is placed at vacuum so that there is no break down of air.
Explanation:
Part a)
As we know that the potential near the surface of metal sphere is given by the equation

here we have
Q = 8 C
R = 10.0 cm
now we have


Part b)
this is a large potential which can not be possible because at this high potential the air will break down and the charge on the sphere will decrease.
Part C)
here we can assume the sphere is placed at vacuum so that there is no break down of air.
The light bulb doesn't do any "work" ... it doesn't exert force,
or maintain a force through a distance. It does, however,
dissipate energy, in the form of heat and light.
The quantity of energy that it dissipates is ...
(4 watts) x (8 hours) x (3600 sec/hour) x (1 joule/watt-sec)
= (4 x 8 x 3600) joules = 115,200 joules .
<span>A wind tunnel is a traditional tool used for trans-sonic flight research. But, during those days, it’s not exact and consistent to use for aircraft flow conditions. The reason is that wind tunnel models will be visible to airflow that produces shock waves. So the U.S and Britain develop an instrument to get data and record flow conditions for a specified speed, these are the specialized research airplanes.</span>
The ratio of the turns to the voltage should be equal
i.e: 200/120 = t/12
so the secondary coil should have 20 turns
