In a simple electric generator, a conducting loop of wire is placed in a magnetic field. The loop of wire is then rotated. Why i
kaheart [24]

Explanation:

If a coil of wire is placed in a magnetic field and rotated, an alternating (sinusoidal) current is induced. As it rotates, sometimes it is cutting through lots of magnetic flux, and so lots of current is

induced.

At other times, it is moving parallel to

the flux, and so no flux is cut, and no current is induced. In between, some current is induced. This creates an alternating current. Either end of the coil can be connected to wires outside of the generator in order to use the current elsewhere. This would be fine for the

first few rotations, but after this, the wires would get tangled up and the generator would be useless. To avoid this, we use a commutator. In an AC generator, this is a pair of rotating conducting 'slip rings' attached to either end of the coil. Carbon brushes bring these into contact with the outside world.

A car owner forgets to turn off the headlights of his car while it is parked in his garage. If the 12.0-V battery in his car is
luda_lava [24]

Answer:

It will take time=7.963 hours to completely discharge  

Explanation:

The energy available in the battery is:

Energy stored=Power×Time

Energy stored=(ΔV)I×t  

Energy stored=(12.0V×43.0A.h)

Energy stored=516 W.h

The two headlights together consume a total power of:

P=2*32.4W\\P=64.8W

So the time required to completely discharge is:

time=\frac{Energy.stored}{P}\\ time=\frac{516 W.h}{64.8W}\\ time=7.963hours

It will take time=7.963 hours to completely discharge

If the moon moved closer to the earth, how would the gravitational force between them change?.
hichkok12 [17]

If the moon moved closer to the earth, The gravitational force between them will increase.

This can be understood by Newton's law of universal gravitation. This is usually stated as that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

F_{gravitation} = G\frac{M_{1} M_{2}}{r^{2} }

If the moon moved closer to earth, the distance between them will be reduced, and as the force of gravitation is inversely proportional to the distance between the masses, the gravitation force increases.

Explain why gases are more compressible than solid
Oduvanchick [21]

Answer:

If we put pressure on a solid or a liquid, there is essentially no change in volume. ... The kinetic-molecular theory explains why gases are more compressible than either liquids or solids. Gases are compressible because most of the volume of a gas is composed of the large amounts of empty space between the gas particles.
