What changes a sound wave into an electric current?
Sound waves are longitudinal waves. These would vibrate a diaphragm which has been attached with a coil kept in a magnetic field. As the coil vibrates then current is induced. This is how sound wave gets changed into electric current.
Describe how a change in resistance would affect the current in a circuit?
As long as the voltage between the ends of the circuit remains constant, the current through the circuit is inversely proportional to the total effective resistance of the circuit.
Why would it be incorrect to refer to shear strength in g or kg?
it would be incorrect to refer to shear strength in g or kg because shear strength is a force not mass
How is lenz's law special case of the law of conservation of energy?
Lenz's law is a special case of the law of conservation of energy because it describes the relationship between the induced electromotive force (emf) and the change in magnetic flux in a closed loop. According to Lenz's law, the direction of the induced emf will be such that it opposes the change in magnetic flux, leading to the conservation of energy. This means that any change in the magnetic field will result in the generation of a current or emf that counteracts that change, thereby conserving energy.
If you pushed the ball to start it moving how would the strength of the push affect it's motion?
F = m * a Force (the push) equals mass (the "weight" of the ball) times acceleration (the rater of speed increase) The duration, direction, and the amount of force applied by the push affect the final velocity (the effect of the acceleration on the ball).
What happen in coil of wire when you pass a magnet through it?
A current would be induced in the coil.
Why LV side is shorted in short circuit test?
Transformer short circuit tests are used to determine the impedances (positive and zero sequence) of the transformer. A simple explanation: to do this one winding is shorted, and voltage is applied to another winding to circulate the normal full load current of the transformer. The impedance of the transformer is the applied voltage divided by the induced current. If one winding was not shorted, the voltage divided by induced current would not give the impedance of the transformer - the induced current would be much lower, giving a much higher impedance measurement that would be essentially meaningless.
Would you expect to find an alternating or direct current in the secondary coil of a transformer?
An Alternating Voltage is induced in the secondary winding. When connected to an external load, you will have an alternating current.
What will be the direction of flow of current in inductor circuit without any source?
With no source, there would be NO current flow. However, if a magnet were to be swiped past the inductor, a charge would be *induced* into the inductor, creating a small. The direction of current flow would depend on which way the magnet was swiped. If you reverse: magnet direction, magnet pole, or the winding direction, you will reverse the flow of current in the inductor. Yes, I mean induced, not inducted. To induct is to introduce, and to induce is to persuade.
How large a free weight set is big enough for a high school basketball player?
That would depend on the individuals current weight, strength and overall current body strength.
What would be the direction of the induced current if the s-pole of a bar magnet were quickly withdrawn from it?
That depends on the direction in which the coil of wire is wound.
What factors would affect the strength of the temporary magnet?
It depends on how you magnetize the temporary magnet.Material: Hard steel are harder to magnetize but harder to demagnetize compared to soft iron, so depending on duration, hard steel might be better (the longer the duration the better hard steel will be)Strength of original magnet (by induced magnetism): Of course, the stronger the first magnet, the more magnetism will be transferred.Number of coils (by electromagnetism): The more the merrier of course, where more coils mean more current flowing through (or around) it.

How would the spoils system affect a political party?
The political would have more strength int the government.
How would spoils system affect a political party?
The political would have more strength int the government.
What is the affect if the pressure and the distance by kicking a soccer ball?
if a person is strong nothing would have an affect. it depends on the pressure and strength used.
Are there any substances that can affect the strength of a magnet?
Grape jelly can. I know this souunds weird but as I was making a sanwhich I dropped jelly on my magnet. Me being curious I wanted to see if it would affect it's strength, and it did. Your Welcome
