A magnet is plunged into and out of a coil of wire 2 times per second This induces 5 volts If the rate of motion changes so that the magnet is plunged in and out 6 times per second what will be the?

15 volts because :
2 times in a second=5volts
then
6 times in a second=15 volts

Why does motion occurs?
motion occurs when an object changes its position relative to a reference point.
' uniform motion in a circle in which speed is constant but velocity is changing'?
This is because the term "velocity" includes a specification both of a speed, and a direction. The direction changes, therefore the velocity changes.
Where is the speed of a simple harmonic oscillator equals to zero?
At the highest and lowest extremes of its travel, at the points where it changes its direction of motion.
What is rectilinear motion?
The motion along a straight line is known as rectilinear motion.
What is motion perpendicular to the ground?
Vertical motion is the motion that is perpendicular to the ground.
A magnet is plunged into and out of a coil of wire 2 times per second this induces 5 voltsif the rate of motion changes so the magnet is plunged in and out 6 times per second what would be the voltag?
2 times per second x (2.5)= 5 volts 6 times per second x (2.5)=15 volts
If the rate of motion changes so that the magnet is plunged in and out 6 times per second what will be the new induced voltage?

What uses a magnetic field to turn motion to electricity?
A microphone is a good example of a device that utilizes electromagnetic induction (Faraday's Law) to convert motion (vibrations in air) into electricity. The sound vibrates a membrane attached to a little magnet inside a coil of wire. The changing magnetic field induces a current in the wire.
When there is a change in the magnetic field in a closed loop of wire?
This can be done by moving a magnet through a coil of wire. This is called electromagnetic induction and it results in a voltage being induced in the coil. The charges in the coil are set in motion...

Why will a bar magnet fall slower and reach terminal velocity in a vertical copper or aluminum tube but not in a cardboard tube?
This is an aspect of Lenz's law. Copper is a non magnetic substance but is a conductor. When a magnet moves through the copper pipe it induces a current known as eddy currents. There will be a magnetic field created by the current. According to Lenz's law it will oppose the motion or change which is producing it. This results in an attractive force between the magnet and the copper pipe in which a current is induced by the falling magnet. The plastic rod is not conducting and hence it will not affect the fall.
Is it false that a strong magnet will cause a larger change in motion than a weak magnet?
no
The resistance of an object to changes in its motion?
The resistance of an object to changes in its motion is known as inertia. Changes in an objects motion include changes in its speed and direction.
When a strong magnet is passed rapidly through a coil of wire what is true?
The magnetic field lines (the lines of force) around the magnet sweep the windings in the coil. This induces a voltage in the windings (through induction), and the voltage will try to drive current if it can. There is a bit more to this, but the essential elements are that the magentic lines of force cause voltage in the coil because there is relative motion between the field and the coil.
How motion energy is converted into electrical energy in a generator?
Faraday showed hiow to do this in his Law: dB/dt = - DelxEv. A generator creates a changing magnet field and this induces an electric field in a circuit coupled to the changing magnetic.field. Hydroelectric plants use falling water to create the changing mag field.
What is key when using a magnet and a conductor to induce a current in the current?
Motion
