Answer:
position, speed, direction, and acceleration.
Explanation:
Answer:
Explanation:
The energy a single photon of an electromagnetic wave is given by
where
h is the Planck constant
c is the speed of light
is the wavelength of the photon
In this problem, we have
is the energy of the photon
So we can re-arrange the equation to find the wavelength:
Answer:
the emf generated by a magnetic coil of the generator, because it consists of a coil turning in a magnetic field; it opposes the voltage powering the motor, so at first the current reaches 10A but subsequently due to the back emf generated in the coil this emf opposes the self induced emf thereby reducing the current to 4A
Explanation:
An electromagnet is a type of magnet in which the magnetic field is produced using the current. The simplest form of an electromagnet is a wire wrapped around in a coil.
The strength of magnetic field of such magnet is given with this equation:
Where N is the number of loops in the coil, I is the strength of the current flowing through the coil, L is the length of the coil, and
is <span>permeability of the electromagnet core material.
From this equation, we can see that increasing both the current and number of loops will increase the strength of the magnet.
Both BLANKS should be
Increase. When you use the additional battery you will have more voltage and more voltage means more electricity.</span>
