As mass increases what happens to the kinetic energy

1 answer:

5 0

As mass increases kinetic energy also increases; kinetic energy is directly proportional to mass so whatever is done to either affects the other one the same. i hope this helps :)

GuDViN [60]

Answer:

20 hertz of frequency produced.

Explanation:

$\boxed{frequency = \frac{1}{period} }$

Here we will find frequency and period should be in second, here given: 0.05 seconds

using the formula:

$\boxed{frequency = \frac{1}{0.05} }$

$\boxed{frequency =20}$

puteri [66]

Correct question:

A solenoid of length 0.35 m and diameter 0.040 m carries a current of 5.0 A through its windings. If the magnetic field in the center of the solenoid is 2.8 x 10⁻² T, what is the number of turns per meter for this solenoid?

Answer:

the number of turns per meter for the solenoid is 4.5 x 10³ turns/m.

Explanation:

Given;

length of solenoid, L= 0.35 m

diameter of the solenoid, d = 0.04 m

current through the solenoid, I = 5.0 A

magnetic field in the center of the solenoid, 2.8 x 10⁻² T

The number of turns per meter for the solenoid is calculated as follows;

$B =\mu_o I(\frac{N}{L} )\\\\B = \mu_o I(n)\\\\n = \frac{B}{\mu_o I} \\\\n = \frac{2.8 \times 10^{-2}}{4 \pi \times 10^{-7} \times 5.0} \\\\n = 4.5 \times 10^3 \ turns/m$

Therefore, the number of turns per meter for the solenoid is 4.5 x 10³ turns/m.

Which part of the electronic system of a tape player would be different from that of a record player?

Luda [366]

Answer:

In a tape player sound is stored in the tape then from the tape,sound is converted to electrical signals then to the ears where as in a record player electric signals from the spinning cord are feed directly into an amplifier connected to a loudspeaker for us to hear.

Explanation:

In a record player, magnetic devices convert sound vibrations originating from from a spinning record into electric signals that are feed into an amplifier in a loudspeaker to make us hear the sound.A tape player utilizes a magnetic tape as the medium where the sound is stored into the tape.Here sound waves are converted into electric signals in the recorded and the sound wave goes to our ears due to polarity changes caused by the small magnets in the headphones.
