The correct answer is D. Atoms of the same element can have different number of neutrons.
Answer:
Number of turns in secondary is 20
Current in primary is 0.96 A
Explanation:
We have given number of turns in primary
Voltage across primary of transformer
Current in secondary coil
Voltage across secondary
For transformer we know that
So
So number of turns in primary is 20
Now
Current in primary of transformer is 0.96 A
Option 3) a Soccer Ball
will travel the farthest distance.
Answer:
A brighter light
Explanation:
Light waves travel through space via light particles called photons. This particles have in essence 2 properties: 1. Amplitude and 2.Frequency. The first one has to do with the intensity of light we see and the second one has to do with the energy (color). If we change only the amplitude, we will see a lighter or darker light and will keep the same color in all amplitude changes. But if we modify the frequency, the intensity will keep the same and the color changes as we move into the light spectrum.
Thus, increasing the amplitude, we will perceive a brigher light.
Answer:
<h3>The maximum possible torque is τ =
N .</h3>
Explanation:
Given :
No. of turns
Radius of circular coil m
Magnetic field T
Current A
For maximum torque,
τ =
Where area of coil =
For maximum possible torque ,
τ =
τ = N
