Answer:
The current pass through the coil is 6.25 A
Explanation:
Given that,
Diameter = 25 cm
Magnetic field = 1.0 mT
Number of turns = 100
We need to calculate the current
Using the formula of magnetic field
Where, N = number of turns
r = radius
I = current
Put the value into the formula
Hence, The current passes through the coil is 6.25 A
An EM wave with a frequency of 10 7 Hz would be classified as infrared because of the frequency of 10 7 Hz
Answer:
s=800 m
Explanation:
Given that,
Acceleration of a runner, a = 4 m/s²
Time, t = 20 seconds
We need to find the distance covered by her. Initially, she was at rest. It means its initial velocity is equal to 0. So, using second equation of motion as follows :
Herre, u = 0
So, she will cover a distance of 800 m.
Yes i agree with that tbh beciase i think it does do so
