Answer:
The average emf induced in the coil is 175 mV
Explanation:
Given;
number of turns of the coil, N = 1060 turns
diameter of the coil, d = 20.0 cm = 0.2 m
magnitude of the magnetic field, B = 5.25 x 10⁻⁵ T
duration of change in field, t = 10 ms = 10 x 10⁻³ s
The average emf induced in the coil is given by;
where;
A is the area of the coil
A = πr²
r is the radius of the coil = 0.2 /2 = 0.1 m
A = π(0.1)² = 0.03142 m²
Therefore, the average emf induced in the coil is 175 mV
Answer:
.004 Hz
Explanation:
Frequeny is cycles per second. An oscillation is 1 cycle
F=cycles/sec
4/100
=0.004Hz (Hz- Hertz=1 cycle/sec)
From the calculation, the acceleration of the body is 26m/s^2.
<h3>What is motion under gravity?</h3>
When an object is thrown up or down, the motion of the body is influenced by the gravitational pull on the body.
Now;
Given that;
v = 39 m/s
t = 1.5 s
u = 0 m/s
a = ?
v = u + at
v = at
a = v/t
a = 39 m/s/1.5 s
a = 26m/s^2
