Answer:
The angular frequency is the coil rotating is 1.9 rad/s.
Explanation:
Given that,
Number of turns = 600
Radius = 15 cm
Magnetic field = 0.020 T
Maximum induced emf = 1.6 V
We need to calculate the angular frequency is the coil rotating
Using formula emf
When induced emf is maximum so will be 1.
Where, N = number of turns
A = area
B = magnetic field
Put the value into the formula
Hence, The angular frequency is the coil rotating is 1.9 rad/s.
<h2>Given :-</h2>
- Weight = 20 N
- Acceleration = 2 m/s
- Force applied=?
As we know that,
<h3>F = ma</h3>- F is the Force applied
- M is the Mass
- A is the Acceleration
<u>According</u><u> </u><u>to</u><u> </u><u>the question</u><u>, </u>
F = 20 × 2
F = 40 N
<h3>Hence :-</h3>Force applied is 40 N
