Answer:
Number of turns,
Explanation:
Given that,
The maximum strength of the Earth's magnetic field,
This field could be used with a rotating coil to generate 60.0-Hz ac electricity.
Let us assume that the coil must have to produce an rms voltage of 120 V and area per turn is 0.022 meter square.
The emf induced in the coil is given by :
N is the number of turns
f is the frequency
or
So, there are turns in the coil.
Answer:
(A) Torque required is 21.205 N-m
(b) Wok done will be equal to 1199.1286 j
Explanation:
We have given moment of inertia
Wheel deaccelerate from 135 rpm to 0 rpm
135 rpm =
Time t = 8 sec
So angular speed and
Angular acceleration is given by
Torque is given by torque
Work done to accelerate the vehicle is
Answer :Scientific Definition of Inference
In science, there are a few different types of inferences, but in general an inference is: “An educated guess made through observation.” You might use these inferences to share a potential reason why something happens or how it happens.
