Answer:
Electric current can best be induced in a wire by moving a magnet up and down near the wire is the correct answer.
Explanation:
Electric current is the flow of electron that carries the negative charge in the electric circuit.
Electric current induced in the wire through:
- Electric current is induced in the wire when the magnet moves in and down of the wire that is connected to a very high resistance voltmeter and when we move the magnet up and down the magnetic flux gets change and these changes produce induced current
- When the coil of wire is put in the magnetic field which is changing then the current will be induced in the wire.
Answer:
1.54 s
Explanation:
Considering that the legs constitute 16% of the total weight of the man then mass,
The legs also constitute 48% of his height hence
The moment of inertia of a cylinder rotating about a perpendicular axis at one end is hence
We also know that the period is given by
Here, h=0.5H= 0.5*0.8784=0.4392 m
Taking g as 9.81 kg/m2 then
Answer:
250 cm³
Explanation:
given,
Length of the Box, L = 5 cm
Width of Box, W = 5 cm
height of the box, H = 10 cm
Volume of the Box = L W H
V = 5 x 5 x 10
V = 250 cm³
Volume of the box is equal to 250 cm³
