How this induced force can be increased? Write three ways.

1 answer:

8 0

Strength of induced current increased when strength of magnetic field increases. It will also increase when the number of turns are increased or if the speed of conductor increases

Name:

Brums [2.3K]

Answer:

1.a) 1 kJ

1.b) 4 kJ

ratio 1:4

1.c) 4 times as before

2.a) 3.33 m/s2

Explanation:

1.a) bicycle's velocity =Displacement/time

=100/20 m/s

=5 m/s

bicycler's KE =1/2 *mass*(velocity)^2

=1/2*80*5^2

=1000 J = 1 kJ

1.b) bicycle's new velocity =200/20 m/s

=10 m/s

bicycler's new KE =1/2*80*10^2

=4000 J = 4 kJ

Ratio= KE 1 :KE new

= 1 :4

1.c) when bicycler's speed was doubled it increased the KE by 4 times (2^2). because In KE we consider the square of the speed , so the factor we increase the speed , the KE will get increased with the square value of it

ex : speed is triple the prior value , then the KE is as 3^2 times as before. that is 9 times

2.a) car acceleration = (20-0)/6 m/s2

= 3.33 m/s2

Will the velocity of the book change as it moves across the surface with NO friction? Explain your answer.

MakcuM [25]

No velocity will not be changed

Why?

According to Newtons 1st law the velocity of a moving object remains unchanged unless a external force affect that.

A spherical conductor is inside a uniform electric field with a magnitude of 1000 N/C to the right. What is the magnitude and di

Lyrx [107]

Answer:

1.-E=1000N/C to the LEFT

2.-The electric field inside a conductor in electrostatic state is always zero (conductor proprieties).

3.-The voltmeter read 0V as differential voltage between two points from the conductor

Explanation:

1.The electric field inside the conductor must be zero (conductor proprieties). Then the charges create a electric field equal an opposite to the external electric field. In other words E=1000N/C to the LEFT

2. The electric field inside a conductor in electrostatic state is always zero. As shown in the figure the electric field induced by the charges in the sphere surface cancelled the EXTERN electric field.

3.If the Electric field inside the conductor is zero, that means that the Voltage in the hole conductor is constant (conductor proprieties). In other words the the voltmeter read 0v as differential voltage between two points from the conductor.
