When the power in their house unexpectedly went off, Radhika's mother said that she would check and replace the fuse. What exact
denis23 [38]

A) a piece of wire

Explanation:

Radhika's mother is simply replacing piece of wire.

A fuse is made up of a thin strip of wire that melts when there is an over current.

  • A fuse is electrical safety device in circuit that protects appliances from over current.
  • The wire in a fuse has a high resistance and low melting point.
  • When current is high, the resistance of the wire causes it to melt and break the circuit.
  • In this way, appliances are protected from the harmful effect of the surge in voltage.

a student moves a box across the floor by exerting 23.3 N of force and doing 47.2 J of work on the box. How far does the student
kozerog [31]
Work = Force x Distance
47.2J = 23.3N x d
d = 47.2/23.3
d = 2.0258 m

hope this helps :P

A. How does increasing the voltage of a power supply in an electromagnet affect the strength of the magnetic field?
seropon [69]

PART A)

If we increase the voltage supply in an electromagnet then it will increase the current that is flowing in it

So here due to increase in current there will be increase in the magnetic field due to that electromagnet

PART B)

Here in electric generator the current is produced by rotating a coil between two strong magnets.

So here mechanical energy of rotation of coil is converted into electromagnetic energy.

PART C)

Step up transformer convert the lower voltage input into higher voltage output

here number of turns of coil in output side or secondary number of coils is more than the number of coils in primary side or input side

PART D)

Force on a moving charge is given by

F = q(\vec v \times \vec B)

here we know that

q = 0.000600 C

v = 2.8 \times 10^5 m/s

B = 4.21 T

now from above equation we have

F = 0.0006(2.8\times 10^5)(4.21)

F = 707.3 N

direction of force is given by right hand thumb rule

using that rule we got force downwards
