Answer:

Gases and particles in Earth's atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.

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
