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

here we know that
q = 0.000600 C

B = 4.21 T
now from above equation we have


direction of force is given by right hand thumb rule
using that rule we got force downwards
Answer:
The minimum stopping distance when the car is moving at
29.0 m/sec = 285.94 m
Explanation:
We know by equation of motion that,

Where, v= final velocity m/sec
u=initial velocity m/sec
a=Acceleration m/
s= Distance traveled before stop m
Case 1
u= 13 m/sec, v=0, s= 57.46 m, a=?

a = -1.47 m/
(a is negative since final velocity is less then initial velocity)
Case 2
u=29 m/sec, v=0, s= ?, a=-1.47 m/
(since same friction force is applied)

s = 285.94 m
Hence the minimum stopping distance when the car is moving at
29.0 m/sec = 285.94 m

An example of a negative incentive for producers is the
sharp increase in production costs. Producers are the one who manage the production
costs and even the production budget. Anything that relates the production
department is entitled to the management of production producers.
There is what we called positive and negative incentives and
both of these can affect consumers and producers. Positive incentives are those
situations which will give a certain outcome that will benefit the producers,
for example, during the peak season there will be a high demand of products, and
this gives the chance of producers to demand a higher price from the consumers,
in this situation, there will be a big chance of increase sales. A sharp increase in production costs is a
loss for the producers. If there will be
an increase in production costs, the budget will be greatly affective and even
though it is not a peak season, there’s a big chance also to increase prices
which we know, consumers are not fond of.
