Answer: the difference in the number of turns in each coil
Explanation:
A transformer is a device which is used transfer electrical energy from one circuit to another. It uses coils - primary and secondary having different turns. The current passes through the primary coil which induces emf in the secondary coil. The increase in potential depends on the number of turns in the coil.
where V is the voltage and N is the number of turns.
Answer:
The corresponding dimensions will be "x = 300 & y = 60".

Dimensions of the rectangular area:
x = 300
y = 60
1) The weight of the object is 1333 N
2) The mass of the object is 136 kg
Explanation:
1)
The work done when lifting an object is equal to the change in gravitational potential energy of the object:
where
F is the weight of the object
d is the distance through which the object has been moved
In this problem, we know that
W = 3200 J is the work done
d = 2.40 m is the distance through which the object has been lifted
Solving for F, we find the weight of the object:
2)
The weight of an object is given by
where
F is the weight
m is the mass of the object
g is the acceleration of gravity
In this problem, we know that
F = 1333 N is the weight of the container
is the acceleration of gravity
Solving for m, we find the mass of the container:
