In a series circuit, a common current flows through all the components of the circuit. While in a parallel circuit, a different amount of current flows through each parallel branch of the circuit. Whereas in the parallel circuit, the same voltage exists across the multiple components in the circuit.

Answer:
D) All of these
Explanation:
The magnetic flux through a coil of wire is given by:
where
B is the intensity of the magnetic field
A is the area enclosed by the coil
is the angle between the direction of B and the normal to the area of the coil
Therefore, we see that the magnetic flux depends on all these quantities:
A) the magnetic field
B)the orientation of the field with respect to the region through which it passes
C)the area of a region through which magnetic field passes
So, the correct answer is
D) All of these
The efficiency of the machine is defined as
Here
Work out is the work output and Work in is the work input
To find the Work in we have then
Replacing with our values
The work done by the applied force is
W = Fd
Here,
F = Force
d = Distnace
Rearranging to find F,
F = 129.77N
Therefore the force exerted on the machine after rounding off to two significant figures is 130N
