The correct order of events for the electromagnetic generators generate electricity is
b) The conducting coil rotates
c) The number of magnetic field lines passing through the coil changes
d) The flow of cuurent through the circuit
a)The stationary electrons in the wire experience a force.
The electromagnetic generators is working on the principle of electromagnetic induction. It has been used in many places as standby power sources in shops, homes etc.
It works by converting the mechanical energy into electrical energy by making use of electromagnetic conduction. which means the creation of current my moving the wire which is next to the magnet.

Answer:
a) 73.2N
b) 66.6N
c) 20.28N
Explanation:
F= mg=7.5×9.8=73.5N
Force parallel to the plane Fp= 73.5sin25= 31.06N
b) Fv= 73.5 cos25= 66.6N
c) Ff= u×Fv= 0.312×66.6=20.28N
a) Normal ForceFn= F/(cos25) - Fp - Ff = ma
1.1F -31.06-20.28=7.5×3.82
1.1F -51.84=28.65
1.1F= 28.65+51.84
F= 80.49/1.1
F= 73.2N
I think C and D are the best way to describe projectile motion since both left the ground and stayed aloft for a small or large amount of time. A and B are example of motion but not projectile
Primary sources are most often produced around the time of the events you are studying.

The reason as to why the substage condenser does not need to be included in computing the magnification and the only component needed is the ocular lens and the objective lenses is because the condenser is only responsible for gathering light and it does not contribute with the magnification of the object under the microscope.
