Answer:
Part A
Newton's 3rd law states that action and reaction are equal and opposite, mathematically, we have;
= -
Where;
= The action force
= The reaction force
Part B
The law indicates that the force with which a rocket ship uses in taking off from the Earth,
is equal in magnitude, and opposite in direction to the reaction force of the Earth to the motion of the rocket, (-)
Part C
The law is a universal law, and it will also affect the rocket ship in space, as the force of the jet from the exhaust is directed towards Earth while in space, the rocket is propelled deeper into space
Explanation:
Answer:
B. posititvely charged particles
Explanation:
Opposites attract to each other, and the same charge repels.
Answer:
For example, when a car travels at a constant speed, the driving force from the engine is balanced by resistive forces such as air resistance and friction in the car's moving parts. The resultant force on the car is zero.

Answer:
The magnitude of the acceleration of the electron at this point is
.
Explanation:
Given that,
Velocity 
Angle = 61.5°
Magnetic field = 0.01 T
We need to calculate the magnetic force
Using formula of magnetic force

Where, B = magnetic field
v = velocity
e = charge of electron
Put the value into the formula


We need to calculate the acceleration
Using newton's second law


Put the value into the formula


Hence, The magnitude of the acceleration of the electron at this point is
.
