Answer:
Net charge produce due to presence of different chargers in the vicinity or in the considered region.
Explanation:
Net electric charge is just a concept introduce to identify the result of the presence of number of charges which interact with each other. It can be found by treating electric chargers in algebraic form like numbers, where +charges get added with +charges
-charges get added with -charges
and when adding two charges with opposite signs they get subtracted and the symbol of the resultant charge comes from the charge with highest magnitude.
Answer:
A) must equal angle of reflection
Explanation:
"The angle of incidence is equal to the angle of reflection". This is true according to the first law of reflection. For this to be totally true, the plane surface in consideration must be a smooth surface. Since it is a law, it cannot be changed because it has been proved to be true.
Note that the angle of incidence is the angle between the incidence ray and the normal ray(this ray is perpendicular to the surface) while the angle of reflection is the angle between the reflected ray and the normal.
Answer:
MOTOR
Explanation:
The device which changes electrical energy into mechanical energy is known as motor
Answer: ma is the formula of Newton's Second Law of Motion. Newton's Second Law of Motion is defined as Force is equal to the rate of change of momentum. For a constant mass, force equals mass times acceleration.
Explanation: Newton's second law of motion is F = ma, or force is equal to mass times acceleration.
