According to the law of reflection, when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.
So in the above situation, if the incident ray makes an angle of 65° with respect to the normal to the mirror's surface, the angle of reflected ray will also be equal to 65 degrees. The attached image will explain this better.
So the answer is,
c. 65 degrees
Impulse equals to the force into the actual time period of the applied force . thus the force here given is 245.300 N and time is 0.05 thus the impulse is 12.265 Ns
Answer:
Explanation:
A mover carries a box across a room. A weightlifter lifts a barbell off the ground. A weightlifter holds a barbell above the head.
that what i think
The answer is A. Increase
The formula is <span>Voltage = Resistance X Current
Lets say the voltage is 10 and the resistence is 5
10 = 5 x current
Current = 2
Now, lets decrease the resistence from 5 to 2
10 = 2 x Current
Current = 5
The current increases

Answer:
b. The rate at which charge flows
Explanation:
First we must complete the question:
Which of the following describes the measure of current:
a. The quality of the charge flow
b.The rate at which charge flows
c. The ability for something to have a charge flow
d.The potential for a charge to flow
The answer is b) The rate at which charge flows
The electric current is the electric charge flow that passes through a conductive material for a certain period of time. It is expressed in C / s, culombios per second in the international system of units, and the unit is known as Ampere (a)
The charge can be defined by culombio [C]
