Answer:
False
Explanation:
Diffraction is slight bending of the light as it passes around edge of object.
It is caused as one wave of the light being shifted by the diffracting object. The shift will then cause wave to have the interference with itself. The interference can be constructive or destructive.
The patterns of the interference rely on size of diffracting object and size of wave.
Hence, the given statement is incorrect.
Answer:Kinetic energy is the energy of motion. All moving objects have kinetic energy. When an object is in motion, it changes its position by moving in a direction: up, down, forward, or backward. 3. A force is a push or pull that causes an object to move, change direction, change speed, or stop.
Explanation: Not sure if that's what you meant but that's the answer I can give you.
Answer:
7.894 Hours.
Explanation:
Based on information number hours that this battery will last with give load has mathematical relation of.
with load 60A t = 1h, 30A t = 2h so on and forth.
two head lights draw total current of 2x3.8A = 7.6A.
putting this in above relation gives.
.
That is how long will it be before battery is dead.
