B is electrons and A is neutrons
Answer:
7142.86W
Explanation:
Given parameters:
Work done by brake = 40000J
Time taken = 5.6s
Unknown:
Power used by car = ?
Solution:
Power can be defined as the rate at which work is done. It is mathematically expressed as;
Power =
Now input the variables;
Power = = 7142.86W
The slope of the distance/time graph is the speed of the moving object.
So the graph for a fast moving object will have a greater slope than the
graph for a slower moving object has.
Answer:
A pair of light or sound waves will experience interference when they pass through each other. Destructive interference occurs when the maximal of 2 waves are 180 degrees out of phrase: A positive displacement of one wave is canceled exactly by a negative displacement of the other wave.
