The longer the time taken, the lower the power output.
This is since power is calculated through
Energy transferred / time
Increasing the denominator will lead to a lower value overall
<span>1Seek explanations for observed phenomena that rely solely on natural causes
2Progresses through creating and testing models of nature that explain observations as simply as possible
3Scientific model must make testable predictions; abandon or revise model if predictions do not agree with observations</span>
I think the answer is B 1:100
Given:
The mass of each sphere is
The distance between the two spheres is r = 2 m
To find the gravitational force that one sphere exerts on the other.
Explanation:
The gravitational force is caculated by the formula
Here, the universal gravitational constant is
Substituting the values, the gravitational force will be
Final Answer: The gravitational force that one sphere exerts on the other is 1.04 x10^-8 N.
Formula for stopping distance can be calculated by
here
now we can see from above equation that stopping distance depends on square of the speed.
So as we can see that here 30 mph and 60 mph, if the speed is double then the stopping distance will become four times more.
