Answer:
c. dioptre that's the answer.
It results change only in it's kinetic energy, it's KE will increase in accord with the work-energy theorem
Answer:
25lb
Explanation:
You haven't changed (you are made up of the same atoms), but the force exerted on you is different. Physicists like to say that your mass hasn't changed, only your weight.
Answer:
14523.55J
Explanation:
The work done by the jogger against gravity is given by the following equation;

where m is the mass, g is acceleration due to gravity taken as
and h is the height of the hill.
Since the length of the hill is 132m and it is inclined at 12 degrees to the horizontal, the height is thus given as follows;

Substituting this into equation (1) with all other necessary parameters, we obtain the following;

[r] =6
Solve for r by simplifying both sides of the equation, then isolating the variable.
<em> </em>I hope this makes sense
