George pushes a wheelbarrow for a distance of 12 meters at a constant speed for 35 seconds by applying a force of 20 newtons. what is the power applied to push this wheelbarrow? a. 1.2 watts b. 3.4 watts c. 17.15 watts d. 13 watts

To calculate the power applied to push the wheelbarrow, we use the formula

Here, F is applying force to pushes a wheelbarrow for a distance l in time t s.

Given, , and .

Substituting these values in above equation, we get

Thus, the power applied to push this wheelbarrow is 6.9 W.

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

what type of charge does it have? negative
