Answer:
Efficiency = 71%
Explanation:
Given the following data:
Output energy = 250 Joules
Input energy = 350 Joules
To find efficiency;
Substituting into the equation, we have;
Efficiency = 71.43 ≈ 71%
Therefore, the efficiency of the candle is 71 percent.
since centripetal acceleration is always towards the center of the circle
so at the given position where speed and acceleration is given the center coordinate will be towards the center of circle
also we know that
so the coordinates of the center will be
so the coordinate is (3.20 m, 4.04 m)
