Power is the ratio between energy and time:
In our problem we have E=76 J and t=3.7 s. Therefore, the power is
Answer:
A magnet is demagnetized. There is a decrease in chemical potential energy. There is an increase in thermal energy. And there is an increase in energy in the form of demagnetization.
The first figure matches the description
The approximate diameter of an inflated basketball is <span>2 × 10^–2 m. The answer is number 1. The rest of the choices do not answer the question above because they are too big for the diameter of the basketball.</span>
Answer:
Given:
Time taken: 3.5 hrs
Speed: 120mi/HR
Now we know that
distance = speed x time
Substituting the given values in the above formula we get
Distance= 120mi/hr x 3 hrs
Distance = 360 mi= 579.36 Km
Explanation:
