Answer:
2.80 MJ
Explanation:
(a) We want to calculate the energy U of the battery, where its voltage is E = 13.0V and the supplied current is I = 60 A. We can neglect the internal resistance, so the terminal voltage equals the emf of the battery V = 13.0V. The quantity of delivered energy is given by the rate at which energy is delivered to it in a certain time t. We could obtain the rate at which energy is transferred by using equation , where the rate represents the power P = IV. Therefore, the energy produced is given by
U = P*t (P = IV)
U = I*V*t (1)
Now we can plug our values for I, V and t into equation (1) to get the energy produced in time t = 1 h = 3600 s
U = I*V*t = (60 A)(13 V)(3600s) = 2.80 MJ
The example of Newton's second law is that a runner accelerates at a rate of 1 meter per second per second during the race. The correct answer is C.
Using the second Law of Newton, F = m * a, you know that acceleration is maximum when the force is maximum.
Using Hooke's Law, F = K Δx, you know that the force is maximum when the displacement from the equilibrium (Δx) is maximum.
So the answer is that the acceleration is maximum at the maximum amplitude x = a.
I think so it ans wold be d.because if the source approaches the observer more and more wavefront will pass and it get squeezed.so wavelength decreases and frequency increases.
