A 9,100-microfarad [muF] capacitor is charged to 22 volts [V]. If the capacitor is completely discharged through an iron rod 0.2 meters [m] long and one-quarter centimeter [cm] in diameter, resulting in 80% of the stored energy being transferred to the rod as heat, how much does the temperature of the rod increase? Give your answer in kelvin [K].
Data you may need:
Specific Gravity of iron: SG = 7.874
Specific heat of iron: CP = 0.450 J/(g K)

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.

Would it be correct to say the doppler effect is the apparent change in the speed of a wave due to the motion of the source? be sure to fully explain your position using at least 3 complete content related sentences.
