While trying out for the position of pitcher on your high school baseball team, you throw a fastball at 87.6 mi/h toward home pl
ate, which is 18.4 m away. how far does the ball drop due to effects of gravity by the time it reaches home plate? (ignore any effects due to air resistance and assume you throw the ball horizontally.)?

Answer:
The resistance that will provide this potential drop is 388.89 ohms.
Explanation:
Given;
Voltage source, E = 12 V
Voltage rating of the lamp, V = 5 V
Current through the lamp, I = 18 mA
Extra voltage or potential drop, IR = E- V
IR = 12 V - 5 V = 7 V
The resistance that will provide this potential drop (7 V) is calculated as follows:
IR = V
Therefore, the resistance that will provide this potential drop is 388.89 ohms.
