Answer:
Explanation:
From the question we are told that:
Bowling ball Speed
Beach ball Speed
Let The Mass be equal i.e
Therefore
Generally the equation for Velocity of beach ball after collision is mathematically given by
Since Velocity is Vector Quantity
Therefore
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.
