Answer:
Explanation:
Given
mas of block
speed of block
spring constant
As the mass collides with the spring its kinetic energy is converted to the Elastic Potential energy of the spring
Answer:
The current flowing through the 4Ω resistor is;
C. 2.0 A
Explanation:
In the given figure, we have;
The series resistors in the bridge = 8Ω, and 4Ω are in series and 20Ω and 10Ω are in series
The sum of each of the series resistors are;
R₁ = 8Ω + 4Ω = 12Ω
R₂ = 20Ω + 10Ω = 30Ω
The equivalent resistors of the series resistors, R₁ and R₂ are parallel to each other
The current flowing through the 4Ω resistor = The current in R₁ = I₁
By the current divider rule, we have;
Therefore, I₁ = 2.0 A
The current flowing through the 4Ω resistor = I₁ = 2 A
Elephant D does because it is at the highest height and can exert a greater amount of force leading to a greater amount of energy
