The equivalent resistance of the two cylindrical conductors connected in parallel is 466 ohm.
<h3>Resistance</h3>Resistance is a measure of the opposition to flow of electric current. It is measured in ohms.
It is given by the formula:
Given that R₂ = 469 ohm, hence:
But l₁ = 6l₂, r₁ = (1/5)r₂, hence:
The equivalent resistance (R) is:
The equivalent resistance of the two cylindrical conductors connected in parallel is 466 ohm.

Answer:
Acceleration of the box is 4.9 m/s².
Explanation:
The free body diagram is shown below.
The weight of the body can be resolved into two mutually perpendicular components as shown. The force responsible for sliding motion of the box along the incline is due to acting along the incline.
Therefore, as per Newton's second law of motion,
Net force =
Now, net force acting along the incline is only
Therefore,
Now,
Therefore, the acceleration of the box is given as:
Acceleration of the box is 4.9 m/s².
Answer:
The the average magnitude of the force exerted on the ball by the floor N
Explanation:
Given:
Mass of ball kg
Initial speed
Rebound speed
Contact time interval sec
For finding the average magnitude of the force on the ball by the floor is given by,
Here
N
Therefore, the the average magnitude of the force exerted on the ball by the floor N
