A very long half-cylinder of radius r carries a total current is uniformly distributed across the circumference. Determine the m
1 answer:
The magnetic field along the central axis of the cylinder will be <em>determined </em>using the formula given that all parameters are known
Generally, A magnetic field is also referred to as a vector field that shows the magnetic presence on electric charges and magnetic materials.
The formula for magnetic field is
Where
Therefore, the magnetic field along the central axis of the cylinder will be determined using the formula given that all parameters are known

Answer:
The minimum speed of the box bottom of the incline so that it will reach the skier is 8.19 m/s.
Explanation:
It is given that,
Mass of the box, m = 2.2 kg
The box is inclined at an angle of 30 degrees
Vertical distance, d = 3.1 m
The coefficient of friction,
Using the work energy theorem, the loss of kinetic energy is equal to the sum of gain in potential energy and the work done against friction.
W is the work done by the friction.
v = 8.19 m/s
So, the speed of the box is 8.19 m/s. Hence, this is the required solution.
