Answer:
The time is 0.563 ns.
Explanation:
Given that,
Index of refraction of glass = 1.41
Distance = 12.0 cm
Angle = 33.0°
We need to calculate the refraction angle
Using Snell's law
put the value into the formula
We need to calculate the velocity of beam in glass
Using formula of velocity
Put the value into the formula
We need to calculate the time
Using formula of distance
Hence, The time is 0.563 ns.
Answer:
All of the above
Explanation:
The magnitude of the magnetic force on a current-carrying wire held in a magnetic is given by the equation
Where B = Strength of the magnetic field
I = The current carried by the wire
l = length of the wire in the magnetic field
θ = Angle between the wire and the magnetic field
Based on the relationship written above, the magnitude of the magnetic force on the current - carrying wire in the magnetic field depends on the strength of the magnetic field (B), length of the wire(l), current in the wire (I).
All the options are correct.
