Answer:
10 A
Explanation:
τ = Maximum torque of the loop = 9 mN
N = Number of turns in the loop = 50
a = side of the loop = 15 cm = 0.15 m
A = Area of the loop = a² = 0.15² = 0.0225 m²
B = magnitude of magnetic field = 0.800 T
i = magnitude of current in the loop
Maximum torque of the loop is given as
τ = N B i A
Inserting the values
9 = (50) (0.8) (0.0225) i
i = 10 A
Answer:
Option B
10.36 m/s
Explanation:
Using the first given equation, then velocity=distance/time
Since distance is provided as 200 m and time, t is 19.3 seconds then substituting these figures yields
v=200/19.3=10.3626943
Rounding off to 2 decimal places, then
v=10.36 m/s
Explanation:
The refraction is the change in the direction of light while travelling from the one medium to another due to having different speeds in different mediums.
To determine how much light gets refracted, it depends on the density of substance and the wavelength and the angle at which light enters the substance.
Light travels more slowly in denser medium than the rarer medium. The refractive index of glass is more than water or air. Light gets refracted more in this. When the light travels from rarer to denser then the light will get bend towards the normal. When the light travels from denser to rarer then the light will get bend away from the normal.
Glass is more denser than air or water. Water is more denser than the air. When light travels from air to glass then the light gets bends towards the normal. When the light travels from glass to the air then light gets bends away from the normal.
Therefore, the light gets refracted more in the glass than air to water.
