Answer:
The average speed is 22.5 km/hr and displacement is zero.
Explanation:
Given that,
Distance of one side = 45 km
Time = 4 hrs
We need to calculate the average speed
Using formula of average speed
Where, D = total distance
T = total time
Put the value into the formula
Displacement will be zero because the journey ends where the journey stated.
Hence, The average speed is 22.5 km/hr and displacement is zero

When light travels from a medium with higher refractive index into a medium with lower refractive index, there is a maximum angle (called critical angle) for which all the light is reflected, so there is no refraction.
The value of the critical angle is given by:
when n1 is the refractive index of the first medium, while n2 is the refractive index of the second medium. In our case, n1=1.33 (the water) and n1=1.00 (the air). Putting numbers in, we get

Answer:
e. The net magnetic flux in this case would be equal to zero.
Explanation:
As per Gauss law of magnetism we need to find the net magnetic flux through a closed loop
here we know that net magnetic flux is the scalar product of magnetic field vector and area vector
so here we have
= net magnetic flux
since we know that magnetic field always forms closed loop so if we find the integral over a closed loop
then in that case the value of the close integral must be zero
so correct answer would be
e. The net magnetic flux in this case would be equal to zero.
