Given
Train travels towards south with a velocity if
Rain makes an angle of with vertical
If an observer sees the drop fall perfectly vertical i.e. horizontal component of rain velocity is equal to train velocity
suppose is the velocity of rain with respect to ground then
Therefore velocity of rain drops is 27.36 m/s

b) 0.00105 °C^-1
Explanation:
Given that
Length of the cylinder, L = 1.5 m
Radius of the cylinder, r = 0.25 cm
Voltage across the rod, V = 15 V
I• at Temperature T• = 20° C is 18.5 A
I at Temperature T = 90° C is 17.2 A

Answer:
The thickness is
Explanation:
From the question we are told that
The wavelength is
The first order of the dark fringe is
The second order of dark fringe considered is
Generally the condition for destructive interference is mathematically represented as
Here y is the path difference between the central maxima(i.e the origin) and any dark fringe
So the path difference between the 16th dark fringe and the 6th dark fringe is mathematically represented as
