Answer:
v = 13.79 m/s
Explanation:
given,
mass of ball = 110 g
height = 11 m
ball is released from = 1.3 m
minimum speed = ?
using conservation of energy
Potential energy is conserved in the form of kinetic energy
v = 13.79 m/s
I am assuming you know the relation obtained between slit width, distance of screen from slits, distance of interference pattern obtained on the screen from the center and the wavelength of monochromatic light used in Young's Double Slit experiment.
λ =
λ ~ 1.97 ×10⁻⁷m
Answer:
Explanation:
Given that,
Lightning flashes one mile (1609 m) away from you.
We need to find the time it take the light to travel that distance. Let the time be t. We know that,
speed = distance/time
So, the required time is
