Explanation:
It is given that,
The horizontal speed of a cliff diver,
It reaches the water below 2.00 s later, t = 2 s
Let is the distance where the diver hit the water. It can be calculated as follows :
Let is the height of the cliff. It can be calculated using second equation of motion as follows :
So, the cliff is 19.6 m high and it will hit the water at a distance of 19.6 m.
Answer:
t = 103.45 n m
Explanation:
given,
refractive index of cornea = 1.38
refractive index of eye drop = 1.45
wavelength of refractive index = 600 nm
refractive index of eye drop is greater than refractive index of cornea and the air.
Formula used in this case
for constructive interference
At m = 0 for the minimum thickness, so
t = 103.45 n m
the minimum thickness of the film of eyedrops t = 103.45 n m
Answer:
Explanation:
given,
mass of spaceship(m) = 8600 Kg
Mass of earth = 5.972 x 10²⁴ Kg
position of movement of space ship
R₁ = 7300 Km
R₂ = 6700 Km
the kinetic energy of the spaceship increases by = ?
Increase in Kinetic energy = decrease in potential energy
