A
Explanation:
or else u would get a muscle pull
When light passes from one medium to another at an angle, it may refract, or bend, according to Snell's law:
n₁sin(θ₁) = n₂sin(θ₂)
n₁ = index of first medium, θ₁ = angle of incidence, n₂ = index of second medium, θ₂ = angle of refraction
Given values:
n₁ = 1.33 (water), θ₁ = 45.0°, θ₂ = 40.3°
Plug in and solve for n₂:
1.33sin(45.0°) = n₂sin(40.3°)
n₂ = 1.454
I looked up this value on the HyperPhysics indices of refraction table... The index we calculated is closest to 1.46, which is that of fused quartz.
maximum height upto which water will reach is given as
now we know that as water will reach the top its speed will become zero
now if water is ejecting through nozzle then we will have
Now if water is ejecting out without nozzle
then we will have
Answer:
The value is
Explanation:
From the question we are told that
The time taken to travel to the planet from earth is
The time to be spent on the ship is
Generally speed can be obtained using the mathematical relation represented below
The 2 in the equation show that the trip is a round trip i.e going and coming back
