Answer:
492.183 nm
Explanation:
x = Distance from the central maximum to the first minimum = 1.35 mm
l = Distance of screen = 2.13 m
d = Distance of gap = 0.705 mm
m = Order = 1
We have the relation
The wavelength of the light is 492.185 nm
Answer:
Explanation:
The mass of the man can be found by using the formula
f is the force
a is the acceleration
From the question we have
We have the final answer as
<h3>50 kg</h3>
Hope this helps you
Gasoline comes from petroleum, which is a fossil fuel. Petroleum, coal and natural gas (methane) are all made in the earth's crust from the bodies of plants and animals that died long ago. That's why they are called fossil fuels.
The sun provides the energy that all life needs to grow and reproduce. Therefore, fossil fuels can be considered a form of solar energy that has been stored in the bodies of living things, and then concentrated in hydrocarbon deposits in the earth's crust.
The fact is that all the energy on earth comes from the sun, directly or indirectly, except for nuclear energy, which comes from radioactive elements that were made in other stars that existed before the sun.

Answer:
4847.94844926 kg/m³
Explanation:
= Actual density of cube = 1900 kg/m³
= Density change due to motion
v = Velocity of cube = 0.92c
c = Speed of light = 
Relativistic density is given by
The cube's density as measured by an experimenter in the laboratory is 4847.94844926 kg/m³
If the input machine produces an
output of 80 Newtons, then the mechanical advantage is that it produces work. If
the required output must be 80 Newtons, then the input force is desirable
having 100 percent production of force even though it requires a large amount
of input to produce 80 Newtons of force.
