Answer:
579600J
Explanation:
Given parameters:
Height of the building = 828m
Weight of the man = 700N
Unknown:
Work done by the man = ?
Solution:
The work done by the man is the same as the potential energy expended.
Work done:
Work done = Weight x height = 700 x 828
Work done = 579600J
Answer:
θ = 1.591 10⁻² rad
Explanation:
For this exercise we must suppose a criterion when two light sources are considered separated, we use the most common criterion the Rayleigh criterion that establishes that two light sources are separated census the central maximum of one of them coincides with the first minimum of the other source
Let's write the diffraction equation for a slit
a sin θ = m λ
The first minimum occurs for m = 1, also field in these we experience the angles are very small, we can approximate the sin θ = θ
θ = λ / a
In our case, the pupil is circular, so the system must be solved in polar coordinates, so a numerical constant is introduced.
θ = 1.22 λ / D
Where D is the diameter of the pupil
Let's apply this equation to our case
θ = 1.22 600 10⁻⁹ / 0.460 10⁻²
θ = 1.591 10⁻² rad
This is the angle separation to solve the two light sources
Explanation:
Surface runoff: Excessive water collected on the land due to rains, storms, water melts and from other sources flows over the earth surface.
Transpiration: Moisture in the plants are absorbed by the roots and distributed in all the parts of plant. Moisture present in the underside of the leaves get converted into water vapors and releases in atmosphere
Evaporation : In this process , liquid state of water is converted into gaseous state of water that is water vapors.
Condensation: After evaporation , the water vapors rises up towards the sky. As they rise in the atmosphere the temperature decrease due which these water vapors stars getting converted into small water droplets. These small water drops combines with particles of dust , gas to form clouds
Precipitation: Water released from the clouds in the form of rain.
