Answer:
I will answer this in English, we can translate it to:
Why if you charge a mate by an amount of time you are not doing work?
This happens because work is defined as the displacement done by a force:
W = d*F
where W is work, d is the distance, and F is the force.
This means that the amount of time that you are charging your mate does not affect the mechanical work, the only time that you are doing work is when you are lifting him.
Answer:
The wavelength of the light is 562.5 nm
Solution:
As per the question:
Order, n = 1
Slit separation, d =
Distance from the bright fringe, y = 0.18 m
Distance between the screen and the grating, D = 0.8 m
Now,
We know from the eqn for diffraction:
n = 1
(1)
Also,
For very small angle, :
≈
Using the above value in eqn (1):
Answer:
Density of rock will be equal to
Explanation:
It is given that mass of the rock
Volume displaced bu rock
We have to find the density of rock
Density is equal to ratio of mass and volume
Therefore density of rock
So density of rock will be equal to
Answer:
It includes the preserved soft tissue of an organism
Answer:
a bowling ball placed on the top shelf of a closet.
Explanation:
Potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.
Mathematically,
Potential energy, PE = M × g × h
