As we know that,
<h3>F = ma</h3>
- F is the Force applied
- M is the Mass
- A is the Acceleration
<u>According</u><u> </u><u>to</u><u> </u><u>the question</u><u>, </u>
F = 20 × 2
F = 40 N
<h3>Hence :-</h3>
Force applied is 40 N

- Third Equation of motion
- v² - u² = 2as
Number of rulings per centimeter for the grating 4.5 x 10^3 grooves/cm
Given:
wavelength of light = 635.00 nm
angle of first order = 38.0∘
To Find:
Length of slits marked on grafting
Solution: Grafting and budding are horticultural techniques used to join parts from two or more plants so that they appear to grow as a single plant
We use the grating equation dsinθ = mλ
d = mλ/sinθ
d = 1 x 635x10^-7 m/sin 38.0∘
d = 2189.6 x 10^-7 m
Thus the grating gauge is
1/d = 0.00045 x 10^7 = 4.5 x 10^3 grooves/cm
So, number of rulings per centimeter for the grating 4.5 x 10^3 grooves/cm

3 ways would be they are used for movement, form structure and carry out reactions, processes, and cells
Answer:
b . is zero.
Explanation:
An Equipotential surface is the one that has electric potential same throughout the surface. The formula for work done in an electric field is given by
dW= qdV
Now, in an Equipotential surface dV= 0.
Hence the work done in moving a charge from one place to the other in an electric field is zero.
The correct answer is D.
A nucleon<span> is one of either of the two types of subatomic particles (neutrons and protons) which are located in the nucleus of atoms.

The total number of nucleon in the nucleus of an atom gives you an idea about the mass of that atom. In fact, one may refer mass number as nucleon number.
Simply put, nucleons are the particles that make nucleus of an atom and are held up together inside the nucleus due to nuclear force.
