Answer:
The correct answer is the third
Force equals mass times acceleration
Explanation:
Newton's second law says that force equals mass times the acceleration of the body
F = m a
This is the most used way to solve problems
The correct answer is the third
Newton's third law states that forces always work in pairs, by action and reaction
Newton's first law states that an object per macerate with constant speed unless some force modifies this state.
The velocity, frequency and wavelength of a wave are related by:
v = fλ
v = 32 x 0.5
v = 16 m/s
The answer is B.
Yes. The main cause of polarization is by an external electric field. Polarization is characterized by an imbalance of charges where one end is more positive than the other end. When an electric field distorts the charges, there is a shift between the negative and positive poles. This causes the phenomenon called polarization.
They are easy to use and more reliable
Explanation:
Given that,
Wavelength of light, 
Angle, 
We need to find the slit spacing for diffraction. For a diffraction, the first order principal maximum is given by :
n is 1 here
d is slit spacing
So, the slit spacing is 
.
