Here is your answer
b) 
REASON :
We know that
Velocity= Frequency× Wavelength
So,
Frequency= Velocity/wavelength
Here,
V= 3× 10^8 m/s
Wavelength= 2×10^-3 m
Hence,
Frequency= 3×10^8/2×10^-3
= 3/2 × 10^11
= 1.5× 10^11 Hz
HOPE IT IS USEFUL
I hope it is clearly visible.. Velocity of the center of mass of 2-ball system is - 11.54m/s. Minus indicates, velocity direction is in downward direction.
Answer:
The inner planets (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars . the outer planets, Jupiter, Saturn, Uranus and Neptune
Explanation:
Answer:
It loses electrons.
Explanation:
Electrons have a negative charge meaning ,the less electrons there are in an object the stronger the positive charge is.
Newton’s first law is motion. For example, an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
