Radio waves have longer wavelengths and lower frequencies than microwaves.
infrared is longer wavelengths and lower frequencies than UV light
Answer:
At twice the distance, the strength of the field is e/4
Explanation:
F = the strength of an electric field.
F is inversely proportional to the squared distance from the point charge.
mathematically,
F = k(e/d²)
hence, if d is doubled,keeping other forms constant
F = e/4,
Answer:
D
Explanation: this is why they have so much more energy released
What happens when the light hits the glass depends on what it was in before it hit the glass.
WHILE it's in the glass, the speed of light doesn't change.
Answer:
The magnitude of change in momentum of the ball is 
and impulse is also
Explanation:
Given:
Velocity of a pitched ball 
Velocity of ball after impact 
From the formula of change in momentum,
Here mass is not given in question,
Mass of ball is 
Change in momentum is given by,
Magnitude of change in momentum is
And impulse is given by
So impulse and
Therefore, the magnitude of change in momentum of the ball is and impulse is also
