Which statement best describes who the period and frequency of electromagnetic was change between gamma rays and microwaves?
2 answers:
Answer : <em> The period increases and the frequency decreases</em>.
Explanation :
Gamma rays are the rays having frequency( ) greater than
and frequency of microwave lie between 300 MHz to 300 GHz.
Since,
So, as we move from gamma rays to microwaves the energy increases because frequency is increasing.
Also, Time period
We can say that as the time period increases, frequency decreases.

Explanation:
To answer the question, we just need to consider the motion along the horizontal direction.
The component of the initial velocity of the ice skater along the x-direction is:
where u = 2.25 m/s is the initial velocity and is the angle.
The component of the final velocity of the ice skater along the x-direction is
where u = 4.65 m/s is the final velocity and is the angle.
The acceleration along the x-direction is given by
where
t = 120 s is the time
Substituting,
Answer:
Explanation:
Centripetal acceleration is calculated by the following equation:
Where:
is the Earth's orbital speed
is the orbital radius
