Answer:
The time constant is 1.049.
Explanation:
Given that,
Charge
We need to calculate the time constant
Using expression for charging in a RC circuit
Where, = time constant
Put the value into the formula
Hence, The time constant is 1.049.
Isla made a diagram to compare X-rays and radio waves.
1 answer:
A: Has a higher frequency --> X-rays
B: Travels at the same speed --> Both
C: Has a longer wavelength --> Radio waves
Explanation:
Electromagnetic waves are waves consisting of oscillations of electric and magnetic field in a direction perpendicular to the direction of motion of the wave.
Electromagnetic waves travel at the speed of light () in a vacuum, and they are transverse in nature (the direction of vibration is perpendicular to the direction of propagation).
Electromagnetic waves are classified into different types according to their wavelength and frequency. In order from shortest to longest wavelength (and so, from highest to lowest frequency, since frequency is inversely proportional to the wavelength), we have:
Gamma rays
X-rays
Ultraviolet radiation
Visible light
Infrared radiation
Microwaves
Radio waves
Therefore, we can no says that:
X-rays: has a higher frequency than Radio waves
Radio waves: have a longer wavelength than x-rays
Both: they travel at the same speed
Therefore, the correct pairing is:
A: Has a higher frequency --> X-rays
B: Travels at the same speed --> Both
C: Has a longer wavelength --> Radio waves
