Answer: D.ultraviolet rays, visible light, infrared radiation, microwaves.
Explanation:
Shorter wavelength means higher frequency and higher energy.
Thus, the correct sequence of electromagnetic waves from shorter wavelength to longer wavelength is:
D.ultraviolet rays, visible light, infrared radiation, microwaves.
<u>Ultraviolet rays have shorter wavelength (about 380 nm) and high energy. </u>
<u>Visible light has wavelength: 380 nm to 700 nm</u>
<u>Infrared wavelength: 700 nm to 1 mm</u>
<u>Microwave wavelength: 1 mm to 1 m</u>
The correct answer for the question that is being presented above is this one:
Phi = BAsin(theta)
<span>1. Phi(i) = BA </span>
<span>2. Phi(f) = 0 </span>
3. EMF = N(phi(i)-phi(f))/deltat
Here are the follow-up questions:
<span>1. What is the total magnitude Phi_initial of the magnetic flux through the coil before it is rotated? </span>
<span>2. What is the magnitude Phi_final of the total magnetic flux through the coil after it is rotated? </span>
<span>3. What is the magnitude of the average emf induced in the coil?</span>
Radio waves in a vacuum travel at the speed of light because they are a type of electromagnetic radiation like a light has been measured as traveling at 3×10^8 m/s in a vacuum.
Charged particles that are accelerating, like time-varying electric currents, are what produce radio waves. Radio and television signals are transmitted using radio waves, and microwaves used in radar and microwave ovens are also radio waves. Radio waves are emitted by a lot of celestial bodies, including pulsars. High RF exposure levels have the potential to heat biological tissue and raise body temperature. The body's inability to handle or remove the extra heat that could be generated by high RF exposure in humans could result in tissue damage.

Answer:
zero
Explanation:
although force was applied as long as there's no movement ,no work has been done
mathematically;work=force×distance
work=2700×0
work=0J
