The way their suppose to do it
<h3>
Answer: A) 3 pronged cord</h3>
Explanation:
One prong is known as the hot wire, where the electricity comes in, while the second prong is the neutral wire and electricity leaves. Recall that a circuit must be made for electrons to flow. This means that electrons enters your house through the transmission wires and then the electrons leave along the same lines they entered (just along a different wire).
This set up describes a 2 pronged cord. Adding a third prong allows for a grounding to happen. In the event of an electrical surge, when too many electrons are flowing, disaster is likely to happen without some kind of safety features. The grounding prong allows electrons to seek the ground. You can think of it like a drain in a bathtub when too much water gets in the tub.
Answer:
Option D.) 5.0 x 10^-4m
Explanation:
Data obtained from the question include:
f (frequency) = 6 x 10^11 Hz
v (velocity) = 3.00 x 10^8 m/s
λ (wavelength) =?
Using the equation v = λf, the wavelength can be obtained as illustrated below:
v = λf
λ = v/f
λ = 3.00 x 10^8/6 x 10^11
λ = 5 x 10^-4m
Therefore, the wavelength of the beam of the electromagnetic radiation is 5 x 10^-4m
Units is the correct answer
Why does this same one keep popping up what ever I think it is 65 a and c are definitely not it so if your going to guess go with b or d but I’m purée sure it’s d
