Answer:
The number of turns in the secondary coil is 48.
(B) is correct option.
Explanation:
Given that,
Number of turns on primary coil= 1000
Primary voltage = 2500 V
Secondary voltage = 120 v
We need to calculate the turns in the secondary coil
Using relation between voltage and number of turns in primary and secondary coil
Put the value into the formula
Hence, The number of turns in the secondary coil is 48.
The answer is polarization. It is just like when you are on a boat and use polarized glasses so the water wont reflect into your eyes it also intensifies the color of the water so you can see better into the water.
example: you cant see any fish because glare from the sun, put on polarized glasses and now you can see fish up to 30 feet deep.
Answer: wavelength is equal to 150 m
Explanation: To solve for the wavelength we will use the formula of frequency which is the ratio of wave speed per unit wavelength and derive to find wavelength.
wavelength = wave speed / frequency
= 1500 m/s / 10 Hz
= 150 m
Answer:
Yellow
Explanation:
Yellow light has lesser energy than blue light, this means blue light has a much smaller wavelenght. For the width of the central band to be greater, the wavelenght has to be more, and yellow light has a much larger wavelenght
They move in a waves motion
