9.90 gallons of gas at 27.77 miles per gallon
frequency's unit is Hz which mean cycles per second
given frequency * wavelength = speed of wave
speed of light = 3x10^8 m/s
wavelength = 680nm = 680x10^-9 m
frequency * 680x10^-9 m = 3x10^8 m/s
frequency = 3x10^8 / 680x10^-9
= 4.41x10^14 Hz
= 441x10^12 Hz
= 441 THz
which is the frequency for red light
Answer:
D
Explanation:
We need to know about materials cost and how things are produced how much they pay their workers things like that to understand the comparative advantages
I think it’s better for him to ask you but there is nothing wrong with asking him, hope ur prom will be fantastic!
