Answer:
3.84x10^14Hz
Step-by-step explanation:
From the question, the following were obtained:
Velocity = 3x10^8m/s
Wavelength = 7.80x10^-7
Frequency =?
Frequency = Velocity /wavelength
Frequency = 3x10^8/7.80x10^-7
Frequency = 3.84x10^14Hz

Answer C will be your best option here.
Answer:
1km per minute
Step-by-step explanation:
Given the table in the picture :
The average rate of change over the interval from 8 to 15 minutes will be :
Change in distance / change in time
Change in distance between 8 and 15 minutes :
Distance d1 at 8 minutes t1 = 7km
Distance d2 at 15 minutes t2 = 14km
Average rate of change = (d2 - d1) / (t2 - t1)
Average rate of change = (14 - 7)km / (15 - 8)min
Average rate of change = 7km / 7minutes
Average rate of change = 1km per minute
