Answer:
18.66 ft/s
Step-by-step explanation:
The distance between you and the elevator is given by:
The rate of change for the distance between you and the elevator is given by:
Applying the chain rule:
Therefore, at x=300 and y = 500, dy/dt is:
The elevator is descending at 18.66 ft/s.
Answer:
l
Step-by-step explanation:
Step-by-step explanation:
The frequency of a radio wave that has a wavelength of 3000m is 100 kHz
(a) Wavelength = 500 m
We know that,
(b) Frequency, f = 800 kHz
Hence, this is the required solution.
