Answer:
f = 5.63 x 10¹⁴ Hz
Explanation:
Given,
speed of light, c = 3 x 10⁸ m/s
wavelength,λ = 533 n m = 5.33 x 10⁻⁷ m
frequency, f = ?
using formula of frequency

c is the speed of light

f = 5.63 x 10¹⁴ Hz
hence, the frequency of the light is equal to f = 5.63 x 10¹⁴ Hz
Answer:
The woman's average velocity during the trip is 36.2 miles/hour.
Explanation:
Velocity can be define as the displacement of an object per time. It is a vector quantity, and measured in m/s.
i.e velocity = 
From the given question,
Displacement = 
= 
= 
= 425
The displacement of woman is 425 miles.
velocity = 
= 36.1702 miles/hour
The woman's average velocity during the trip is 36.2 miles/hour.
