Answer:
2.5 ft
Explanation:
minimum size of the mirror should be one half the person's height.
For this woman of 5 feet height, she would therefore need a mirror of length 2.5 feet
5ft ÷ 2 ft (half) = 2.5ft OR half of 5t is 2.5ft
The gravitational force between earth and moon will increase.
by F = GMm/r^2
F is inversely proportional to r^2
when r decrease, F will increase.
Answer:
Explanation:
From the question we are told that:
Speed of light 
Generally the equation for Average Speed is mathematically given by
Where
d=Distance between the Earth and the sun
Therefore
Since m and n is given in the form of
Therefore
I would use miles
Because miles will give you less of an answer
The correct answer is the reverse wave I took the test
