Explanation:
Answer:
The rate of change of the shadow length of a person is 2.692 ft/s
Solution:
As per the question:
Height of a person, H = 20 ft
Height of a person, h = 7 ft
Rate = 5 ft/s
Now,
From Fig.1:
b = person's distance from the lamp post
a = shadow length
Also, from the similarity of the triangles, we can write:

Differentiating the above eqn w.r.t t:
Now, we know that:
Rate = 
Thus
When oxygen is present, cellular respiration produces carbon dioxide, water, and energy in the form of ATP.
When oxygen is not present, cellular respiration produces lactic acid or alcohol.
Hope this helps! :)
Answer:
or 
23.4843749996 m
Yes
Explanation:
E = Electric field = 
c = Speed of light = 
m = Mass of proton= 
q = Charge of electron = 
Acceleration is given by

Dividing by g

The acceleration is
or 

The distance is 23.4843749996 m
The gravitational field is very small compared to the electric field so the effects of gravity can be ignored.
