Your answer is most likely:
<span>B) They are protective of their owners. </span>
Answer:
Explanation:
When two coherent light beams travel different paths and arrive at a point , there will be difference in the length of path travelled by them . If this difference is zero then both will reinforce each other and their brightness will add up . Hence there will be constructive interference .
If their path difference is not zero but it is equal to odd multiple of their half wavelength like λ / 2 , 3 λ / 2 , 5 λ /2 , 7 λ /2 etc , then instead of reinforcing each other , they will destroy each other . This is called destructive interference . As a result of it , darkness will prevail at the point where they meet or interfere.
<span>C. It is the difference in electrical potential energy between two places in an electric field.</span>
The answer is B
I used these equations then i putted it together.
Charge = number of ( electron or proton ) x charge of ( electron or proton )
Force = k x (q1 q2)/r²
Answer:
The answer to your question is: F = 924 N
Explanation:
Data
v = 28 m/s
m = 66 kg
d = 56 cm
F = ?
Formula
v = d/t
a = v/t
F = ma
Process
t = d/v = 56 / 28 = 2 s
a = v/t = 28 / 2 = 14 m/s²
F = 66 (14) = 924 N
