Answer:
Explanation:
Force between two charges is given by the following expression
F = 
Q₁ and Q₂ are two charges and d is distance between two.
.1 =
If Q₁ becomes three times , force will become 3 times . Hence force becomes .3 N in the first case.
Force F = .3 N
If charge becomes one fourth , force also becomes one fourth .
F= 
= .025 N.
Answer:
In order for the eye to see an object, light from the object must be reflected to your eye.
Answer:
2210.91 N
Explanation:
f = v/∧ = 1/2 √ T/ μ
where f= 28.1 Hz , T= tension ,
L= 2m
mass density = μ = 350÷1000/2.00
= 0.175kg/m
from f = 1/2L √ T/ μ
make T the subject of the formula
T= (f×2L)² ₓ μ
T= (28.1×2×2)² ×0.175
T=12633.76×0.175
=2210.91 N
By Newton's second law, we have
So, in order to give a 0.15kg body an acceleration of 40m/s^2, you need a force of
B is true, however that is not a way in which conserving and recycling paper helps manage energy sources...
