Answer:
d
Explanation:
Solution:-
- The Quantity of theory of money states:
M * V = P * Y
Where,
M = Money supply
V = Velocity of money exchange
P = The price level
Y = Real GDP
- By re-arranging the formula and solving for "V" we have:
V = P*Y / M
- The expression on right hand side increases if exchange of dollars increases.
Answer:
Explanation:
Force due to charges 1.75 and 5 nC is given below
F =K Q₁Q₂ / d²
F₁ =
F₁ = 10.8 X 10⁻⁵ N . It will at in x direction.
Force due to other charge placed at origin
F₂ =
F₂ = 3.5 x 10⁻⁵ N.
Its x component
= F₂ Cos θ
= 3.5 x 10⁻⁵ x 3.9/ 4.74
= 2.88 x 10⁻⁵ N
Its y component
F₂ sin θ
= 3.5 x 10⁻⁵ x 2.7/4.743
= 1.99 x 10⁻⁵ N
Total x component
= 10.8 X 10⁻⁵ +2.88 x 10⁻⁵
= 13.68 x 10⁻⁵ N.
Magnitude of total force F
F² = (13.68 x 10⁻⁵)² + (1.99 x 10⁻⁵ )²
F = 13.82 X 10⁻⁵ N
Direction θ with x axis .
Tanθ = 1.99/ 13.68
θ = 8 °
Answer:
V = 0
Explanation:
To find the potential at the middle of the two charges with opposite signs, you use the following formula:
(1)
where you have used the fact that the charges are the same and the distances are the same.
The electric potential is zero at the point in the middle of the two charges
The answer would be B.Moisture,unstable air,and a way for the surface air to rise
