<u>Answer:</u>
Alternating Current (AC).
<u>Explanation:</u>
The current that is provided to consumers in the United States changes direction sixty times a second. This household current is called alternating current (AC). Alternating current is much more efficient in transmitting electricity than direct current is. In order to produce this current, it is found in Alternating Current Power Plants.
Answer:
5.234 m/s^2
Explanation:
Weight (force due to gravity) is proportional to the acceleration due to gravity. For some g' on MPAW, the relation is ...
g'/g = (2714 N)/(5185 N)
g' = g(2714/5185) = (10 m/s^2)(2714/5185)
g' ≈ 5.234 m/s^2
Answer:
E = 2.17 x 10⁻² V/m
Explanation:
First we will find out the current density by using the formula:
J = I/A
where.
J = Current Density = ?
I = Current = 5.5 A
A = Cross-Sectional Area = πr² = π(1.5 x 10⁻³ m)² = 7.068 x 10⁻⁶ m²
Therefore,
J = 5.5 A/7.068 x 10⁻⁶ m²
J = 0.778 x 10⁶ A/m²
Now, we calculate the magnitude of applied field:
E = ρJ
where,
E = Magnitude of applied field = ?
ρ = resistivity of Aluminum = 2.8 x 10⁻⁸ Ω.m
Therefore,
E = (2.8 x 10⁻⁸ Ω.m)(0.778 x 10⁶ A/m²)
<u>E = 2.17 x 10⁻² V/m</u>
Answer:
a) 2232nm
b) 2511nm
Explanation:
a) To find the path difference Δl you use the following formula:
m: order of a bright fringe
λ: wavelength of light = 558nm
for m=4:
b) The path difference for the case of destructive interference you have:
m: order of a dark fringe
for m=4:
Given:
s(distance)= 20 meters
F(force)=200N
Now we know that
work done= Force applied x distance
Substituting the given values in the above formula we get
Work done= 20 x 200= 4000J
