<span>The correct answer is: (D) Generator
Explanation:
In wind-powered systems, the wind energy turns the blades around the rotor of a wind turbine. That rotor is connected to a generator that generates electricity. In other words, the kinectic energy of the wind is converted into electrical energy by using the generator in the wind-powered systems.</span>
Answer:
R = 1.2295 10⁵ m
Explanation:
After reading your problem they give us the diameter of the lens d = 4.50 cm = 0.0450 m, therefore if we use the Rayleigh criterion for the resolution in the diffraction phenomenon, we have that the minimum separation occurs in the first minimum of diffraction of one of the bodies m = 1 coincides with the central maximum of the other body
θ = 1.22 λ / D
where the constant 1.22 leaves the resolution in polar coordinates and D is the lens aperture
how angles are measured in radians
θ = y / R
where y is the separation of the two bodies (bulbs) y = 2 m and R the distance from the bulbs to the lens
R =
let's calculate
R =
R = 1.2295 10⁵ m
It holds A. Less water than when it is warmer.
Answer:
21 miles
Explanation:
3 miles an hour for 7 hours
Its simply 7m*3m/hr=21 miles
Calculate the kinetic energy of an 86-kg scooter moving at 18 m/s?
K.E. = (1/2)mv^2
K.E. = (1/2)86 * 18^2
K.E. = (Answer Unit) =====> J
M = 86kg
V = 18 m/s
Significant Figures ======> 6
Answer: ======>
KE = 13932 J
Show work:
1/2 * 86 * 18^2
(1/2)86 * 18^2
Remove Parenthesis:
a = a
1/2 * 86 * 18^2
Multiply Fractions:
a * b/c = a * b/c
= 1 * 86 * 18^2/2
Multiply the numbers:
1 * 86 = 86
18^2 * 86/2
Divide the numbers:
86/2 = 43
18^2 * 43
18^2 = 324
43 * 324
Multiply the numbers:
43 * 324
13932
Therefore, Your answer is KE = 13932 J
Hope that helps!!!! : ) sorry for the long explanation!!!
