Answer:
d. 332 V
Explanation:
Given;
number of turns in the wire, N = 40 turns
area of the coil, A = 0.06 m²
magnitude of the magnetic field, B = 0.4 T
frequency of the wave, f = 55 Hz
The maximum emf induced in the coil is given by;
E = NBAω
Where;
ω is angular velocity = 2πf
E = NBA(2πf)
E = 40 x 0.4 x 0.06 x (2 x π x 55)
E = 332 V
Therefore, the maximum induced emf in the coil is 332 V.
The correct option is "D"
d. 332 V
The correct answer is <span>(a) biomass
Biomass is carbon based just like coal and oil which are bad because they're fossil fuels. However, unlike them, biomass is renewable, which is good, but is also bad for the environment.</span>
The correct answer to this qustion is velocity and time
A- 85m per second
B- 85 sdcounds
Answer:
10
Explanation:
Each time you want to move up the scale, the number is multiplied by 10. The opposite is true when moving down; you must divide by 10.
