Answer:
The solar cells transfer light energy to thermal energy.
When the battery is being charged up, chemical energy is transferred to electrical energy.
The motor is designed to transfer potential energy to kinetic energy.
Referring to the attached image below which represents the complete rock cycle, we will find that a marble can be formed when hot magma is cooled and crystallized.
Applying this to the given diagram, we will find that marble is most likely formed in position
C
The older students should be able to complete the puzzle in a shorter amount of time than the younger students
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
