An example of an energy conversion that produces an unwanted form of energy is mixing acids with water.
Answer: 0.66 V
Explanation:
Given
Magnetic field, B = 0.963 T
Instantaneous rare = 74.5 cm/s = 0.745 m/s
radius, r = 14.7 cm = 0.147 m
We will use the formula
emf = dΦ/dt
emf = d(BA)/dt
emf = d(Bπr²)/dt
if B is constant, then we can say
emf = Bπ d(r²)/dt on differentiating, we have,
emf = Bπ (2r dr/dt)
emf = 2πrB dr/dt substituting each values, we have
emf = 2 * 3.142 * 0.147 * 0.963 * 0.745
emf = 0.66 V
Therefore, the induced emf in the loop at that instant is 0.66 V
Answer:
summer June 21 is the answer
Answer:
option A
Explanation:
The meteor shower is the celestial activity in which meteors are observed to radiate or originate from one point.
Meteors are nothing but dust or ice from the trails of comets. Most of the meteors are less than the size of the sand particle.
We will see comet shower when we earth will cross the orbit of the comet.
Hence, the correct answer is option A
