Answer:
e= 0.440 mV(millivolt)
Explanation:
Given Magnetic field B= 0.50T
Δt= 1.6sec
⇒
e= 0.440 mV(millivolt)
The New England Merchants Bank Building in Boston is 152 m high. On windy days it sways with a frequency of 0.15Hz , and the acc
eleration of the top of the building can reach 2.5% of the free-fall acceleration, enough to cause discomfort for occupants.
What is the total distance, side to side, that the top of the building moves during such an oscillation?
