Answer:
The induced emf for this silver circle during this period of expansion is 0.0314 V.
Explanation:
Given that,
Initial radius = 0.075 m
Magnetic field = 1.5 T
Radius = 0.125 m
Time t =1.5 s
We need to calculate the induced emf for this silver circle
Using formula of emf
Put the value ino the formula
Hence, The induced emf for this silver circle during this period of expansion is 0.0314 V.

Height
Fill height
Angular speed
Generally the equation for Angular velocity is mathematically given by
Generally the equation for Liquid surface is mathematically given by
Therefore the liquid drop at center due to rotation is
Inertia is the tendency of an object to resist a change in its motion.
Answer:

Answer: 1
an object positioned at some height in a gravitational field
Explanation:
Gravitational potential energy of an object is the energy stored due to position of the object or position at certain height relative to zero position.
Gravitational potential energy can also be expressed as object position at some height above or below zero position in a gravitational field
I think 1 and 2 make sense. But 1 make more sense than 2
