Total energy will remain the same
Explanation:
Given that,
Radius of the circular loop, r = 3.5 cm = 0.035 m
(a) During a 0.12-s time interval, the magnitude of the field increases uniformly from 0.2 T to 0.5 T. Due to the change in the magnetic field, an emf will induced in it. The magnitude of induced emf is given by :

So, the magnitude of the emf induced in the loop during the time interval is
.
(b) The negative sign shows that the direction of induced emf in the loop is in anitclockwise direction.
Answer:
There are 1.806 X 1024 molecules in 3 moles of CO2. This concept is similar to counting 144 eggs and dividing by 12 to get the number of cartons.
Yes, many professional athletes will take dance classes to improve their skills. Such as football players to improve their footwork and use other muscles they wouldn't use while doing just push ups.
1000 m/s
You have the wavelength and frequency, you just need to solve for velocity. You can do this by multiplying each side of the equation by frequency.
