Answer:
the emf will be ![2.4(1.20\times 10^{-2}+13.4\times 10^{-5}t^3)](https://tex.z-dn.net/?f=2.4%281.20%5Ctimes%2010%5E%7B-2%7D%2B13.4%5Ctimes%2010%5E%7B-5%7Dt%5E3%29)
Explanation:
We have given radius of the coil r = 3.6 cm = 0.036 m
So area ![A=\pi r^2=3.14\times 0.036^2=0.0040m^2](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E2%3D3.14%5Ctimes%200.036%5E2%3D0.0040m%5E2)
Number of turns N = 600
Emf is given by ![e=N\frac{d\Phi }{dt}](https://tex.z-dn.net/?f=e%3DN%5Cfrac%7Bd%5CPhi%20%7D%7Bdt%7D)
![e=N\frac{d\Phi }{dt}=NA\frac{dB}{dt}=600\times 0.0040\times d\frac{1.20\times 10^{-2}t+3.35\times 10^{-5}t^4}{dt}=2.4(1.20\times 10^{-2}+13.4\times 10^{-5}t^3)](https://tex.z-dn.net/?f=e%3DN%5Cfrac%7Bd%5CPhi%20%7D%7Bdt%7D%3DNA%5Cfrac%7BdB%7D%7Bdt%7D%3D600%5Ctimes%200.0040%5Ctimes%20d%5Cfrac%7B1.20%5Ctimes%2010%5E%7B-2%7Dt%2B3.35%5Ctimes%2010%5E%7B-5%7Dt%5E4%7D%7Bdt%7D%3D2.4%281.20%5Ctimes%2010%5E%7B-2%7D%2B13.4%5Ctimes%2010%5E%7B-5%7Dt%5E3%29)
So the emf will be ![2.4(1.20\times 10^{-2}+13.4\times 10^{-5}t^3)](https://tex.z-dn.net/?f=2.4%281.20%5Ctimes%2010%5E%7B-2%7D%2B13.4%5Ctimes%2010%5E%7B-5%7Dt%5E3%29)

Answer:
A fan pushes hot air out of a vent and into a room. The hot air displaces cold air in the room, causing the cold air to move closer to the floor.
The hot air displacing the cold air is an example of transfer by
Explanation:
c: a combination of longitudinal and transverse
Explanation:
Surface waves are a combination of longitudinal and transverse waves. These waves causes destruction after an earthquake on the ground surface.
- The surface waves are both rayleigh and love waves.
- Rayleigh waves and love waves are responsible for the destruction caused by an earthquake.
- They both have a unique characteristic of being propagated longitudinally and transversely away from their source.
- The spread compressional disturbance and undulating ones at the same time on the earth surface.
- These waves are seismic waves.

your answer is.....
D. have a large atomic radius
although they also increase going from left to right so if D is incorrect, B might be your answer. it depends on context of the lesson.
