Axial Tilt and Sun Energy
This axial tilt means that during the Earth's journey around the sun the poles receive varying amounts of sunlight. The equator, however, receives relatively consistent sunlight all year. The consistency of energy means the equator's temperature stays relatively constant all year.
Answer:

Explanation:
As we know that rate of change in flux will induce EMF
So here we can

now we have

now we also know that induced EMF is given by



now plug in all values in it


Answer:
![W=-\int_{0}^{50}[150-0.5y]dy](https://tex.z-dn.net/?f=W%3D-%5Cint_%7B0%7D%5E%7B50%7D%5B150-0.5y%5Ddy)
Explanation:
the integral for the work is:

the work is against the gravitational force. While the coal is going up, M(y) is changing due to the length of the cable is lower. We can describe this by using the following formula

Thus , the integral for the work is:
![W=-\int_{0}^{50}[150-0.5y]dy](https://tex.z-dn.net/?f=W%3D-%5Cint_%7B0%7D%5E%7B50%7D%5B150-0.5y%5Ddy)
hope this helps!!
Answer:
3.8 km
Explanation:
Eastern Side Bus
Velocity = 20m/s
Covers distance in 2 min (120sec) = 20×120 = 2400m = 2 km
Western Side Bus
Velocity = 15m/s
Covers distance in 2 min (120sec) = 15×120 = 1800m = 1.8 km
Separation Distance = 2+1.8 = 3.8 km
