Answer:
The main driver of climate change is the greenhouse effect. Some gases in the Earth's atmosphere
The definition of matter is physical substance in general, as distinct from mind and spirit that which occupies space and possesses rest mass, especially as distinct from energy, which basically means that matter makes up the whole Earth and everything on it. <span />
Solution:
The relation between the potential difference and the electric field between the plates of the parallel plate capacitor is given by :

Differentiating on both the sides with respect to time, we get

Therefore, the rate of the electric field changes between the plates of the parallel plate capacitor is given by :


V/m-s
For n resistors in series, the equivalent resistance is given by the sum of the resistances:

In this problem, we have three resistors, so the equivalent resistance of the load is the sum of the resistances of the three resistors:
The train travells at he speed of 225 km/2.5h
now
225km=225000m
2.5 hr=150min=9000s
=>avg sp of train is=225000/9000s=25m/s
