Answer:Four spheres of earth are:1)Lithosphere(land) 2)Hydrosphere(water) 3)Biosphere(living things) 4)Atmosphere(air).
Energy and matter flow through Earth's four spheres.Energy flows through the atmosphere and hydrosphere mostly by convection.The continuous cycling of matter and energy through earth's system makes life on earth possible .Others are driven by energy from the sun.

Electricity is the flow of electrical power or charge. Everyday, we use electricity to do many jobs for us from lighting and heating/cooling our homes, to powering our televisions and computers. We get electricity from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources. Electricity can be broken down into some very simple, natural elements. The biggest of which is the atom. Atoms are everything.
Not only that we are made of atoms, but atoms are everywhere. It's a known fact that almost anyone should know.
Answer:
d is zero (0)
Explanation:
ψ(x)=ce^κx+de^−κx
Let say x = - 1000
We have something like
ce^κ* -1000 = approximately zero
Where we assume k to be 1
C becomes zero as it tend to negative infinity
But
If k is 1
de^−1* 1000 =d * 2 * 10^434
To have a zero function d = 0
So 0 * 2 * 10^434 = 0
