Answer:
The answer is "
"
Explanation:
Z=2, so the equation is 
Calculate the value for E when:
n=2 and n=9
The energy is the difference in transformation, name the energy delta E Deduct these two energies
In this transition, the wavelength of the photon emitted is:



The global warming is because of the car pollution was the fire in the forest it makes the air one and the warm air grocery Pacific side which makes me glacier it mostly glacier and breaks down two bases and the rising of the water makes the global warming too much so people are trying to use this card and try to use cycles because of global warming .

Answer:
F=m(a) 3.111
Explanation:
So to find the acceleration you would have to reverse the problem, a=F/m
Answer:

Explanation:
Energy consumed by 11 W energy efficient fluorescent bulb is given as

now we can say


now total cost of the energy used is given as


Now for conventional 40 W bulb we can say

now we can say


now total cost of the energy used is given as


So total money saving is given as
