100 watts = 100 joules per second
22 watts = 22 joules per second
Saving = 78 joules per second
1 hour = 3,600 seconds
24 hours = 86,400 seconds
(78 joules/sec) x (86,400 sec) = 6,739,200 joules
Answer:
Therefore the required solution is

Explanation:
Given vibrating system is

Consider U(t) = A cosωt + B sinωt
Differentiating with respect to t
U'(t)= - A ω sinωt +B ω cos ωt
Again differentiating with respect to t
U''(t) = - A ω² cosωt -B ω² sin ωt
Putting this in given equation


Equating the coefficient of sinωt and cos ωt
.........(1)
and

........(2)
Solving equation (1) and (2) by cross multiplication method


and 
Therefore the required solution is

C. FM radio waves is the answer.
1. All of the above
2. Lack of consistent sunlight
3. Nonpolluting & Can be developed anywhere
4. Protons and Neutrons
sorry the answer is so late...Hope it still helps u
:)
Also I'm pretty sure all the answers I provided are correct but I'm not sure 4 a fact so plz let me know...
<span>The jump from 1966 to 16347 is the largest one or simply we can say it is hard to lose the 3rd electron.Whereas, it is relatively easy to lose the first two electrons.
So there will be only 2 electrons in the outer most shell.
According to the information mentioned above we can conclude the </span><span>unknown element likely belongs to the second group.
