I know of two reasons. I'm sure there are more.
#1). No chemical process can account for the distribution of energy
that we see coming from the sun. I mean the portions of the total
that are radio waves, heat waves, light waves, x-rays, and gamma rays.
#2). A pile of the most energetic known chemicals, with the mass
and volume of the sun, in the process of reactions and emitting
energy, would have been burned out, all over and done with, long ago.
I read somewhere many years ago that a pile of coal the size of
the sun could burn for 160 years. Even if it were ten million times
as long as that, it would still be way short of the 4.6 billion years
that the Earth has existed.
I believe the answer is “amplitude”.
Answer:
Explanation: there are three types of fossil fuels which can all be used for energy provision; coal, oil and natural gas. Coal is a solid fossil fuel formed over millions of years by decay of land vegetation. When layers are compacted and heated over time, deposits are turned into coal.
A surfer is riding a wave with an amplitude of 6 feet and a period of 24 feet. If the wave completes a period in 8 seconds.The speed of the surfer is 3ft/sec.
A wave's amplitude is defined as its largest displacement on either side of its mean location.
The quantity of oscillations a wave makes in a second is referred to as frequency of wave.
The amount of time it takes to complete one vibration, from A to B, is referred to as time period.
As we know,
ν = λf
where, ν = speed
λ = wavelength
f = frequency
also,
Putting in the values in equation ν = λf gives us,
ν = 24 × ( period of wave must means wavelength of 24ft)
ν = 3ft/sec.
