Why is fossil fuel considered a nonrenewable energy source?​

Chemistry
1 answer:
IRINA_888 [86]3 years ago
3 0

Answer:

\boxed {\tt Takes \ many \ years \ to \ replenish}

Explanation:

A nonrenewable is a resource that cannot quickly be regenerated. A nonrenewable resource will eventually run out, and it cannot be remade for many years.

For example, <u>fossil fuel </u>is formed from fossils after millions of years of heat and pressure turn them into fuel. Since they take many years to create, they are a <em>nonrenewable energy source.</em>

For the function F(x) = 1, which of these could be a value of F(x) when x is<br> close to zero?
Sonbull [250]

Answer:

A.  -10,000

Explanation:

When x approaches zero, the graph tells us that F(x) either becomes extremely large or extremely small.  The best answer is therefore A:  -10,000.  Best, because we aren't given the exact value of x, but clearly the other results require that x be greater than 1 or less than -1, which is far from zero.

The light produced by the electron in strontium has a wavelength of 608 nm. How much energy must be added to strontium to get it
liq [111]

According to Einstein the energy of photon is given by the equation,

E = hν = h . c/λ

where h is Planck's constant, c is the speed of light, ν is the frequency of light and λ is the wavelength of light.  

Given, wavelength = 608 nm = 608 x 10⁻⁹ m  

Conversion factor: 1 nm = 10⁻⁹ m  

c = 3 x 10⁸ m/s

h = 6.626× 10⁻³⁴ J.s

Substituting the data into the equation we get,  

E = h . c/λ

E = 6.626× 10⁻³⁴ J.s x (3 x 10⁸ m/s) / 608 x 10⁻⁹ m  

E =  3.27 x 10⁻¹⁹J

3.27 x 10⁻¹⁹J  energy must be added to strontium to get it to produce 608 nm wavelength.
