The answer is homogenous i think
Answer:
λ = 0.002 nm
The given photon is either x-ray or gamma ray because the range of x-ray and gamma ray is 1 nm-0.1 pm.
Explanation:
Given data:
Energy of photon = 1.10 × 10⁻¹³ J.
Wavelength of photon = ?
Solution:
Formula:
E = h.c / λ
λ = h. c / E
λ = 6.626 × 10⁻³⁴ j. s × 3×10⁸ m/s / 1.10 × 10⁻¹³ J.
λ = 19.878 × 10⁻²⁶m / 1.10 × 10⁻¹³ J
λ = 18.071 × 10⁻¹³ m
λ = 18.071 × 10⁻¹³ × 10⁹
λ = 18.071 × 10⁻⁴ nm
λ = 0.002 nm
The given photon is either x-ray or gamma ray because the range of x-ray and gamma ray is 1 nm-0.1 pm.
Explanation:
Elements heavier than Helium are synthesized in a number of environments. For elements that are lighter than Iron, those elements are synthesized during various phases in the evolution of massive stars. For elements heavier than Iron, one needs quite a bit of energy input to form these heavy elements.
Answer:
d] 74.1 cm²
Explanation:
Product means that the values given must be <u>multiplied</u>.
13 cm × 5.7 cm = 74.1 cm²
1)Agricultural wastes will not be available if the basic crop is no longer grown. 2)Additional work is needed in areas such as harvesting methods. 3)Land used for energy crops maybe in demand for other purposes, such as faming, conservation, housing, resort or agricultural use. 4)Some Biomass conversion projects are from animal wastes and are relatively small and therefore are limited. 5)Research is needed to reduce the costs of production of Biomass based fuels. <span>6)Is in some cases is a major cause of pollution.</span>
