Answer: d. all of the above
Explanation:
A wildfire can be either naturally occurring or induced by humans for their own benefit. Is likely to exert a negative impact on the wildlife. A fire is likely to spread quickly to the entire canopy cover of the forest trees. This will destroy the availability of food and other resources. Many birds and animals will loose their habitat or shelter. The destruction of the floral species will cause migration of the faunal species to other locations. Therefore, the biodiversity of the region will be lossed.
Answer:
the free electron density of lithium is 2.3 × 10²⁸ /m³
Explanation:
The Fermi energy is 4.72 eV.
The Fermi energy (highest filled orbital energy ) of free electron is

Rearrange the above equation for free electron density of lithium

where,
h = 6.626 × 10⁻³⁴J.s
= 9.11 × 10⁻³¹kg
= 4.72eV

Thus, the free electron density of lithium is 2.3 × 10²⁸ /m³
I have no idea just getting points
Answer:
Because it unites particle and wave nature.
Explanation:
De Broglie wavelength can be defined as the,

Here, h is planks constant, m is the mass of electron, v is the velocity of electron.
Since the de Broglie wavelength can behave like the photon wavelength with respect to the momentum
It unites particles and waves nature ,so De Broglie wavelengths is probability waves associated with the wave function according to physicists.
A : A nebular cloud of dust and gas is the correct answer.
