Answer:

The structure of Germanium crystals will be destroyed at higher temperature. However, Silicon crystals are not easily damaged by excess heat. Peak Inverse Voltage ratings of Silicon diodes are greater than Germanium diodes. Si is less expensive due to the greater abundance of element.

andrew11 [14]

Answer: Energy of a mole of these photons is $0.368\times 10^6Joules$

Explanation:

The relationship between wavelength and energy of the wave for 1 mole follows the equation:

$E=\frac{Nhc}{\lambda}$

E= energy

N= avogadros number = $6.023\times 10^{23}$

$\lambda$ = wavelength of the wave = $325\times 10^{-9}m$ $1nm=10^{-9}m$

h = Planck's constant = $6.626\times 10^{-34}Js$

c = speed of light = $3\times 10^8m/s$

$E=\frac{6.023\times 10^{23}\times 6.626\times 10^{-34}\times 3\times 10^8m/s}{325\times 10^{-9}m}$

$E=0.368\times 10^6Joules$

Thus the energy of a mole of these photons is $0.368\times 10^6Joules$

Two campers dock a canoe. One camper has a mass of 100.0 kg and moves forward at 3.0 m/s as he leaves the canoe to step onto the

Solnce55 [7]

Answer:

The combined speed of camper and canoe is 1.71 m/s.

Explanation:

Given that,

Mass of camper 1, m = 100 kg

Speed of camper 1, v = 3 m/s

The combined mass of another camper and canoe is, M = 175 kg

We need to find the combined speed of camper and canoe. According to the conservation of linear momentum, the momentum of first camper is equal to linear momentum of the canoe and the second camper.

$mv=MV\\\\V=\dfrac{mv}{M}\\\\V=\dfrac{100\times 3}{175}\\\\V=1.71\ m/s$

So, the combined speed of camper and canoe is 1.71 m/s.

Answer:

Iris

Explanation:

The iris seems to be the illuminated portion of the eyes which really covers the pupil. It controls the amount of light reaching the eye. The lens is indeed a translucent layer of the retina that serves to concentrate light and objects on the lens.
