What is the frequency of radiation whose wavelength is 11.5 a0 ?
irakobra [83]

Answer:

The frequency of radiation is 2.61 \times 10^{17} s^{-1}

Explanation:

Given:

Wavelength \lambda = 11.5 \times 10^{-10} m

Speed of light c = 3 \times 10^{8} \frac{m}{s}

For finding the frequency of radiation,

  c = f \lambda

  f = \frac{c}{\lambda}

  f = \frac{3 \times 10^{8} }{11.5 \times 10^{-10} }

  f = 2.61 \times 10^{17} s^{-1}

Therefore, the frequency of radiation is 2.61 \times 10^{17} s^{-1}

The amount of work done by a heat engine equals the amount of thermal energy _____. added to the engine plus the waste heat adde
RideAnS [48]

added to the engine minus the waste heat

Explanation:

The amount of work done by a heat engine equals the amount of thermal energy added to the engine minus the waste heat.

Thermodynamics is used to measure the energy changes that accompanies physical and chemical process.

 In a system;

  Internal energy = Quantity of heat added - Work done on it

 internal energy is designated as ΔU

  quantity of heat as Q

   work done as W

                ΔU = Q - W

  so       W = Q  -   ΔU

some of the heat added added to the system goes as waste heat as no system is 100% efficient.

   the work done on a system goes in as thermal energy, internal energy and waste heat

If the earth had no atmospheres at all what would the sky look like
Stells [14]

Explanation:

After the shock of seeing animals falling from the sky and silence, comes what you may have already imagined; that is, we would die from lack of oxygen - and in about 3 minutes. The worst thing is that not even patients connected to respirators in hospitals or divers equipped with cylinders could survive, since there is a need for pressure to be able to breathe.
