<h2>Answer:</h2>

<u>The statement is </u><u>False</u>

<h2>Explanation:</h2>

Contaminated rags may contain plastic and other materials that cannot be defused in soil and they remain there for a long period of time. Another reason to avoid disposal of contaminated material in earth is that it may also contain toxic materials which may result into land pollution. So it is not recommended to dispose contaminated rags in landfills.

What is the input of energy for a device that provides 50 units of useful energy and has an efficiency of 0.55?
ki77a [65]

If that's the case, then  

                          50 units = 0.55 x the input energy

Divide each side by  0.55 :        

                   50 units/0.55  =  the input energy = 

                              <span> 90 and 10/11 units</span>

Violet light of wavelength 400 nm ejects electrons with a maximum kinetic energy of 0.860 eV from sodium metal. What is the bind
Travka [436]

Answer:

Binding Energy = 2.24 eV

Explanation:

First, we need to find the energy of the photon of light:

E = hc/λ

where,

E = Energy of Photon = ?

h = Plank's Constant = 6.626 x 10⁻³⁴ J.s

c = speed of light = 3 x 10⁸ m/s

λ = wavelength of light = 400 nm = 4 x 10⁻⁷ m

Therefore,

E = (6.626 x 10⁻³⁴ J.s)(3 x 10⁸ m/s)/(4 x 10⁻⁷ m)

E = (4.97 x 10⁻¹⁹ J)(1 eV/1.6 x 10⁻¹⁹ J)

E = 3.1 eV

Now, from Einstein's Photoelectric Equation:

E = Binding Energy + Kinetic Energy

Binding Energy = E - Kinetic Energy

Binding Energy = 3.1 eV - 0.86 eV

<u>Binding Energy = 2.24 eV</u>
