When you are talking about calculating the kinetic energy of an object, the formula is as stated:

Ek =1/2mv²

Where m is mass and v is velocity. Sub all those numbers in and you'll get 25J of kinetic energy.

What are the coefficients in this expression?
skad [1K]

6 and \frac{1}{3}

Explanation:

The expression:

     6a - \frac{3}{4}  + 7.5 - \frac{b}{3}

 A coefficient is a numerical constant usually placed before a variable in an expression.

They are used to multiply variables.

 Given equation is;

   6a - \frac{3}{4}  + 7.5 - \frac{b}{3}

There are two variables in this expression which are;

  a and  - b

  6 (a) - \frac{3}{4}  + 7.5 - b (\frac{1}{3} )

The coefficients in this expression are:

    6 and \frac{1}{3}

Photoelectrons are observed when a metal is illuminated by light with a wavelength less than 383 nm. What is the metal's work fu
Ulleksa [173]

Answer:

Work function of the metal is 3.24 eV.                                    

Explanation:

It is given that,

Wavelength, \lambda=383\times 10^{-9}\ m

Let W is the work function of the metal. It is given by using Einstein's photoelectric effect equation. It is given by :

W=\dfrac{hc}{\lambda}

W=\dfrac{6.63\times 10^{-34}\times 3\times 10^8}{383\times 10^{-9}}

W=5.193\times 10^{-19}\ J

Since, 1\ eV=1.6\times 10^{-19}\ J

So, W = 3.24 eV

So, the work function of the metal is 3.24 eV. Hence, this is the required solution.
