Answer:

The acceleration is 0.062 m/s^2.

Explanation:

mass = 12 kg

F = 30 N at 20° right

F' = 45 N at 50° left

Let the acceleration is a.

The net force is

F'' = F' cos 50° - F cos 20°

F'' = 45 x 0.643 - 30 x 0.94 = 28.94 - 28.2 = 0.74 N

According to the Newton's second law

0.74 = 12 x a

a = 0.062 m/s^2

Electromagnetic radiation of 5.16Ă—1016 Hz frequency is applied on a metal surface and caused electron emission. Determine the w

IgorC [24]

Answer:

Work function of the metal, $W_o=3.38\times 10^{-17}\ J$

Explanation:

We are given that

Frequency of the electromagnetic radiation, $f=5.16\times 10^{16}$ Hz

The maximum kinetic energy of the emitted electron, $K=4.04\times 10^{-19}\ J$

We need to find the work function of the metal.

We know that the maximum kinetic energy of ejected electron

$K=h\nu-w_o$

Where h=Plank's constant= $6.63\times 10^{-34} J.s$

$\nu$ =Frequency of light source

$w_o$ =Work function

Substitute the values in the given formula

Then, the work function of the metal is given by :

$W_o=h\nu -K$

$W_o=6.63\times 10^{-34}\times 5.16\times 10^{16}-4.04\times 10^{-19}$

$W_o=3.38\times 10^{-17}\ J$

So, the work function of the metal is $3.38\times 10^{-17}\ J$ . Hence, this is the required solution.

Place the types of radiation in order of INCREASING mass.

lubasha [3.4K]

Answer & explanation:

Gamma Radiation (γ): Also called gamma rays. Gamma radiation is made of electromagnetic waves, has zero charge and mass, continuously emits heat and has the ability to ionize air and make it conductive of electric current.

Beta radiation (β): Beta rays or beta particles, are electrons, negative particles with charge - 1 and mass number 0.
Alpha radiation (α): Also called alpha particles or alpha rays, are particles charged by two protons and two neutrons. They have positive charge +2 and mass number 4.
