When energy from incident photons is transferred to the electrons, an electron in a metal get enough energy to escape from its atom as hypothesized in the photoelectric  effect.

Answer: Option D

<u>Explanation:</u>

At the point, when the light incident on a metal, electrons can be shot out from the outside of the metal in a wonder known as the photoelectric effect. This procedure is additionally frequently alluded to as photo emission, and the electrons that are shot out from the metal are called photo electrons. Regarding their conduct and their properties, photo electrons are the same as different electrons.

The prefix, photograph, basically discloses to us that the electrons have been shot out from a metal surface by incident light. In the light's wave model, Scientists predicted that expanding light amplitude increases the kinetic energy of radiated photo electrons while the increase in the intensity would increase in the estimated current.

kirza4 [7]

Answer:

m = 0.041 kg

Explanation:

As we know that the small particle is in equilibrium at an angle of 16 degree with the vertical

so here we can use force balance in vertical and horizontal direction

T cos\theta = mg

T sin\theta = qE

now from above equation we have

T = \sqrt{(mg)^2 + (qE)^2}

also by division of above two equations we have

\frac{qE}{mg} = tan\theta

qE = mg tan\theta

now from above equation again

T = \sqrt{(mg)^2 + (mg)^2 tan^2\theta}

T = mg sec\theta

0.420 = m(9.81) sec 16

m = 0.041 kg
