What do we call the minimum energy that is required by an electron to leave the metal target in the photoelectric effect?Select one of the options below as your answer: A. energy function B. minimum function C. work function D. quanta E. electrical energy

Answers

Answer 1

Answer:

Answer:

C. work function

Explanation:

In the photoelectric effect, the energy of the incident photon is used in part to extract the electron from the metal (and this energy is called work function) and the rest is converted into kinetic energy of the electron. In formula:

$hf = \phi +K$

where

hf is the energy of the incident photon, which is the product between h (the Planck constant) and f (the photon's frequency)

$\phi$ is the work function

K is the kinetic energy of the photoelectron as it leaves the material

Answer 2

Answer: The work function is what we call the minimum energy that is required by an electron to leave the metal target in the photoelectric effect.

Which one is having lesser ressistance. a 60w bulb or a 40w bulb?

Answers

Power dissipation = (voltage across the component)² / (resistance of the component)

Since the resistance is in the denominator of the fraction in this formula for the
quantity of power dissipated, you can see that when the supply voltage is constant,
the smaller resistance dissipates more power.

So the 60w bulb has lower resistance than the 40w bulb.

HELP ME PLEASEE Why are chemical processes unable to produce the same amount of energy flowing out of the sun as nuclear fusion

i have no clue about it :(

Answers

One of the major differences between nuclear reactions and chemical reactions is that nuclear reactions involve larger amount of energy than chemical energy. This is because the force between the protons and neutrons in the nucleus of an atom is much higher than the force of attraction between electrons and the positively charged nucleus, hence nuclear reactions involves/requires a larger amount of energy (because it's reactions involve the nucleus) than chemical reactions (because it's reactions involve the electrons).
Thus, during nuclear fusion, two light nuclei are bombarded against one another to produce a larger/heavier nuclei with the release of large amount of energy (because the forces between the protons and neutrons are much higher) unlike when two atoms/molecules are chemically combined together to form a new molecule with the rearrangement of electrons in the valence shells of the participating molecules.

A box of groceries requires 5.0 newtons of force to lift it up 1.0 meter. How much work is done?

Answers

Work is defined as the amount of force done multiplied by the distance it was applied. Since it is already given that the object of interest (a box of groceries) was lifted up 1 meter by a force of 5 newtons, work done can be solved using the following formula:

Work = Force * distance
Work = 5 N * 1 meter
Work = 5 N*m = 5 J

The quantum mechanical model of the atom ____. a. defines the exact path of an electron around the nucleus b. was proposed by Niels Bohr c. involves finding an electron somewhere in a specific orbital d. has many analogies in the visible world

Answers

Answer:

Quantum mechanical model = involves finding an electron somewhere in a specific orbital.

Explanation:

The quantum mechanical model of an atom involves finding an electron somewhere in a specific orbital. This method is completely based on mathematical calculations. It defines the probability of finding an electron rather than its reality.

These are designated by some letters like s, p, d, f...... and the corresponding energy levels are 1st, 2nd, 3rd and so on.....

So, the correct option is (c) "involves finding an electron somewhere in a specific orbital".

c. involves finding an electron somewhere in a specific orbital
