just olya [345]
The answer is false. The speed of the astronaut cancels out the force of gravity, causing a 'stationary freefall'. While under these effects, it is not required for an astronaut to 'strengthen' his body.

The work function for magnesium is 3.70 ev. what is its cutoff frequency?
alexandr402 [8]

The cutoff frequency for magnesium is 8.93 x 10¹⁴ Hz.

<h3>What is cutoff frequency?</h3>

The work function is related to the frequency as

W0 = h x fo

where, fo = cutoff frequency and h is the Planck's constant

Given is the work function for magnesium is  3.70 eV.

fo = 3.7 x 1.6 x 10⁻¹⁹ / 6.626 x 10⁻³⁴

fo = 8.93 x 10¹⁴ Hz.

Thus, the cut off frequency is 8.93 x 10¹⁴ Hz.

Learn more about cutoff frequency.

Which is an example of electrical energy being converted or changed into light energy?
Lera25 [3.4K]
When I see the word "which" at the beginning of your question,
I just KNOW that there's a list of choices printed right there
next to he part that you copied, and for some mysterious
reason, you decided not to let us see the choices.

Any flashlight, light bulb, laser, or spark ... like lightning ...
converts some electrical energy into some light energy.

When you hold a small amount of sodium chloride in a flame, you observe that the flame is bright yellow. What can you do to be s
Anon25 [30]

To be sure that the color is due to sodium, do a flame test. This is used to identify the presence of small number of metal ions in a compound. For sodium, the brilliant color of bright yellow is a result of an excited electron in a very high level of energy and fall to a lower level called the ground state. 

In addition, metals have different jump sizes in the energy level and this means that each different metal will have a different pattern of spectral lines, which results to different flame color.
