Electrons are emitted from the surface of a metal in photoelectric effect.
<h3>What is the photoelectric effect?</h3>
The photoelectric effect is the emission of electron from the surface of a metal when light is shone on the surface..
For electrons to be emitted, the light must have a certain frequency known as threshhold frequency.
Therefore, electrons are emitted from the surface of a metal in photoelectric effect.

Answer:
I think that's gonna be 96g
Answer:
95.54mL
Explanation:
To calculate the volume that would have that mass, what is needed to be done is to use the formula that relates mass, density and volume.
Mathematically,
mass = density * Volume
But in this particular question we are to calculate the volume, we already have the mass and the density.
Rearranging the equation gives the following:
volume = mass/density
Our mass here is 75.0g while our density is 0.785g/mL
Hence, volume = 75/0.785 = 95.54mL
Answer:
According to Goog|e, "As the thumb is opposable, <u>it allows people to position it against other digits of the hand to manipulate or hold an object</u>. Some evidence suggests that this ability makes the thumb responsible for roughly 40% of the hand functions."

<span>The </span>abundance of a chemical element<span> is a measure of the </span>occurrence<span> of the </span>element<span> relative to all other elements in a given environment. Abundance is measured in one of three ways: by the </span>mass-fraction<span> (the same as weight fraction); by the </span>mole-fraction<span> (fraction of atoms by numerical count, or sometimes fraction of molecules in gases); or by the </span>volume-fraction<span>. Volume-fraction is a common abundance measure in mixed gases such as planetary atmospheres, and is similar in value to molecular mole-fraction for gas mixtures at relatively low densities and pressures, and </span>ideal gas<span> mixtures. Most abundance values in this article are given as mass-fractions.
