Answer:
The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume.
Most atoms have three different subatomic particles inside them: protons, neutrons, and electrons. The protons and neutrons are packed together into the center of the atom(which is called the nucleus) and the electrons, which are very much smaller, whizz around the outside. Most of an atom is empty space.
I hope this helps you! :D
Answer:
The wavelength decreases
Explanation:
As you go along the EM spectrum from radio waves to gamma rays, the wavelength decreases as the wave's energy and frequency increase.
6:12:6: - this simplifies to 1:2:1 (answer)
You get the simplest form by dividing each of the 3 numbers by 6.
Joseph's percentage error would be 1.89%
<u>Explanation:</u>
Exact value of the density of aluminium = 2.699 g/cm³
Calculated value of the density of aluminium = 2.75 g/cm³
Percentage error = ?
We know:
Therefore, Joseph's percentage error would be 1.89%
