Answer:
V = 0.3724 m³
T = 27.836 N
Explanation:
Given :
m = 3.21 kg , W= 3.21 * 9.81 m / s² = 31.4901 N
ρ = 8.62 g / cm ³ = 8620 kg / m³
V = m / ρ = 3.21 kg / 8620 kg / m³
V = 0.3724 m³
when submerged the weight of brass cylinder is equal to the tension in string:
F = (0.3724m³) * (1000 kg / m³) * (9.81 m/s²²) = 3.653 ≈ 3.65 N
T = 31.4901 N - 3.65 N
T = 27.836 N
Pumice is used for cleaning foot. Foot are wet with warm water and then scrub by pumice so that hard and dry skin can be removed. It is quite effective in cleaning skin.
Pumice is also used as light weight material in concrete mix. Due to it porous texture, it is a good light weight material.
<h2>
Answer: Prism</h2>
In the eighteenth century Isaac Newton found out that <u>when a beam of light from the Sun, passes trhough a prism is decomposed in many different colors</u>. He named this phenomenom as dispersion of light.
This phenomenom occurs when a beam of white light (which is compound of many wavelengths or "colors") is refracted (the different rays of light are diverted depending on their wavelengths) in some medium, leaving their constituent colors separated.
Therefore:
<h2>Isaac Newton used a <u>prism</u> to break white light into its component colors.</h2>
Yes they are the power goes from one to another and if one goes off another will go off too
