Since the volume of both the lead and the sand is 1.0-cm3, the exactly 1.0-cm3 of water is displaced in both cases.
<h3>How does the volumes compare?</h3>
The commonest way to measure the volume of a substance is by the displacement method. In this method, the substance is added into water and the volume of the water displaced is measured.
Let us note that the volume of water displaced is equal to the volume of the object. Since the volume of both the lead and the sand is 1.0-cm3, the exactly 1.0-cm3 of water is displaced in both cases.

Answer:
The area is 2.5 m²
Explanation:
Step 1: Data given
A car has a 25 m² hydraulic lift platform that weighs 15000 N
The smaller piston required a force to lift = 1/100 its weight
Step 2: Calculate the area of the smaller piston
Pressure = Force / Area
F1 / A1 = F2 / A2
⇒ with F1 = weight of the hydraulic lift = 15000 N
⇒ with A1 = area of the hydraulic lift = 25 m²
⇒ with F2 = 1/100 of it's weight = 1500 N
A2 = F2 / (F1/A1)
A2 = 1500 ( 1500/25)
A2 = 2.5
The area is 2.5 m²
Benzene is the simplest example of the aromatic compound
Firstly, we want to explain what is the meaning of aromaticity?
the aromaticity is called on any compound which has cyclic shape and has a resonance. Resonance is delocalization of the electrons (which form the double bond) in the molecules, in other words, the double bond moves through the compound by the movement of electrons which leads to increasing the stability of the compound by this process which called resonance. The resonance may occur in open or cyclic compounds, and if it occurs in cyclic compounds, these compounds are called aromatic compounds. So, the benzene considered to be the simplest aromatic compound where it is not only has a resonance in a cyclic ring but also it was the first aromatic compound discovered and also, the most common aromatic compounds are derivatives of it (benzene).
