Calculate the pressure exerted by an book of mass 20kg occupying an area of 2 m square.​
kotykmax [81]

The answer is 100 Pa.

The formula for calculating pressure is :

<u>Pressure = Force ÷ Area</u>

<u />

We are given that :

  • mass = 20 kg
  • area = 2 m²

We also know that :

<u>Force = mass ×g</u>

<u />

So, force will be :

  • F = 20 × 10
  • F = 200 N

Now, we can finally calculate pressure :

  • P = 200 ÷ 2
  • P = 100 Pa

Classify each of the following bonds as non polar covalent polar or ionic
Soloha48 [4]
A) Polar (Cl is more electronegative than Si)
b) Nonpolar (Both atoms have the same electronegativity)
c) Ionic (Ionic bonds happen between a metal and a nonmetal)
d) Nonpolar (Hydrogen and carbon have about the same electronegativity) this is a common nonpolar bond)
You can identify the type of bon by looking at what is being bonded (nonmetal or metal) and the placement of the elements on the periodic table (electronegativity increases going up a group and going from left-right across a period).
