a) 1.9 × 10¹⁰
b) 1.9 × 10¹¹
c) 1.9 × 10¹²
d) 1.9 × 10¹³

Answer 1

Answer:

When expressed in CGS units of dyne/cm2, it will be equal to (1 N = 105 dyne, 1 m2 = 104 cm2) . Young's modulus of steel is 1.9 x 1011 N/m2.

Answer 2

Answer:

"Gases are less dense than solids and liquids because their molecules are far apart in comparison to solids and liquids. ... The greater the volumemass, the more dense the material is. Because the molecules of a gas are spread apart, they have the least volumemass, and are therefore less dense."
