A uniform cube is subjected to volume expansion. Each side gets decreased by 1%, then the bulk strain is 0.03.
<h3>What is Volume?</h3>
Volume is the space occupied by a three-dimensional object.
<h3 />
Given that, the side cube is l, then
volume V = l³

For change in volume
% Change in volume = 3× % change in length
= 3 × 1%
Hence, bulk strain = 0.03.
Thus, the bulk strain is 0.03.

Hello!
The set of compounds that have the same empirical formula is b) N₂O₄ and NO₂.
The Empirical Formula is the most simple representation of the atom ratio in a chemical compound. Of the listed sets of compounds, the only in which the atom ratio is the same for both compounds is the pair N₂O₄ and NO₂ in which the atom ratio N:O is 1:2. The Empirical Formula for this pair is NO₂.
N₂O₄ has the same atom ratio as NO₂ but this formula has each atom multiplied by two. However, its Empirical Formula is the same.
Have a nice day!
Answer:
False.
Explanation:
Friction is a resisting force that acts on a body to prevent its motion. Friction force acts opposite to the direction of motion.
