Answer:
Fats and waxes are solid at room temperature because they are made of saturated fatty acids. In contrast, oils are mostly unsaturated fatty acids. ... In contrast, unsaturated fatty acids have several kinks in their structure and therefore, are liquid at room temperature.

Answer:
25 measurements need to be taken
Explanation:
Given:
individual uncertainty,
- Let the uncertainty mean be
<u>Now we have the relation as:</u>
where:
n= number of measurements
measurements need to taken in this case.
Answer:
Explanation:
q₁ = 8 x 10⁻⁶ C , q₂ = 3.5 x 10⁻⁶ C , q₃ = -2.5 x 10⁻⁶ C
Force between charge = 9 x 10⁹ x q₁ q₂ / d²
Force on q₁ due to q₂
= 9 x 10⁹ x 8 x 10⁻⁶ x 3.5 x 10⁻⁶ /( .10 )²
= 25.2 N . This force will be negative as it will point towards left ( q₂ will repel q₁ )
Force on q₁ due to q₃
= 9 x 10⁹ x 8 x 10⁻⁶ x 2.5 x 10⁻⁶ /( .15 )²
= 8 N . This force will be negative as it will point towards left ( q₃ will attract q₁ )
Net force = 25.2 N - 8 N
= 17.2 N .
