<u>Answer:</u>
Option(a)
The density of 4.5 mL of a liquid that has a mass of 1.3 grams is 0.289g/ml
<u>Explanation:</u>
We know that density is given by mass upon volume i.e,
we are given volume of the liquid = 4.5mL
and mass of the liquid = 1.3 grams
So, by substituting the given values in the formula we obtain the density of liquid as
= 0.28888..
= approx 0.289 g/mL which is the density of the liquid
Answer:
Explanation:
According to question,
Charge 1 and charge 2 are
The distance between charges is 2 m
We need to find the force with which two positive charges repel. It is called electrostatic force of repulsion. It can be given by :
So, the electric force of repulsion is .
Each capacitor carry the same charge 'q'.
Discussion:
The voltage from the battery is distributed equally across all of the capacitors when they are linked in series. The three identical capacitors' combined voltage is computed as follows:
= V₁ +V₂ +V₃
This voltage may also be calculated using capacitance and charge;
V = Q/ C
= V₁ +V₂ +V₃
Provided that the total charge is 'q', hence the total voltage can be expressed as:
= (Q/C₁) + (Q/C₂) + (Q/C₃) = Q(1/C₁ +1/C₂ +1/C₃)
Therefore from the above explanation, it is concluded that each and every capacitor carry same charge 'q'.
