Answer:
The final pressure will be 0.67 atm.
Explanation:
Using Boyle's law
Given ,
V₁ = 10 L
V₂ = 15 L
P₁ = 1.0 atm
P₂ = ?
Using above equation as:
<u>The final pressure will be 0.67 atm.</u>
The correct answer is
<span> (3) 3.2 × 10^−19 C
In fact, electric charge is quantized: the elementary charge is the charge of the electron, </span>
, and every particle can only have an electric charge which is an integer multiple of this value. Of the options listed above, only option (3) is an integer multiple of the elementary charge: in fact, it corresponds to 2 times the electron charge:

Answer:
The current in the circuit is 0.15 Ampere
Explanation:
The given parameters of the cell are;
The electromotive force (e.m.f.) of the cell, E = 1.5 V
The resistance of the cell, r = 2.5 ohm
The resistance of the ammeter = 0.5 ohm
The resistance of the resistor = 7.0 ohm
The formula for the e.m.f., E of a cell is given as follows;
e.m.f. E = I·(R + r)
Where;
I = The current in the circuit
R = The sum of the resistances in the circuit = 7.0 Ω + 0.5 Ω + 2.5 Ω = 10 Ω
Therefore, we have;
Substituting the known values, gives;
The current in the circuit, I = 0.15 Ampere.
