Which equation represents ohm's law?
Literally, ohm's law implies that current (I) is directly proportional to voltage (V) and inversely proportional to resistance (R).
Mathematically, this can be represented as:
Convert the expression to an equation
Multiply both sides by R to make V the subject

Let's assume that the pressure given is 771 torr.
Answer:
747.44 torr
Explanation:
The eudiometer tube is a setup that collects gas in a liquid (generally water). After the thermal equilibrium, the gas becomes in equilibrium with the vapor of water above the liquid.
By Dalton's law, the total pressure of a mixture is the sum of the partial pressure of its components. The partial pressure is the pressure that the gas would have at the same conditions if it was alone. So, the pressure of the dry gas is its partial pressure.
The total pressure is the barometric pressure, and the partial pressure of the water vapor at 20°C is 23.56 torr (the value can be found at a thermodynamic table). So, the pressure of the dry gas (P) is:
771 = 23.56 + P
P = 771 - 23.56
P = 747.44 torr
I think the correct answer from the choices listed above is option B. If two wires run parallel and the current passes through both wires in the same direction, <span> the wires move apart because the magnetic fields of each wire are opposite, so they repel each other.</span>
Answer:
The spheres interact with one another, and a change in one might result in a change in another. Humans (biosphere) plough the fields with agricultural machinery made of geosphere materials, while the atmosphere (hydrosphere) provides precipitation to water the plants. The biosphere is home to all living organisms on the earth.
