Answer:

B. The voltage is the same across all resistors in the circuit.

Explanation:

The answer choices are:

A.The current is the same across all resistors in the circuit.

B.The voltage is the same across all resistors in the circuit.

C. As more resistors are added, the current will decrease.

D. The sum of the voltage drops will equal the total voltage.

<h2>Solution</h2>

In a simple parallel circuit, each component (resistor) is connected directly to the battery forming different branches or pathways to the current.

Thus, the ends of each resistor receives the total potential difference or voltage from the battery, which is what the statement B. asserts. Hence, statement B is true.

On the other hand, the current will split among the different pathways, following Ohm's law: the greater the resistance of the resistor the lower the current. Thus, the statement A is false.

For a parallel circuit, the total resistance decreases as more resistors are added, which means that, again following Ohm's law, the current will increase, contradicting the statement C. Thus, the statement C is false.

It is in the series circuit that 'the sum of the voltage drops will equal the total voltage"; in a parallel circuit the voltage drop is the just one and the same for each resistor. Thus, the statement D is false,too.

According to avagados law the volume of gas will

notka56 [123]

Answer: This law is sometimes referred to as the 'Avogadro's Hypothesis' or 'Avogadro's Principle'. This is an experimnetal gas law that is relating to the volume of gas to the amount of substance of gas that is present to the state. This law also states that ''Equal volumes of all gases, at the same temp. and pressure, have the equal amount of molecules.''.

I hope this helps you and good luck! ☺

antoniya [11.8K]

This is an example of diffusion. The nitrous oxide is moving from an area of higher concentration, down the gradient into the cell, which has a lower concentration. Since the cell doesn't have as much N2O as the surrounding environment, the gas will move inside the cell as a way of attaining equilibrium.

Answer:

200 grams is the mass of 15% of the solution of lime that is formed by dissolving 30g of calcium hydroxide in water.

Explanation:

Mass of solution = M

Mass percentage of the solution of lime = 15%

Mass of lime or calcium hydroxide = m = 30 g

The Formula of mass percentage is given as :

$m/m\%=\frac{m}{M}\times 100$
