Answer:
The current doubles
Explanation:
In a circuit, Ohm's law gives the relationship between voltage, current and resistance:
where
V is the voltage
R is the resistance
I is the current
In this problem,
V is held constant
R is halved:
Therefore, the new current is
So, the current doubles.
Answer:
Distinct means separate.
Option: C
<u>Explanation:
</u>
From the given sentence Argon has several properties that are separate from other gases. This sentence refers that Argon gas has many properties that are different from other gases.
The things are distinct from one another, they are different. Although, the solubility of oxygen is same as Argon. Argon is soluble in water in the form of nitrogen. <em>This gas is isolated through the liquid air fractionation only 0.94% argon is present in the atmosphere.
</em>
Answer:
Boyle's Law
Explanation:
Given that:
<u><em>initially:</em></u>
pressure of gas,
volume of gas,
<em><u>finally:</u></em>
pressure of gas,
volume of gas,
<u>To solve for final volume</u>
<em>According to Avogadro’s law the volume of an ideal gas is directly proportional to the no. of moles of the gas under a constant temperature and pressure.</em>
<em>According to the Charles' law, at constant pressure the volume of a given mass of an ideal gas is directly proportional to its temperature.</em>
But here we have a change in the pressure of the Gas so we cannot apply Avogadro’s law and Charles' law.
Here nothing is said about the temperature, so we consider the Boyle's Law which states that <em>at constant temperature the volume of a given mass of an ideal gas is inversely proportional to its pressure.</em>
Mathematically:
Answer:
c. As the thread is stretched, the coating thins and its resistance increases; as the thread is relaxed, the coating returns nearly to its original state.
Explanation:
This is in line with the result as shown in the data.
Stretching causes the coating to thin which in turn increases the resistance of the thread (conduction drops) releasing it backs returns the thread to nearly its initial values, but due to the strain already in the thread it does not return to its original values.
