The factor that most affects the flow of ocean currents is B. differences in temperature.
Correct answer is first option: <span>The direction of the charge flow is the same as the question
Explanation:
When we have battery (or any other source of electricity) we have flow of a charge. Charge flows from positive part of battery over a conductor (most often it is a wire) towards negative part of battery. This is what always happens.
Now lets observe what we have done in this question. We had wires connected to a battery and we had a flow of charge from positive to negative pole. Then we disconnect wires and </span><span>reconnect them at the opposite ends of the battery. The question is does the direction of flow of charge change? Answer is NO. Charge still flows from positive towards negative pole. The direction of flow of charge does not depend on how the wires are connected.
Imagine this:
there is line of people stretching from one end of room to opposite end. You need to take something from front part to back part of room. Imagine people pass that object one to another. Does the direction in which this object moves depend on how this line of people is arranged? Same is for wire and charge.</span>
Yes they do observe the law of conservation of mass
Answer:
No
Explanation:
The equation of state for ideal gases tells that:
where
p is the gas pressure
V is the gas volume
n is the number of moles of the gas
R is the gas constant
T is the absolute temperature
In this problem, we have a fixed mass of gas. This means that the number of moles of the gas, 
, does not change; also, the volume V remains the same, and R is a constant, this means that
So, as the pressure increases, the temperature increases.
However, here we want to understand what happens to the average distance between the molecules.
We have said previously that the number of moles n does not change: and therefore, the total number of molecules in has does not change either.
If we consider one dimension only, we can say that the average distance between the molecules is
where L is the length of the container and N the number of molecules. Since the volume of the container here does not change, L does not change, and since N is constant, this means that the average distance between the molecules remains the same.
