Answer:
Rate at which current flows is measured in amperes
Explanation:
The rate of flow of electrons constitutes the current. The electrons flow from lower electric potential to higher electric potential. When there is no potential difference then no electron will flow. The direction of the current and the electron are in opposite direction.
The direction of electron from the negative terminal to the positive terminal. The direction of current is from the positive terminal to the negative terminal.The current is measured in ampere.
The expression for current and the charge is as;
Here, q is the charge, t is the time taken and I is the current.
According to the given problem, Jodi made a list about electric current to help her study for a test. He described that electrons move from areas of low to high electric potential, voltage causes current to flow and movement of electrons is continuous in a current.
But he did error. It should be "rate at which charges flow" instead of rate at which current flow.
Therefore, the option (4) is correct.
Answer:

Explanation:
To solve this equation we will have to consider that the bubble is filled with an Ideal Gas and as such we can use the Ideal Gas Law

Where
= Pressure
= Volume
= Moles
= Ideal Gas Constant
= Temperature
Now since we know that the value for the temperature and moles is constant we can simply use Boyles Law for the two states

Let us look at the two states
State 1 (at top)
Pressure = 
Volume = 
State 2 (at bottom)
Pressure = 
Where
= Density of liquid (1000 kg/m³)
= Acceleration due to gravity (9.8 m/s²)
= Height of liquid (0.200 m)
Pressure = 
Volume = 
Inputting these values into the Boyles Law

plasmas are a lot like gases
hope this helps.
m =dm ______ 10.000
Meters
The metre is a unit of length in the metric system, and is the base unit of length in the International System of Units (SI).
As the base unit of length in the SI and other m.k.s. systems (based around metres, kilograms and seconds) the metres is used to help derive other units of measurement such as the newton, for force.
Answer:
the first one is Primary
the second one I think it's Mature but I don't know
