How do you use a compass to find the flow through a wire?
A compass can be used to find the flow of current through a wire by placing the compass near the wire. The needle of the compass will align with the magnetic field created by the current flowing through the wire, indicating the direction of the current flow. The needle will point in the direction from which the current is coming.
Why do you think scientists cannot collect temperature and volume data for an enclosed gas at temperatures near absolute zero?
At temperatures near absolute zero, the gas particles possess very low kinetic energy and move sluggishly, making their behavior difficult to study. It's challenging to accurately measure temperature and volume changes in such conditions due to the extremely low energy levels involved. Additionally, standard measuring instruments may not function effectively at these temperatures.
Why does a compass needle move when placed near a wire carrying an electric current?
A compass needle moves near a wire carrying an electric current due to the magnetic field generated by the flow of electrons in the wire. This magnetic field interacts with the magnetic field of the compass needle, causing it to align itself with the direction of the current flow.
What happened unexpectedly when mercury was cooled to near absolute zero?
When mercury was cooled to near absolute zero, it displayed superconductivity at around 4.2 Kelvin. This means that it could conduct electricity without any resistance, a property not typically seen in metals at such high temperatures.
What do you call a person who studies matter at a very low temperature?
A person who studies matter at very low temperatures is called a cryogenicist. They work with materials and systems at extremely cold temperatures, often near absolute zero, to study their properties and behavior.
What is the study of properties of devices at temperatures near absolute zero called?
Physics of low temperatures.
When temperatures are near absolute zero what causes atoms to clump?
the answer is Who cares?
When temperatures near absolute zero what process causes Atoms to begin to clump?
Condensate is when temperatures are near absolute zero and the process causes atoms to begin to clump. When the temperatures gets colder and colder, the atoms aren't able to move.
Where do ocean current flow near to?
equator
What flow near the bottom of the ocean and sometimes flow on top of other currents?
Turbidity Current.
Does a compass turn near a closed circuit wire?
It will if there is current flow
How do you use a compass to find the flow through a wire?

The needle will point in the direction from which the current is coming.
When temperature are near absolute zero what process causes atoms to begin to clump?
Near absolute zero, atoms begin to clump together due to a phenomenon known as Bose-Einstein condensation, which is a state of matter where a large number of particles occupy the same quantum state. This clumping occurs because atoms lose their individual identities and behave as a single entity at such low temperatures.
What is the relationship between current and frequency in AC circuit?
Two words: skin effect. Now let's chat. Picture a wire with DC flowing through it. We are going to look at a cross section of the wire without interrupting current flow. Make sense? Picture it. When current flows in a wire in only one direction (DC), it uses all the available metal in the wire. Current flow in the middle of the wire will be about the same per unit of cross sectional area as current flow will be near the outside of the wire. Let's switch our DC for some AC. AC (alternating current) will flow in one direction for a while and then reverse direction to flow the other way for a while. Such is AC. And AC will cause current flow that uses all the available cross sectional area of the wire just as DC does, but only at low frequency. At higher and higher frequencies, current flow in the wire will shift away from the center and be more concentrated near the surface of the conductor. Near the skin of the conductor. AC of higher frequencies will promote current flow by skin effect, and that is the effect of frequency in AC current flow.

Can a magnet stop an electric current?
A magnet cannot stop an electric current, but it can influence the flow of the current. Moving a magnet near a wire carrying an electric current can induce a voltage in the wire, which can affect the behavior of the current.
Why does a compass needle move when placed near a wire carrying an electric current?
A compass needle moves near a wire carrying an electric current due to the magnetic field generated by the flow of electrons in the wire. This magnetic field interacts with the magnetic field of the compass needle, causing it to align itself with the direction of the current flow.
