Voltage is often referred to as Electro-Motive Force, or EMF. It is what causes current to flow in a conductor. Also called volt.

What device did J. J. Thomson use to detect electrons and measure their properties?
J. J. Thomson used a cathode ray tube to detect electrons and measure their properties. By studying the behavior of electrons in the tube, he was able to determine their charge-to-mass ratio, leading to the discovery of the electron.
What measure of electrical energy transfers by electrons in a circuit?
The measure of electrical energy transferred by electrons in a circuit is typically measured in joules (J) or kilowatt-hours (kWh), which is often used for billing purposes by utility companies.
What unit is used to measure the electric force that causes the electrons to move?
This question is incorrect. Electricity is defined as the accumulation/ movement of electrons. The reason that electrons move is the same reason gravity exisits. They are just natural phenomena. There is no electric force that makes electrons move. It is the attractive/ repulsive forces between the protons and electrons. There is no such defined force you are asking about. The closest unit to answer this question is the Coloumb.
Why is the wavelength 275 nm used to measure absorbance of caffeine?
The wavelength of 275 nm is used to measure absorbance of caffeine because it corresponds to the maximum absorbance peak for caffeine. By using a wavelength where caffeine absorbs strongly, we can accurately measure its concentration in a sample based on the amount of light absorbed at 275 nm.
What is it called if electrons encounter difficulty as they move through a circuit?
Resistance, or electrical resistance. The SI unit is the ohm.
Which term indicates how strongly an atom attracts the electron in a chemical bond?
Linus Pauling defined electronegativity as "the ability of an atom in a molecule to attract electrons to itself."

How do you determine the velocity of an electron?
X-rays are reflected by electrons. The shift in frequency/wavelength of the reflected X-ray compared to the original X-ray (Doppler effect) can be used to measure the speed of the electrons.
What is one in which one element pulls on the shared electrons more than the other element?
Electronegativity is the term used to describe the ability of an element to attract shared electrons in a chemical bond. When one element has a higher electronegativity than another in a covalent bond, it will pull on the shared electrons more strongly, creating a polar covalent bond.
What tools are used to measure qualitative data?
The answer depends on the type of qualitative data.You would use your taste buds as tools to distinguish between sweet, sour, salt and so on.You could use you sight to determine the colour of eyes, hair or cars.You would use your own judgement to choose between "strongly agree", "agree", "disagree" or "strongly disagree".
An atoms relative ability to attract electrons shared in a chemical bond is known as its?
electronegativity. It describes how strongly an atom attracts electrons in a chemical bond, denoting its tendency to gain electrons and form negative ions. Electronegativity values are used to predict the type of bond (ionic, polar covalent, or nonpolar covalent) that will form between atoms.
Which electrons are used in chemical bonding?
Valence electrons are the electrons that are used in chemical bonding. These are the electrons in the outermost energy level of an atom.
What is a pad lockable push button?
It is a push button that has the capacity to be locked so as to render is inoperable when pushed. These types of button locks are used on start buttons as a safety measure in industrial applications.
What are electrons are used in bonds?
valence electrons
What is the term used for a person who is strongly committed to a party or a group?
The term used for a person who is strongly committed to a party or a group is usually referred to as a "loyalist" or a "partisan."
