Need science : question 1: which subatomic particle has a negative charge? all of them neutron electron proton question 2: if an atom has 2 protons, 3 neutrons, and 3 electrons, what is the electrical charge of the atom? positive negative neutral varies question 3: a neutral atom that gains electrons will have what kind of charge? positive negative neutral varies question 4: which of the following describes the principle of the conservation of charge? a charge is created a charge cannot be transferred charge cannot be created or destroyed, just transferred charge can be destroyed question 5: what law states that when there is an interaction between charged objects there is a non-contact force which acts over some distance of seperation? faraday's law ohm's law coulomb's law interaction law question 6: which of the following describes an insulator? does not allow electrons to move through it allows electrons to move through it is always a solid is always a gas question 7: what are most conductors made of? wood paper plastic metal question 8: which of the following describes why lightening rods are put on top of houses? insulate the house conduct the lightening away from the house reduce amount of static discharge reduce the loudness of thunder question 9: your computer is powered by which of the following? electrical current moving protons overflow of electrons static electricity question 10: wire is used to attach a battery to a penny and is then used to light a small light bulb. the light bulb is lit due to which of the following? static electricity electric current electron overflow moving protons

Question 1:

which subatomic particle has a negative charge?

Electron

Explanation:

There are three subatomic particles

electron, neutron and proton

out of all electron is negatively charged, proton is positively charged while neutron is a neutral particle

Question 2:

if an atom has 2 protons, 3 neutrons, and 3 electrons, what is the electrical charge of the atom?

Negative

Explanation:

As we know that

so it is negatively charged

Question 3:

A neutral atom that gains electrons will have what kind of charge?

Negative

Explanation:

Since electron is a negatively charged particle so on gaining an electron it will get negative charge

Question 4:

which of the following describes the principle of the conservation of charge?

Charge cannot be created or destroyed, just transferred

Explanation:

charge can transfer from one atom to other atom but we can not create a charge  or we can not destroy a charge

Question 5:

what law states that when there is an interaction between charged objects there is a non-contact force which acts over some distance of seperation?

Coulomb's law

Explanation:

Coulombs law gives the force of attraction or repulsion between two charges which is given as

Question 6:

which of the following describes an insulator?

Does not allow electrons to move through it

Explanation:

in insulators all the charges are bounded and not free to move

Question 7:

what are most conductors made of?

Metal

Explanation:

All conductors are source of free electrons in which they can move freely

Question 8:

which of the following describes why lightening rods are put on top of houses?

conduct the lightening away from the house

Explanation:

lightening rod gives the path to excess charge to flow towards ground

Question 9:

your computer is powered by which of the following?

Electrical current

Explanation:

All electrical device is powered by current source

Question 10:

wire is used to attach a battery to a penny and is then used to light a small light bulb. the light bulb is lit due to which of the following?

electric current

Explanation:

electric current gives energy to glow the bulb
