Answer:

The correct answers are: negative; 4.8 X 10⁻¹⁵ C

Explanation:

An atom is the smallest particle of a material that retains the properties of that material. Then all materials are made of atoms. Each atom is formed by a nucleus with positive charge around which negative electrons move. At rest, the positive charge of the nucleus is equal to the sum of the negative charges of all the electrons that revolve around it. This means that the charge is neutral.

Static electricity, also called static energy; is the accumulation of an excess of electric charge, both positive and negative charge, in a material.

It is generated when two or more bodies come into contact. So, when static electricity is produced, as electrons have a negative charge, an object will have a positive charge (because it lost electrons) and one will have a negative charge (because it gained electrons).

With the latter in mind, as you walk on the carpet, electrons move from the carpet to their feet, leaving a negative static charge on you.

On the other side, the electrical charge that a body has is measured in coulombs (C). A coulomb is the amount of electric charge that circulates for 1 second through a section of a conductor, whose current intensity is 1 amp. A coulomb equals the charge of 6.25 x 10¹⁸ electrons.

You can apply rule of three as follows: if 6.25 x 10¹⁸ electrons are 1 coulomb, 3*10⁴ electrons how many coulombs are they?

charge=\frac{3*10^{4} electrons*1coulomb}{6.25*10^{18}electrons }

charge=4.8*10⁻¹⁵ C

So, the correct answers are: negative; 4.8 X 10⁻¹⁵ C

What are limitations of the calculated and indirect volume measurement?
tresset_1 [31]

Answer: The calculated volume measures the side of the cube to get the volume. An indirect measurement of volume measures the displacement of a liquid by a solid.

Explanation:

Volume is the amount of  the space occupied by an object. Volume can be used to measure the amount of the space occupied by the solid, liquid and gas.

When the direct measurement is not possible then the indirect measurement is used by taking the small part that object to calculate the whole part of that.  

The limitations of the calculated and indirect volume measurement are as follows,

The calculated volume measures the side of the cube to get the volume. An indirect measurement of volume measure the displacement of a liquid by a solid. For example, the volume of the liquid is displaced by the sponge is not equal to the volume of the sponge.
