Electron revolves around the nucleus. Protons, neutrons are called nucleons because they form nucleus of the atom. Quarks are the fundamental particles which combines to form neutrons, protons and other particles.
Hence electron is the answer.

Which of the following statements are true? Check all that apply.

lidiya [134]

We have 6 levels and we will verify which of them is true.

A ) Electric charge is conserved

According to the conservation of charge, an electric charge can neither be created nor be destroyed.

Therefore this statement is TRUE.

B ) A positive charge and negative charge attract each other

According to the properties of charges, the opposite charges attract each other and similar charges repel each other

Therefore this statement is TRUE

C) Two positive charges attract each other.

Using the previous law, we can observe that this statement is false, because equal charges repel each other.

Therefore this statement is FALSE.

D ) Two negative charges repel each other.

Using the same principle as the two previous statements, two equal charges repel each other.

Therefore this statement is TRUE

E) Electric charge is quantized.

According to the quantization of charge, charges can take values only in integral multiples of a fundamental unit of charge.

Therefore this statement is TRUE.

F) A neutral object contains no charge.

A neutral object contains equal amount of negative and positive charge. Thus, in totality a neutral object contains no charge.

Therefore this statement is TRUE.

A boat has a mass of 6800 kg. its engines generate a drive force of 4100 n, due west, while the wind exerts a force of 830 n, du

erastova [34]

Let positive be west and negative be east because they are contrasting in directions.

The forces are 4100, -830, and -1200

The sum of the forces is 4100 – 830 – 1200 = 2070 N.

Newton’s law F = ma is used.
2070 = 6800 a

Isolating a will give us 2070 / 6800 = a

a = 0.34 m/s^2

A two-dimensional crystal has a rectangular unit cell, with spacings between the centers of the atoms of 0.5 nm in one direction

pav-90 [236]

So directly the cell density value in a rectangle is:

$5*10^{17} cells/cm^{2}$

In this exercise, we must first calculate the area of the rectangle, remembering that you need to convert from nm to cm is:

$A=B*H\\A=(0.4*10^{-7})*(0.5*10^{-7})= 2*10^{-15}$

Next, let's calculate the density from the calculated area:

$\frac{N}{A} = \frac{1000}{2*10^{-15} } = 5*10^{17}$

In this way, the calculation represents that there is:

$5*10^{17} cells/cm^{2}$
