Answer: The correct answer is molecules.

Explanation:

The intermolecular forces help to hold the molecules together. The force of attraction between the molecules is called intermolecular forces.

In the solid state, the molecules are tightly packed. There is a strong force of attraction between the molecules.

In the liquid state, the molecules are loosely packed in comparison to the solid state.

In the gaseous state, the molecules are more loosely in comparison to the liquid state. There is a weak force of attraction between the molecules.

Therefore, intermolecular forces hold together molecules.

Answer:

The coefficient is 0.90

Explanation:

Drawing a diagram makes thing easier, we will assume that the acceleration tends to zero because it start barely moving.

$-F_s+mg*sin(\theta)+F=0\\F_s=57.1kg*9.8m/s^2*sin(28.3)+177N\\F_s=442N\\F_s=\µ*N\\N=m*g*cos(\theta)\\N=57.1*9.8*cos(28.3)=493N\\\\\µ=\frac{442N}{493N}=0.90$

What is the modern<br> Jatomic theory?

torisob [31]

<u>Answer:</u>

The modern atomic theory has given by "John Dalton and framed postulates".

<u>Explanation:</u>

The fundamental role of atoms in chemistry is established by the modern theory of atoms mentioned in 1808 for the first time by an English scientist named John Dalton. This consists of three sections such as all matter is composed of atoms, atoms of the same element are the same while atoms of different elements are different, atoms combine to form compounds in full-number ratios.

The unique characteristic of the "number of protons" is that all atoms of the same compound share. While the atoms of the same element i.e having a similar number of protons can have different numbers of neutrons and such elements are called isotopes.

When and where did the first nuclear reactor generate electricity

masha68 [24]

<h2>Answer: On December 20th, 1951 in Idaho, United States. </h2>

The world's first experimental nuclear power plant was the Experimental Breeder Reactor Number One (EBR-I), which was built in a desert in Idaho, United States.

This reactor made history when, on December 20th, 1951, four 200-watt light bulbs were illuminated by means of atomic energy, specifically by nuclear fission reaction.

To solve the problem it is necessary to apply the concepts related to Kepler's third law as well as the calculation of distances in orbits with eccentricities.

Kepler's third law tells us that

$T^2 = \frac{4\pi^2}{GM}a^3$
