Convert: 110 km/h to m/s

Answers

Answer:

30.5555556 m/s

You can write like "30.56 m/s".

Answer:

Below

Explanation:

You can convert km/h to m/s by dividing the value by 3.6

      110 km/h / 3.6 = 30.5556 m/s

*not sure if your teacher wants you to round to sig figs for this but here it is anyways. Because 110 has 2 sig figs it would be :

    31 m/s

How many electrons can carbon accept from other atoms while bonding? (1 point)

two

six

eight

four

Answers

Answer: Four electrons

Explanation:

The number of electrons that can be accepted by carbon from other atoms while bonding is four. The correct option is D.

What is chemical bonds?

A chemical bond is what holds atoms in molecules together. Electrostatic forces between positively charged atomic nuclei and negatively charged electrons, the positions of which in space are determined by quantum mechanics, generate bonds.

Atoms form chemical bonds to strengthen their outer electron shells. The chemical bonding type maximizes the stability of the atoms that form it.

Carbon forms covalent bonds with other elements or carbon atoms. Carbon compounds are extremely diverse, with sizes ranging from one to thousands of atoms.

Because carbon has four valence electrons, it can form four covalent bonds to achieve a full outer energy level.

Thus, the correct option is D.

Two astronomers are viewing temperature data from each of the sun's layers, but the layers aren't identified. Describe one way the scientists can use temperature to identify which layer they are studying.(1 point) The highest temperatures are from the corona. The highest temperatures are from the corona. The lowest temperatures are from the photosphere. The lowest temperatures are from the photosphere. The lowest temperatures are from the core. The lowest temperatures are from the core. The highest temperatures are from the radiative zone.

Answers

Here we can study the different temperatures of each one of the layers of the sun.

We will find that the way that the scientist can identify which layer are they studying is "The lowest temperatures are from the photosphere."

A brief description of the temperature of each layer is:

Center of the sun: about 15 million K

Radiative Zone:  Goes from 7 million K to 2 million K.

Convection Zone: goes from 2 million K to 5800K

Photosphere: Is in average 5800 K , but there are sunspots with lower temperatures, of around 3800 K.

Chromosphere: goes from 4300 K to  8300 K

Corona: Around 2 million K.

So now we can analyze each of the options to see which ones make sense.

A) The highest temperatures are from the corona.

This is false, we can see that in the center and in the radiative zone we have larger temperatures than in the corona.

B) The lowest temperatures are from the photosphere.

While on average the temperature of the photosphere is larger than the smaller temperature of the chromosphere, in the photosphere we have the sunspots, and there we have the smallest temperatures in the whole sun, so this is true.

C) The lowest temperatures are from the core (or center).

Clearly false, there we have the larger temperatures.

D)  The highest temperatures are from the radiative zone.

Again false, the larger temperatures are in the center.

So the only true option is "The lowest temperatures are from the photosphere."

Answers

Answer:

Newton's third law: If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A. This law represents a certain symmetry in nature: forces always occur in pairs, and one body cannot exert a force on another without experiencing a force itself.

When is the pressure of the man on the ground more – lying position or standing
position? Explain.

Answers

Hi,

The man on the ground in standing position has more pressure. This is because when he stands, only his legs are in contact with the ground. While lying, his body is more in contact with the ground, therefore, he exerts less pressure.

To the point, a man standing position on the ground had more pressure.

More is the area of contact, less is the pressure efforted.
