Answers

Answer:

wind is just high and low pressure of air, when a high pressure comes and crashes into a low pressure air pocket than it can form a wind storm.

Explanation:

The Uneven heating of the Earth's surface. Earth's rotation and unequal heating of the Earth's surface. air pressure towards regions of lower air pressure. ... air moving from areas of high pressure to areas of low pressure.

This is what will most likely cause a sudden wind to start blowing.

Which organism in the food chain is
responsible for transforming radiant
energy into chemical energy?

Grass->Prairie Dog -> Coyote -> Soil Bacteria

Answers

Answer:

The organism in the food chain responsible for transforming radiant energy into chemical energy is;

Grass

Explanation:

Radiant energy is the energy present in electromagnetic waves which carry photons that may be considered as energy packets. It is an energy present in the Sunlight, which is an electromagnetic waves, and it is the energy in the electromagnetic waves that plants convert to chemical energy for food in the process known as photosynthesis as follows;

6CO₂ + H₂O + Radiant energy → C₆H₁₂O₆ + 6O₂

Therefore the organism in the food chain responsible for transforming radiant energy into chemical energy is the plant, grass

A tank for storing liquid as a base of area 1.5 meters square. What is the pressure on the base of the tank when it contains water weighting 4500n

Answers

Answer:

3000 Nm^2

Explanation:

We must remember that pressure is defined as force per unit area.  

We have been given the following information in the question;

Area of the tank= 1.5 m^2

Weight of water in the tank = 4500N

And;

P = F/A

F= force

A = area

P = 4500 N/1.5m^2

P= 3000 Nm^2

There are only 90 naturally occurring elements on Earth but there are millions of different substances explain how this is possible and describe how it applies to at least three examples

Answers

Answer:

See explanation

Explanation:

While it is true that there are only about 90 naturally occurring elements, these elements are capable of combining with each other to form millions of substances.

Most of the substances that we see around us today result from a combination of one or more of these naturally occurring elements.

Let us look at three examples;

The carbohydrate in food is composed of carbon, hydrogen and oxygen

The stainless steel materials we use are composed of iron, carbon and other trace elements

Glass is made up of silicon, oxygen and other elements

Only 90 naturally occurring elements capable of combining with each other to form millions of substances.

Compounds:

When two or more elements combine in a certain ratio to form a molecule.

For example-

Water is made up of two hydrogen and one Oxygen ration is 2:1.

If hydrogen and Oxygen combine inn 2:2, they for Hydrogen peroxide.

Water gives life and Hydrogen peroxide can kill a person.

Other examples are,

The carbohydrate in food is composed of carbon, hydrogen and oxygen.  The stainless steel is made up of  iron, carbon and other trace elements.  Glass is composed of silicon, oxygen and other elements.

Therefore, only 90 naturally occurring elements capable of combining with each other to form millions of substances.

A gas at a pressure of 360 torrs and a volume of 750 ml. If the pressure becomes 1.5 atm what is the new volume?

Answers

Answer:

V₂ = 236.84 mL

Explanation:

The relation between pressure and volume is inverse.

We can write it as follows :

[tex]P_1V_1=P_2V_2[/tex]

We have,

P₁ = 360 torrs, V₁ = 750 mL, P₂ = 1.5 atm = 1140 torr.

So,

[tex]V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{360\times 750}{1140}\\\\V_2=236.84\ mL[/tex]

So, the new volume of the gas is 236.84 mL.

Determine el número de moles presentes en una esfera de titaniode 0.5 cm de radio, sabiendo que la densidad del titanio es de 4507kg/m³. =433

Answers

Answer:

0.0493 moles de Titanio

Explanation:

Primero, debemos hallar el volumen de la esfera. Usando la densidad podemos hallar la masa de titanio y usando la masa atómica encontraremos las moles de titanio:

Volumen de la esfera:

Volumen esfera  = 4/3π * Radio³

Volumen = 0.5236cm³

En m³ (1m³ = 1x10⁶cm³):

0.5236cm³ * (1m³ / 1x10⁶cm³) = 5.36x10⁻⁷m³

Masa en gramos:

5.36x10⁻⁷m³ * (4507kg / m³) = 2.36x10⁻³kg * (1000g / 1kg) = 2.36g de Titanio

Moles -Masa molar Ti: 47.867g/mol-:

2.36g de Titanio * (1mol / 47.867g) =

0.0493 moles de Titanio
