1. You are pushing a heavy shopping cart full of water bottles with a constant force. The shopping cart has
mass of 250 kg and it is accelerating down the aisle at 0.20 m/s? How much force are you exerting?

Answers

Answer:

F = 50 N

Explanation:

Given data:

Mass of car = 250 Kg

Acceleration of car = 0.20 m/s²

Force required = ?

Solution:

Formula:

F = m×a

F = applied force

m = mass

a = acceleration

Now we will put the values in formula.

F = 250 Kg × 0.20 m/s²

F = 50 Kg.m/s²

Kg.m/s² = N

F = 50 N

can you identify an atom without knowing numbers of neutrons in it?

Answers

Answer:

Explanation:

We cannot identify an atom without knowing numbers of protons in the atom.

The number of neutrons is the amount of neutrally charged particles in an atom. These subatomic particles occupy the dense nucleus with the protons.

To determine an atom, we use their atomic numbers. Atomic number is the number of protons in an atom. Protons are the positively charged particles in the atom. The periodic table of elements is arranged by the atomic number of an element.

When an atom is unstable, what will happen?

Answers

Answer: Unstable atoms will lose neutrons and protons as they attempt to become stable, atoms the binding energy is not strong enough to hold the nucleus together

SEP Engaging in Argument Use the phase diagrams for CO2 and H2O in the Experience Notebook. Theaters sometimes use dry ice (solid CO2) to produce dense clouds of smoke like fog on stage. A classmate claims that the phase diagrams of H2O and CO2 show that it would not be practical to use H2O for this purpose. Do you agree with the classmate’s claim? Cite reasons to support your argument.

Answers

Answer:

Agree (see explanation)

Explanation:

I do agree with this statement of practicality. According to my research and viewership of phrase diagrams for both substances, water enters a similar form of “smoke” or “steam” at incredibly hot temperatures usually secluding to temperatures of over 200 degrees Fahrenheit (100 degrees Celsius) versus carbon dioxide of which enters this state at room temperature (60-70 degrees Fahrenheit). In order for either of these events to occur in this form, both must undergo procedures of sublimation where solids transfer directly from solids to gases, skipping the liquid state. Water contains ionic hydrogen bonds of which are incredibly strong particle arrangements, therefore requiring much higher temperatures to divide and individualize these particles forming high pressure and kinetic energy. Since carbon dioxide is formed of covalent bond ship, the intermolecular forces are relatively weak making the process of sublimation quite instant when this substance experiences exposure to specific temperatures, typically temperatures that we consider “normal”.

Hopefully I helped anyone understand this, and I apologize for being late to this question.....very late.

You have a flexible helium balloon filled with 0.100 mol of gas that is 2.10 L at a certain temperature and pressure. If you deflate the balloon at, constant temperature and pressure, so that it is now only 0.700 L, how many mol of gas are remaining in the balloon?

Answers

Answer:

0.033 mole

Explanation:

The following data were obtained from the question:

Initial mole (n1) = 0.1 mol

Initial volume (V1) = 2.1 L

Final Volume (V2) = 0.7 L

Final mole (n2) =?

Since the temperature and pressure is constant, then the number of mole remaining in the balloon can be obtained by using the following formula as illustrated:

V1 /n1 = V2 /n2

2.1/0.1 = 0.7/n2

21 = 0.7/n2

Cross multiply

21 × n2 = 0.7

Divide both side by 21

n2 = 0.7/21

n2 = 0.033 mole

Thus, 0.033 mole of the gas is remaining in the balloon.

When Jeremy returned home after vacation, he noticed that his new plant had not grown. His mother, a florist, told him that it was because the plant was not getting enough sunlight. He moved his plant closer to the window to get more sunlight. How can Jeremy best support the idea that his plant needs more sunlight? Ask his mother to make the plant better. Wait and see what happens to the plant. Remove the plant from direct sunlight after a week. Ask his science teacher at school what she thinks could be the reason.

Answers

Answer:

Wait and see what happens to the plant.

Explanation:

The best course of action for Jeremy would be to wait and see what happens to the plant after moving it closer to the window to get more sunglight.

If the plant grows after observing it for some times, he can conclude that light has been a major hindrance to the growth and more sunlight would benefit the plant. If the observation is otherwise, then Jeremy can conclude that the lack of growth observed is not due to light.

Answer:

remove the plant from direct sunlight after a week

Answers

Answer:

Sand and water

Oil and sand

Explanation:

A mixture, has rightly stated in this question, is a substance composed of two or more substances combined physically rather than chemically. In a mixture, each constituent retains its chemical properties i.e. the chemical properties of none of the substances in a mixture is altered. This serves as the basis for the physical separation of a mixture.

One example of mixture has been given in this question i.e salt and sugar combined together in a bowl. This represent a mixture because the sugar is not chemically combined to the salt, hence, each can easily be separated. This is the same for any other mixtire. More examples include:

Sand and water

Oil and sand

Salt and water (salt solution)

Petroleum or crude oil

Answers

Explanation:

Using a derivative of the combined gas law we can explain what is happening in both instances.

Assuming that the volume is constant which is predicated on the bottle shape and structure, the pressure of a given mass of gas varies directly with the absolute temperature.

As temperature increases, the pressure also increases and vice versa.

The first bottle at a higher temperature has a higher pressure of gas. The second bottle at a lesser temperature has a reduced pressure inside.

Choose the mole ratio below that is INCORRECT based on the given balanced equation:

2 C2H5OH + 7 O2 --> 4 CO2 + 6 H2O

O 2 moles C2H5OH = 4 moles CO2

O 7 moles O2 = 2 moles C2H5OH

O 4 moles CO2 = 4 moles O2

O 6 moles H2O = 7 moles O2

Answers

Answer:

4 moles CO₂ = 4 moles O₂

Explanation:

The reaction equation is given as;

2C₂H₅OH + 7O₂ → 4CO₂ + 6H₂O

The incorrect mole ratio from the relationships shown is;

4 moles CO₂ = 4 moles O₂

Number of moles of CO₂ = 4

Number of moles of O₂ = 7

So, the right expression is;

4 moles CO₂ = 7 moles O₂

Each colony now had productive farms and new towns growing as trading posts. Britain profited from these by taxation. Everything grown, bought or sold in the American Colonies was somehow taxed by Britain.Another effect was the British Colonies became destinations for thousands of immigrants from England and elsewhere in Europe. Wealthy Europeans were eager to claim new land for plantations or make fortunes from trade in the new cities. Middle-class European farmers hoped they could get new farmland of their own. Many poor English and Scots-Irish settlers hoped they could find better lives in America working as indentured servants and hopefully purchasing land of their own someday.Every new English colony was a new disaster for the Native Americans. The forests they hunted were cut down to make way for farms and plantations. More and more tribes became pushed off their land, either being cheated by false negotiations, or forced out with violence. When tribes fought back, the English settlers would retaliate harshly with gunfire and arson, burning entire villages to the ground. Worse still was the invisible killer that British settlers brought with them: diseases like smallpox and plague, which spread among native tribes quickly and for which they had no immunity or treatments. Sometimes, colonists would give infected blankets to natives to spread diseases on purpose. Ultimately for the native tribes, the effects of British settlement in America were tragic and irreversible. By the mid 1700s, most tribes had nearly vanished from the Atlantic coast.The final effect of the British Colonies was the introduction of slavery to North America. The first kidnapped Africans in the American Colonies were brought to Jamestown as slaves to work in the new tobacco plantations. Slavery would spread throughout the new colonies, with cities as far north as New York being used as trading posts for slave auctions. Mainly however, slavery was much more concentrated in the southern colonies, which had large tobacco and rice plantations requiring many laborers. In the Southern Colonies, African people were simply considered property. Laws in Maryland only referred to Africans in terms of planters property rights. A Virginia law in 1642 punished people for hiding runaway slaves or indentured servants. Free blacks were eventually permitted to live and own property in northern colonies, and slavery in the north slowly became outlawed. In the south, however, the plantation economies of the colonies depended almost completely on slave labor.17.
