Write one paragraph!!!!!reasons why the minimum wage should be increased.
Answer:
There are pros and cons, I will explain mostly pros. After all the pros outweigh the cons.
Explanation:
Increasing the minimum wage can be letting people work less or earn more. This can have a major impact on the economy in America. It can reduce poverty within some families households. A con concerning this though is that people who work for low pay can lose their jobs and their family can become poor. It can also affect the federal minimum wage.
Hopefully this helped you out a lot. Please make sure to make my answer brainliest. Have a great rest of your day or night
Answer:
Minimum wage increases allow people to work less and earn more. This may have a significant influence on the American economy. It can help some families get out of poverty. People who labor for little compensation risk losing their employment and being unable to provide for their families, which is a drawback. As a result, the federal minimum wage may also be affected.

Maria walked on a beach made mostly of sand. She walked barefoot
on the beach early in the morning, and the sand was cool. When she
walked in the same area in the afternoon, the sand was hot.
Which statement best describes why the temperature of the sand
increased?
The statement that the atoms in the sand were moving more quickly best describes why the temperature of the sand is increased. The relationship between kinetic energy and temperature is explained here.
What is the relationship between kinetic energy and temperature?The temperature of a body is directly proportional to the kinetic energy. The energy acquired by those molecules which are in motion is called the kinetic energy.
The radiation of the sun falls on a number of objects on our surroundings. The objects absorb this energy till afternoon due to which they become hot.
When Maria walked in afternoon, the sand was hot as its particles have gained the kinetic energy due to which they move rapidly from one place to another. So that the sand feels more hot in the afternoon.
Thus the atoms in the sand were moving more quickly best describes the increase in temperature of the sand.

Explanation:
Both the stomach and the small intestine are involved in the digestion of food.
The churning of food by stomach muscles and peptidase enzymes in the small
intestine both break food molecules into smaller molecules.
Which statement best describes changes to food during digestion?
Answer: I think the answer is The muscle contractions result in physical changes, while the action of the peptidase results in chemical changes.
Explanation: Because the muscles would make the food smaller and the enzymes have a chemical change to it because it changes the molecules in the food.
The chemical processes in food digestion results in the formation of new
substances.
The statement that best describes the changes in food during digestion is;
The churning of the food is a physical process, which results in physical changes while the peptidase results in chemical changes of the food.
Reasons:
The given processes in the digestion of food are;
Stomach: Food churning is the process by which the small intestine vigorously turns ingested food.
Small intestine: The action of the peptidase enzyme is to increase the rate of the digestion of food.
Therefore;
The churning of the food is a physical process, which results in physical changes while the peptidase results in chemical changes of the food.

What effects do winds patterns have on climate
Prevailing winds bring air from one type of climate to another. For example, warm winds that travel over water tend to collect moisture as they travel; the water vapor in the air will condense as it moves into colder climates, which is why temperate coastal areas often receive heavy rainfall.

In carbon dioxide, London dispersion forces are the only intermolecular forces of
attraction.
a. TRUE
b. FALSE
Answer:
true
Explanation:
CO has two C-O bonds. The dipoles point in opposite directions, so they cancel each other out. Thus, although CO₂ has polar bonds, it is a nonpolar molecule. Therefore, the only intermolecular forces are London dispersion forces.
A class investigated the reactivity of four metals by dropping little pieces of the
metals into solutions of their salts.
When there was a reaction they recorded a `Y’, when there was no reaction they
recorded an `N’.
Here is their table of results.From their results, which is the least reactive metal?
The least reactive metal is lead, since it reacted with none of the salt solutions.

Calculate the specific heat of glass from the following data. The temperature of a piece of glass with a mass of 65 g increases by 26°C when it absorbs 840 J of heat energy.
Answer:497J/kg/K
Explanation:
Use the equation: Q=mS◇T
According to specific heat capacity, the specific heat of glass is 0.4970 J/gK.
What is specific heat capacity?Specific heat capacity is defined as the amount of energy required to raise the temperature of one gram of substance by one degree Celsius. It has units of calories or joules per gram per degree Celsius.
It varies with temperature and is different for each state of matter. Water in the liquid form has the highest specific heat capacity among all common substances .Specific heat capacity of a substance is infinite as it undergoes phase transition ,it is highest for gases and can rise if the gas is allowed to expand.
It is given by the formula ,
Q=mcΔT
Substituting values in above equation, c=Q/mΔT, C=840/65×26=0.4970 J/gK.
Thus, the specific heat of glass is 0.4970 J/gK.
