Write one paragraph!!!!!reasons why the minimum wage should be increased.

Answers

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.

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.

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.

Answers

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.

Find the number 1Bacchus, on a certain occasion, found his old schoolmaster and foster-father, Silenus ,missing. The old man had been drinking, and in that state wandered away, and was found by some peasants, who carried him to their king, Midas. Midas recognized him, and treated him hospitably, entertaining him for ten days and nights with an unceasing round of jollity.2On the eleventh day he brought Silenus back, and restored him in safety to his pupil. Whereupon Bacchus offered Midas his choice of a reward, whatever he might wish. He asked that whatever he might touch should be changed into gold. Bacchus consented, though sorry that he had not made a better choice.3Midas went his way, rejoicing in his new-acquired power, which he hastened to put to the test. He could scarce believe his eyes when he found a twig of an oak, which he plucked from the branch, become gold in his hand. He took up a stone; it changed to gold. He touched a sod; it did the same. He took up an apple from the tree; you would have thought he had robbed the garden of the Hesperides. His joy knew no bounds, and as soon as he got home, he ordered the servants to set a splendid repast on the table. Then he found to his dismay that whether he touched bread, it hardened in his hand; or put a morsel to his lip, it defied his teeth. He took a glass of wine, but it flowed down his throat like melted gold.4In consternation at the unprecedented affliction, he strove to divest himself of his power; he hated the gift he had lately coveted. But all in vain; starvation seemed to await him. He raised his arms, all shining with gold, in prayer to Bacchus, begging to be delivered from his glittering destruction. Bacchus, merciful deity, heard and consented. Go, said he, to River Pactolus, trace its fountain-head, there plunge yourself and body in, and wash away your fault and its punishment. He did so, and scarce had he touched the waters before the gold-creating power passed into them, and the river sands became changed into gold, as they remain to this day.5Thenceforth Midas, hating wealth and splendour, dwelt in the country, and became a worshipper of Pan, the god of the fieldsQuestion 2 )Which sentence BEST develops the theme?
