Hello there!
How is density different from weight and mass you say? It's simple!
1. Unlike weight, density is composed of mass and volume.
2. By dividing the mass over the volume, you can determine an object's density, while weight is the product of mass and gravity.
Hope this helps :) if so, can I get Brainliest?
Answer: Polar air mass is the large mass of air formed over land or water in higher latitudes. They are characterized by cold air.
Tropical air mass is the large mass of air that is formed 25 degrees latitude of the equator. They are characterized by warm air.
Explanation:
Polar air mass is known for cold air near earth's surface. Polar air mass takes place in cold regions like Arctic region.
Unlike tropical air mass, polar air mass brings cold and dry air weather in winter season.
Continental polar mass takes place in cold, stable and low humid areas like subpolar land. Whereas, maritime polar air mass forms over oceans which are cool and located in polar region.
Tropical air mass is characterized by warm to hot air. But, as this air mass move away from their latitude of origin, they get cooled down. This phenomenon mostly result in precipitation and storms in Unites States. This also shows that tropical air mass contains moisture. They are usually prone to sudden changes.
Continental tropical air mass is produced over desert areas of the world during summer, when its hot. While, maritime tropical air mass is produced over tropical and subtropical oceans and seas in the world.
Answer: C) The mass stays constant as it changed from a liquid to a gas
Explanation: Mass stays constant, it's never destroyed or created. It follows the law of conservation of mass.
Answer:
50 mg.
Explanation:
From the prescription, 240 ml amount is to be prepared containing 30 ml tussin syrup. As the frequency is 5 mL qid, it means 5mL of syrup is to be administered four times daily i.e. 20 mL daily. To calculate the amount of tussin taken daily,
<em> </em><em><u>30 mL tussin</u></em><em> = </em><em><u>X mL of tussin</u></em>
<em> 240 mL solution 20ml solution</em>
⇒ 2.5 mL of tussin
5 ml tussin contains 100mg guafenesin,
So,
⇒ 2.5 ml of tussin contains 100x2.5/5 = 50 mg guaifenesin
Answer:
neither accurate nor precise
Explanation:
Accuracy is the ability to give the same result on different measurements made under the same conditions or to give the desired result accurately, therefore, as observed in the image, the results are not accurate, since they are all different.
They are not precise either, since the precision is the degree of agreement between the independent results of a measurement, obtained under stipulated conditions, be it repeatability, reproducibility or intermediate.
