The pressure of a cylinder with the following dimensions: radius 13.9 cm and height 34 cm; has a pressure of 172.9 kPa. If the pressure is reduced to 1.75 atm, what will be the volume of the gas inside the cylinder?

Answers

Answer:Experience has shown that several properties of a gas can be related to each other under certain conditions. The properties are pressure (P), volume (V), temperature (T, in kelvins), and amount of material expressed in moles (n). What we find is that a sample of gas cannot have any random values for these properties. Instead, only certain values, dictated by some simple mathematical relationships, will occur.

How do the properties of air influence weather?

Answers

Temperature refers to how warm or cold air is, and the density of the air is how many molecules are packed into a certain space of air. ... But, air pressure also affects temperature - the more those molecules bump into each other, the more heat they generate.
Rising Air creates low pressure while sinking air creates high pressure. WIth high pressure, sinking air suppresses weather development. High air pressure produces clear sky, dry and stable weather. In a low pressure zone, wind is circulated onwards and upwards rapidly. As a result, air rise and cools. Clouds and precipitate are formed

Abiotic factors include the non living components of the environment.
For example- Temperature, humidity, and rainfall.
Desert biome is mainly considered as a part of drylands. It is characterised by extremely low humidity. Average rainfall in this biome is less than ten inches. This results in scarcity of water. It experiences extremely high temperature and is frequently windy.

In a recent hockey game, one player (m=100kg) was moving at a velocity of 8 m/s when he ran into another player (m=300kg) who was at rest (v=0m/s). After the collision, the two players were stuck together (moving with the same velocity). What was their velocity after the collision?

Answers

At first you need the displacement/distance from the point he started to run to the other player
Buttttttttttt if they were at rest because the force was balanced it could be
0m/s^2
Or the other way around
25m/s^2

Their velocity after the collision was 2 m/s.

What is principle of conservation of momentum?

According to the principle of momentum conservation, momentum is only modified by the action of forces as they are outlined by Newton's equations of motion; momentum is never created nor destroyed inside a problem domain.

Given parameters:

one player (m=100kg) was moving at a velocity of 8 m/s initially.

Another  player (m=300kg) who was at rest (v=0m/s) initially.

After collision they stuck together and let the velocity of them is v.

According to principle of conservation of momentum,  total momentum remains conserved.

total initial momentum = total final momentum

100×8 + 300×0 = (100 + 300)v

400v = 800

v = 2.

Hence,  their velocity after the collision was 2 m/s.

Describe which of Earth's subsystems are involved when a hurricane passes through an area. Explain how these different subsystems affect one another.

Answers

Answer:

Explanation:

The Earth is made of several subsystems or "spheres" that interact to form a complex and continuously changing whole called the Earth system. Scale

Processes operating in the Earth system take place on spatial scales varying from fractions of millimeters to thousands of kilometers, and on time scales that range from milliseconds to billions of years.

Examples of instantaneous - breathing; rotation of the Earth; earthquake

Examples of long term - making coal; plate tectonics

Cycles

The Earth system is characterized by numerous overlapping cycles in which matter is recycled over and over again. Cycles involve multiple spheres and systems interactions.

Examples of cycles: day and night; rock cycle; seasons

What are air masses, and how do they work?

NEED HELP ASAP!

Answers

Answer:

Need help? I'll give it to you!

Explanation:

Air masses are formed when air stagnates for long periods of time over a uniform surface. The characteristic temperature and moisture of air masses are determined by the surface over which they form. An air mass acquires these attributes through heat and moisture exchanges with the surface.

Also known as air-flow mattresses, alternating pressure mattresses relieve and redistribute pressure through a dynamic lying surface. Alternating pressure sore mattresses are assembled with a row of lateral air cells that constantly alternate. Hope it helps
