A dolphin travels a distance 20 miles up the coastline in 153 minutes.If 1 mile is equal to 1609 meters,then what is the dolphin
Afina-wow [57]

Answer:

The dolphins average speed is 3.51 \frac{meters}{seconds}

Explanation:

First of all, the following rules of three should be applied:

  • If 1 mile is equal to 1609 meters, 20 miles are equal to how many meters?

distance=\frac{20 miles*1609 meters}{1 mile}

distance=32,180 meters

  • If 1 minute is equal to 60 seconds, 153 minutes is equal to how many seconds?

time=\frac{153 minutes*60 seconds}{1 minute}

time= 9,180 seconds

Speed ​​is a physical quantity that expresses the relationship between the space traveled by an object and the time used for it. That is, speed implies the change of position of an object in space within a certain amount of time and is calculated as:

speed=\frac{distance}{time}

So in this case the velocity is calculated as:

speed=\frac{32,180 meters}{9,180 seconds}

Solving, you get:

Speed= 3.51 \frac{meters}{seconds}

<u><em>The dolphins average speed is 3.51 </em></u>\frac{meters}{seconds}<u><em></em></u>

A mixture of gases contains 4.46 moles of neon (Ne), 0.74 mole of argon (Ar), and 2.15 moles of xenon (Xe). Calculate the partia
viva [34]

Explanation:

The partial pressure of an individual gas is equal to the total pressure of the mixture multiplied by the mole fraction of the gas.

Total pressure = 2atm

Mole Fraction = number of moles / total number of moles

Neon

Mole Fraction = 4.46 / 7.35 = 0.607

Partial Pressure = 0.607 * 2 = 1.214 atm

Argon

Mole Fraction = 0.74 / 7.35 = 0.101

Partial Pressure = 0.101 * 2 = 0.202 atm

Xenon

Mole Fraction = 2.15 / 7.35 = 0.293

Partial Pressure = 0.293 * 2 = 0.586 atm
