Wavelength =v/f therefore wavelength= (340m/s)/(490Hz)= .694m 

HOPE THIS HELPS! THANK YOU!

A group of students painted four cans, placed 500 grams of water in each can, and measured the temperature of the water as shown
inna [77]

B.The water molecules in the black can had the largest increase in average kinetic energy.

<u>Explanation:</u>

Here, black painted can absorbs more heat than the other color painted cans.

Black color absorbs all the heat and didn't reflect anything back, so it absorbs the most heat.

White color reflects all the heat, so heat absorbed by the white can is least.

When the black can absorbs heat then the water molecules in the can gets its maximum amount of kinetic energy so that the water molecules in the can collide with each other and also along with the walls of the can here, and so the average kinetic energy increases.

LenaWriter [7]

To solve this problem we will calculate the total volume of inhaled and exhaled water. From the ideal gas equation we will find the total number of moles of water.

An athlete at high performance inhales 4.0L of air at 1atm and 298K.

The inhaled and exhaled air contain 0.5% and 6.2% by volume of water, respectively.

During inhalation, volume of water taken is

V_i = (4L)(0.5\%)

V_i = 0.02L

During exhalation, volume of water expelled is

V_e = (4L)(6.2\%)

V_e = 0.248L

During 40 breathes, total volume of water taken is

V_{it} = (40L)(0.02L) = 0.8L

During 40 breathes, total volume of water expelled out is

V_{et} = (40L)(0.248L) = 9.92L

Therefore resultant volume of water expelled out from the lung is

\Delta V = 9.92L-0.8L = 9.12

From the body through the lung we have that

n = \frac{PV}{RT}

Here,

P = Pressure

R= Gas ideal constant

T= Temperature

V = Volume

Replacing,

n = \frac{(1atm)(9.12L)}{(8.314J/mol \cdot K)(298K)}

n = 0.373mol/min

Therefore the moles of water per minute are expelled from the body through the lungs is 0.373mol/min
