(a) Red light has a wavelength of roughly 700 nm. What is the wavelength in m? ball park 10.10' (b) What is the wavelength of re
joja [24]

Explanation:

1)

a) Wavelength of red light = 700 nm

1 nanometer = 10^{-9} meter

Wavelength of red light in meter will be:

=700 nm=700\times 10^{-9} m=7.00\times 10^{-7} m

b) Wavelength of red light = 7.00\times 10^{-7} m

1 meter  = 39.3701 inches

Wavelength of red light in inches will be:

7.00\times 10^{-7} m=7.00\times 10^{-7}\times 39.3701 inches

=2.7559\times 10^{-5} inches

2)

Value of distance given = 90.123 km

1 km = 3280.84 feet

90.123 km=90.123 \times 3280.84 feet=295,679.1433 feet

1 foot = 0.1515152 chain

295,679.1433 feet=295,679.1433\times 0.1515152 chain

=44,799.88453 feet\approx 4.48\times 10^4 chains

Value of distance in chains:

90.123 km=4.48\times 10^4 chains

Answer:

Pressure

Explanation:

The variable that describes how often the particles in a sample of gas collides with each other and the walls of the container is the pressure.

The pressure of a gas is the combined force with which the gas molecules bombard a unit area of the wall of the container i.e the sum of all the tiny pushes on the unit area of the wall of the container.

The various units of gas pressure atmosphere, millimeters of Hg, torr, pascal, newton per meter squared.
