-What is the frequency of a 5.6 x 10^10 cm wave? <br> -What is the wavelength of 0.1096 Hz wave?
bixtya [17]
The equation that we will use to solve these two questions is:
c = lambda * f where:
c is the speed f the wave
lambda is the wavelength of the wave
f is the frequency of the wave

Question 1:
we want to find f
c is assumed to be the speed of light = 3*10^8 m/sec
lambda = 5.6 * 10^10 cm = 560 * 10^6 meters
Substitute in the equation to get f as follows:
3*10^8 = 560*10^6*f
f = (3*10^8) / (560*10^6) = 0.5357 Hz

Question 2:
we want to find lambda
c is assumed to be the speed of light = 3*10^8 m/sec
f is given as 0.1096 Hz
Substitute in the equation to get lambda as follows:
3*10^8 = lambda * 0.1096
lambda = (3*10^8) / (0.1096) = 2.737226*10^9 meters

What is necessary for the transport of oxygen by an erythrocyte?
Katyanochek1 [597]
I think the correct answer is Hemoglobin. Hemoglobin is necessary for the transport of oxygen by an erythrocyte. It is a protein molecule found in red blood cells made of four subunits; two alpha subunits and two beta subunits. This protein is responsible for carrying of oxygen to body cells and tissues, and carbon dioxide to the lungs.
