Homework Statement
I was given the oxygen binding curves for human and crocodile hemoglobins, with the crocodile having a higher affinity for oxygen at p50.
My questions are,
1) Crodocile hemoglobin does not bind BPG. Instead, deoxyhemoglobin preferentially binds to HCO3-. How does...

Homework Statement
Compute the area between the graphs of f(x) = 8sin(2x) and g(x) = 5sin(x)+3sin(2x) on the interval [0,pi/2]
Homework Equations
Area = Integral of [f(x)-g(x)]dx
The Attempt at a Solution
I first did f(x) - g(x) = 5sin(2x)-5sin(x)...after integrating, I got...
When there is not air resistance, potential energy is completely transformed into kinetic energy with each successive period. However, when air resistance is present, a fraction of the energy is lost and cannot be converted into kinetic energy.
Homework Statement
I'm given the position vs. time, velocity vs. time, acceleration vs. time, and energy vs. time graphs for a simple harmonic motion, and I want to know what would happen to those graphs if air resistance is included?

Homework Equations
w = 2 x pi x f = sqrt (k/m)
The Attempt at a Solution
Is this the equation I would...
Homework Statement
A block of mass 0.28kg is attached to a spring of spring constant 12N/m on a frictionless track. The block moves in simple harmonic motion with amplitude 0.2m. While passing through the equilibrium point from left to right, the block is struck by a bullet, which stops...
