Math (need formula)
I would be very appreciative if someone could provide me with the formula I would use to plug these figures into a graph. 3. A 2m length of board rests with one end on the floor and the other end on a small stack of bricks. A baseball is rolled up the board and back down again...

Physics
When a 0.50 kg-object is attached to a vertically supported spring, it stretches 0.10 m from the equilibrium position. Find k for the spring.

physics
Given x(t) = xm cos 2ðt/T for a spring with constant k and attached mass m sketch as a function of t, (a) the displacement x, (b) the velocity v, (c) the acceleration.

calculus(integral)
intergral 2x^2/(x^2+4x+8)

What figure from the history of philosophy section do you think might have some views that are similar, or at least relevant, to your own?

physical chemistry
find the ph of the solution that results from the addition of 25ml of 0.1mol/l NaOH solution to 50ml of 0.1mol/l HCL solution?

Chemistry
A flask partially full of liquid water is heated to boiling and capped cold water is poured over the flask. The water boils even more vigorously explain

physics
Quartz has a refractive index of 1.54. If light from a HeNe laser impinges on an air/quartz interface at an angle of 22.5 degrees, what is the angle of refraction?

physics
Calculate the frequency in hertz, wavelength in nm, and the velocity in m/s of light inside a material with a refractive index of 1.39. In vacuum, the light has a wavelength of 514.5nm
