Physics
A proton accelerates from rest in a uniform electric field of 620 N/C. At one later moment, its speed is 1.30 Mm/s (nonrelativistic because v is much less than the speed of light). (a) Find the acceleration of the proton. m/s2 (b) Over what time interval does the proton reach ...

Biology
I don't understand how to do this at all!! I've been Googling the past hour and I just don't get it. My teacher won't respond and my exam is tomorrow. I get that we cleave with an acid and then we can do amino acid analysis. The entire protein can be pieced tog...

Physics
By what factor would you have to decrease the tension in a stretched string in order to decrease the wave speed by a factor of 3.5? I know that v = sqrt(T/u) but am confused as to what to do?

Physics
A particle executes simple harmonic motion with an amplitude of 9.00 cm. At what positions does its speed equal two thirds of its maximum speed? I got: v2 +ω^2x^2 =ω^2A^2 vmax =ω A and v = ωA/2?

Your hospital has just received a reimbursement rejection from the fiscal intermediary for two outpatient procedures that were performed on the same day. This rejection was probably generated by

Physics
The water in a river flows uniformly at a constant speed of 2.53 m/s between parallel banks 69.8 m apart. You are to deliver a package directly across the river, but you can swim only at 1.74 m/s. (a) If you choose to minimize the time you spend in the water, in what direction...
