well, i didnt think of that, if thats the case, v=(-1/3)t+4 Sub in t=6 v=(-1/3)(6)+4 v=(-6/3)+4 v=-2+4 v=2 Hope you read this before you sleep =\
Sub in t=6 into the formula v=-1/3t+4 v=-1/3(6)+4 v=-1/18+4 v=-1/18+72/18 (4 is the same as 4/1 and when multiplied by 18, 72/18) v=71/18
B) Fault block mountains Happens when two plates collide, and force the rock up.
if you rearrange the question it becomes y=8x-8 Using y=mx+b, with m as your slope, your slope is 8
I typed exactly what is said on the question sheet. Answer given is 5.47*10^15 photons/s As each photon strikes the electron, it is absorbed and then any excess energy is then re-radiated in the form of x-rays, from what i understand, i need to find the remaining energy (since...
A cathode ray tube operates at 80 kV with a current of 875 uA. Calculate the a)Intesity (# of photons per second f the x-rays b)Minimum wavelength of the x-rays produced by the CRT thanks in advance
W=FD W=(400N)(3.0m) W=1200N I dont really get the 1250N car thing. Unless you also need friction, but i need the coefficent for that.
Using the point slope formula m=(y2-y1)/(x2-x1) m=([1/2]-[1/2])/([-5]-[-9]) m=0/4 m=0 In other words, this is a horizontel line, with a slope of 0 m=rise/run
Yes, if the particle is not in motion, it will not experience a magnetic force (faraday's law) Yes to 2 too, using the third hand rule, fingers pointing in the direction magnetic field (north to south), thumb pointing in the direction of particle movement(in this case nowh...
