Hey, I'll try to help with what I know. It might help you to know this: specific gravity of a fluid = density of fluid/density of water.

hey, God...Thank you sooo much. It took me a while to notice it actually. :)

Hi everyone, I hope you can help me out with this question as my exam is tomorow. Homework Statement A 355 mL soda can with diameter=6.2 cm has a mass of 20g. If it is half full with water, and it is floating upright on water, what length of the can is abover the water level...

\piHi everyone, I hope you can help me out with the following question. I am mainly confused about the sign Homework Statement A block in SHM with T= 4.0 s and A=0.1 m. How long does it take the object to move from x=0 m to x= 0.06 m. Homework Equations x=Acos(wt + \phi) w=2pi/T...

all right, thank you for teaching me. i was really stuck before.

hi, i am still confused. i put - on the s because the displacement is negative. but sicne the initial position is h, then it would make sense to write it that way. thanks! ok, so, for equation 2 (object going up), would it be like this: y=vt-g/2t^2 where x=y? i hope i got it right...

Homework Statement The problem is that basically, if an object is thrown up with a certain initial velocity (v), and an object at height h directly above the first object falls (intial velocity=0), write an equation for the position they collide. (position denoted as x) Homework Equations...

thank you so much!:approve: salam

hi everybody, Homework Statement A +2 C charge is 20cm to the right of a -3 charge. What is the electric field on the line excatly halfway between the two charges? Homework Equations E = kq/d^2 The Attempt at a Solution force of attraction; therefore vector of -3 charge would...
