no i don't know the answer, i have to type them in online, and then it tells me if I'm right or wrong. the thing is, that i have done the same calculations with the entire number, not in scientific form, i pretty much put them that way in this thread for the sake of saving time writing long...
Hi I cannot get this problem for the life of me and I have no idea why
Four charges q1 = q3 = -q and q2 = q4 = +q, where q = 5 µC, are fixed at the corners of a square with sides a = 1.3 m
Calculate the x- and y-components of the net electric field at the midpoint M of the bottom side of...
Hi i really do not know how to do this. any help is much appreciated. thanks!
Homework Statement
A projectile is shot out at 45° with respect to the horizon with an initial velocity of Vx = Vy = Vxy. When is the earliest time, t, that the velocity vector makes an angle of 30° with respect to...
ok well on mass 1 i got the normal force going up, mgcos30 going down, tension going to the right and mgsin30 going left. on mass 2 i got tension up and mg down. so this would mean that T=mgsin30 or T=mg, but those are not right. there's something else that i am not seeing
i believe that if the mass isn't moving, its net force is 0 because there is no acceleration. I'm just not sure what to use as my equations. this type of problem has always confused me for whatever reason.
hi i cannot seem to figure this problem out at all. any help is appreciated.
A 30 kg block (M1) is placed on a frictionless plane that inclines at a 30° angle with respect to the surface of Earth. This block is connected to another 20 kg block (M2) via a weightless rope over a frictionless...
