well that would be proportional to the mass right? so if r2 is 5x in mass then r1 is 1/5(mass)? set up my equation to isolate r to get the radius...

Homework Statement Two spheres are cut from a certain uniform rock. One has a radius 4.50cm. The mass of the other is 5 times greater. Find its radius Homework Equations r1 = 4.50cm r2 = ? when mass is 5x greater The Attempt at a Solution Looking at this problem I first thought...

yes it is-so how would i approach the problem?

ok I am not getting the answer which is suppose to be 6850 Pa. anyone able to help me out here??

does anyone how delta p and gauge pressure are related? i need to find pressure of fluid, and delta p is only unkown variable i have...so i know i am solving for it, right?

oh wow...my bad...never mind -_- thanks!

hmm i did the same thing-ill check my settings then. oh well. the important thing is that my setup for the prblm was right! =)

i have been trying it all day and just did it again. now I am getting 2177777 how did u put in ur calc?

Air Bubbles and Terminal Velocity--> why is my answer wrong? (all work shown) Homework Statement Air bubbles of 1.0mm radius are rising from a scuba diver to the surface of the sea. Assume a water temp of 20C. a) If viscosity of water = 1.0 X 10-3 Pa.s, what is the terminal velocity of...

Homework Statement Question Details: A hypodermic syringe is attached to a needle that has an internal radius = .300mm and Length=3.00cm The needle is filled with solution of viscosity= 2.00 x 10^(-3) Pa.S And injected at a vein with a gauge pressure of 16mm Hg What must the pressure of...

The speed of ocean waves depend on their wavelength \Lambda (measured in meters) and the gravitational field strength g (measured in m/s^2) in this way: v = \LambdaPgQ where K is a dimensionless constant. Find the values of the exponents P and Q

are you sure? i was workin on this with my prof and he told me not to take the log; that's what i thought of doing initially and i have no numerical values for the equations; its all dimension analysis

Homework Statement Speed of an ocean wave depends on the wavelength \lambda in meters and gravitational field. (see equation below). Find values of P and Q. K is a constant and has no dimensions Homework Equations V = K\lambdaPgQ The Attempt at a Solution V=velocity, which is...

Homework Statement Assuming ideal frictionless condition for an apparatus (a table with a block in the middle and one hanging from each side, what is: the accelerarion of the system if the mass for each is .25 kg .50 kg and .25 kg (mass 1,2, and 3 respectivley) mass 3 is on the top and mass...

^the force is directed right towards the middle of A and B coming from the right side. so mass times accl will give me the force? that would be 82.5 and i know that is incorrect because the answer for b should be around 173 N
