Homework Statement A small solid sphere of mass M0, of radius R0, and of uniform density ρ0 is placed in a large bowl containing water. It floats and the level of the water in the dish is L. Given the information below, determine the possible effects on the water level L, (R-Rises, F-Falls...

It is online homework and the program said all my answers were correct.

Nevermind! I was able to get this one as well. My answer turned out to be 1) true 2) equal to 3) true 4) greater than 5) true

Nevermind! I was able to figure out the answer. It was: 1) equal to 2) less than 3) less than 4) true 5) greater than 6) greater than

Thank you for your help. I got it by using the equation I posted, I was just was confusing r as the radius not as the distance from the axis.

Homework Statement A small mass M attached to a string slides in a circle (x) on a frictionless horizontal table, with the force F providing the necessary tension (see figure). The force is then increased slowly and then maintained constant when M travels around in circle (y). The radius of...

Homework Statement A pulley with mass Mp and a radius Rp is attached to the ceiling, in a gravity field of 9.81 m/s2 and rotates with no friction about its pivot. Mass M2 is larger than mass m1. The quantities Tn and g are magnitudes. 1) The magnitude of the acceleration of m1 is ...

Homework Statement Three small spherical masses are located in a plane at the positions shown below. The masses are Q=0.700 kg, R=0.400 kg, and S=0.800 kg. Calculate the moment of inertia (of the 3 masses) with respect to an axis perpendicular to the xy plane and passing through x=0 and y=-3...

Nevermind! I figured it out, thank you all so much for you guidance in this problem.

I understand where this equation comes from, but I am not sure how you would go about solving that for θ. I don't understand at all what I would use to solve for r or how this would result in a quadratic equation. I am struggling with every aspect of this problem.

Homework Statement A mass of 3.50 kg is suspended from a 1.59 m long string. It revolves in a horizontal circle as shown in the figure. The tangential speed of the mass is 2.99 m/s. Calculate the angle between the string and the vertical. Homework Equations a_c = v^2/r F = m*a_c...

Thank you so much for help, i got correct

If there is no acceleration then there should be no net force. So that would mean that for both 2 and 3 they would be equal to. Does that seem correct?

Homework Statement In the figure, M2 has more mass than M1 and M1 has more mass than M3. The questions refer to the magnitudes of tensions and weights. There is friction between the horizontal plane and M2 (μk ≠ 0). M2 is observed to travel at a constant speed. Assume that the pulleys are...

The correct answers are actually 1) True 2) False (It must exceed ukN not just uks) 3) True 4) True 5) False 6) False
