    Pressure Problem (math error I think)

    I don't know how to find the density at this depth. This is an intro physics problem, so are there any "assumptions" I can make?

    Pressure Problem (math error I think)

    Hi everyone, My question is as follows: Consider a point in the ocean about 9.60 km deep. The pressure at that point is huge, about 9.89 x 10^7 N/m^2. (a) Calculate the change in volume of 1.00 m^3 of water carried from the surface to this point in the ocean. I set up an equation...

    Calculating Tension of Rope for Scaffold with 690N Worker

    (I made a typo in my question, the scaffold is 690N and the person is 190N.) Regardless, I am not sure that I am completely understanding what you wrote. (1.45m)(-690N) + (T_1)(1.45m) = 0 (1.9m)(-190N) + (T_2)(1.0m) = 0 I have a feeling that is not right. Any more suggestions?

    Torque with Symbolic Notation Problem

    Hi Everyone, My question is as follows: Write the necessary equation of the object shown in Figure P8.4. Take the origin of the torque equation about an axis perpendicular to the page through the point O. (Let clockwise torque be positive and let forces to the right and up be positive. Use...

    Calculating Tension of Rope for Scaffold with 690N Worker

    Hi everyone, My question is as follows: A window washer is standing on a scaffold supported by a vertical rope at each end. The scaffold weighs 190N and is 2.9m long. What is the tension in each rope when the 690N worker stands 1.9m from one end? I know the sum of the forces has to...

    Pendulum problem in KE chapter

    [FONT="Comic Sans MS"]Hi Everyone, My question is as follows: A bullet of mass m and speed v passes completely through a pendulum bob of mass M. The bullet emerges with a speed v/2. The pendulum bob is suspended by a stiff rod of length and negligible mass. What is the minimum value of v...
