    The possible effects on the water level

    When I was attempting this, I only factored in the mass staying the same and not the change in volume. Thank you so much for your help and making me realize my mistakes! I really appreciate it!

    The possible effects on the water level

    Does that means that it is hard to determine what will exactly happen to the level of the water? The water level might fall due to the smaller volume, which is related to the decrease in the radius. So it is hard to determine if the water level will fall or be unchanged.

    The possible effects on the water level

    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...

    Object Hanging in Railroad Car

    I have similar equations. I had an similar equation T=ma/mg, among a plethora of other equations (relevant or not). In these types of problems, my professor calls the horizontal acceleration the acceleration relative to the train. I know basic trig and basic trig functions. Vectors is an amount...

    Object Hanging in Railroad Car

    The equation was given to me by a classmate. It means that the force (acceleration) relative to the train divided by the force relative to the ground equals (the mass of the object times the force relative to the train) divided by (the mass of the object times the gravitational force). I have...

    Does F=tan(Fg/Ft)?

    Ft is the force relative to the train and Fg is the force relative to the ground.

    Object Hanging in Railroad Car

    I am not completely sure how to do the vector sum. Do I just add 9.81 and 1.3264?

    Object Hanging in Railroad Car

    How do I use the acceleration to find the tension in the rope? I tried using F=ma F=ma F=7.1* 1.3264 F= 9.4172 N This is not the correct answer. How do I find the tension from the acceleration?

    Object Hanging in Railroad Car

    Homework Statement A 7.1 kg object hangs at one end of a rope that is attached to a support on a railroad car. When the car accelerates to the right, the rope makes an angle of 7.7 degrees with the vertical, as shown in the figure below. What is the tension in the rope in Newtons? Homework...
