    Tilt of Earth's Equator: Arctic, Antarctic, Tropics

    Homework Statement Suppose the tilt of Earth’s equator relative to its orbit were 177.4◦ (like Venus) instead of 23.5◦. At what latitudes would the Arctic and Antarctic Circles and the two Tropics be lo- cated? Homework Equations N/A The Attempt at a Solution I would like...

    Quantum Spin up spin down with magnetic field

    There is an external magnetic field along the positive z direction B = (0,0, B) and the initial spin direction at time t0= 0 is specified by the direction cosines Ŝ0= (cos α0, cos β0, cos γ0) where α0, β0, γ0 are the angles between the initial spin and the x, y, z axes, respectively. This...

    Linear acceleration of a rod fixed to a hinge at one end

    Theres a L and a r because the equation for alpha is a/r and the inertia equation is 1/3 m L2. Or am I approaching that wrong?ps thank you for helping me :)

    Linear acceleration of a rod fixed to a hinge at one end

    Homework Statement a uniform stick with a mass of 1.00 kg and length of 1.00m has a fixed hinge at one end. It is released at an angel of 60 degrees above the horizontal and it drops with normal gravity. What is the magnitude of the linear acceleration of the point at the free end just after...
