Apendulum is rigidly fixed to an axle held by two supports so that it can swing only in a plane perpendicular to the axle. the pendulum consists of a mass m attached to a massless rod of length (. the supports are mounted on a platform which rotates with angular velocity ω. find the pendulums stable equilibrium position and frequency for small amplitude oscillations, when ω is constant.

To run the physics cart, the fan speed of the cart is manipulated. this is the (blank) variable. the cart accelerates due to the speed of the fan. acceleration is therefore the (blank) variable. a “constant” is a parameter that stays the same regardless of the variables. one parameter of the cart that is held constant is the (blank) .

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
