An ideal pendulum is often discussed when studying simple harmonic motion.

what are the conditions needed for an ideal pendulum? check all that apply.
a) gravitational force acts to pull the pendulum’s mass down.
b) the mass of the rod of the pendulum is evenly distributed along the rod.
c) the pivot on which the pendulum swings is frictionless.
d) the pendulum swings through its equilibrium position as a result of inertia.
e) tension acts downward on the pendulum’s mass.

Two technicians are discussing a resistance measurement between the can-h and can-l wires. technician a says this measurement should be done with the ignition switch in the "run" position. technician b states that a measurement of 0 ohms indicates an open in the network. which technician is correct?

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
