4. Four forces act on a plywood hexagon as shown in the diagram. The sides of
the hexagon each have a length of 1 meter.

Rank the magnitude of the torque applied about the center of the hexagon by
each force.

Apulley with a mechanical advantage of 5 will require you to pull times the amount of rope. a. 1/5 b. 5 c. 10 d. 15

Is there a point between a 10 nc charge and a 20 nc charge at which the electric field is zero?

Anonzero net force acts on a particle and does work. which one of the following statements is true? the kinetic energy of the particle changes, but the speed of the particle does not change. the kinetic energy of the particle does not change, but the speed of the particle does change. the kinetic energy of the particle changes, but the velocity of the particle does not change. the kinetic energy and the speed of the particle change, but the velocity of the particle does not change. the kinetic energy, speed, and velocity of the particle change.
