3. A 6 kg, 2 meter long, uniform teeter totter is situated as shown below. The fulcrum is placed 30 cm to the left of the center of mass of the board. Calculate
the force, F, that the person at the end of the teeter totter must exert to place it in
rotational equilibrium. Note: when an object is not supported at its center of
mass, the weight of the object will cause torque

How does the kinetic energy of a charge change as the charge moves under the effect of an electric field from higher potential to lower potential? a. the kinetic energy increases. b.the kinetic energy decreases. c.the kinetic energy remains the same. d.the kinetic energy is always zero.

Atriangle with equal sides of length 10 cm has -2.5-nc charged objects at each corner. part a determine the direction of the electrical force exerted on the object at the top corner due to the two objects at the horizontal base of the triangle. determine the direction of the electrical force exerted on the object at the top corner due to the two objects at the horizontal base of the triangle. horizontally rightward vertically downward vertically upward horizontally leftward

Which describes increasing the efficiency of energy resource
