A 1710 N irregular beam is hanging horizontally by its ends from the ceiling by two vertical wires (A and B), each 1.30 m long and weighing 0.320 N. The center of gravity of this beam is one-third of the way along the beam from the end where wire A is attached. Ignore the effect of the weight of the wires on the tension in the wires. a.) If you pluck both strings at the same time at the beam, what is the time delay between the arrival of the two pulses at the ceiling?

Luke and carrie are driving down a straight section of the interstate at 70 mph in luke's new convertible. carrie is drinking a soda in the passenger seat. when she is done she tosses the bottle straight up in the air, just above the height of the car. what will happen to the bottle if air resistance is neglected? a. the bottle will land in carrie's lap. b. not enough information is given. c. the bottle will land on the interstate in front of the car. d. the bottle will land on the interstate behind the car.

What is the equation for electrical work?

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14πϵ0. d)the ball will oscillate along the z axis between z=d and z=−d in simple harmonic motion. what will be the angular frequency ω of these oscillations? use the approximation d≪a to simplify your calculation; that is, assume that d2+a2≈a2. express your answer in terms of given charges, dimensions, and constants
