A 12 g bead is strung on a long, straight wire. It is accelerated, with no friction, by a force that acts at an angle to the wire. If the force has a constant value of 0.15N and acts over a distance of 75 cm and if the bead's final speed is 3.0 m/s and it starts at 1.0m/s, what is the angle between the force and the wire? Be sure to convert to MKS units (meters, kilograms, seconds).F

The position of a crate sliding down a ramp is given by x=(0.05t^3) m, y=(1.7t^2) m, z=(6−0.85t^5/2) m, where t is in seconds. (a) determine the magnitude of the crate's velocity when t = 2 s. (b) determine the magnitude of the crate's acceleration when t = 2 s.

In the circuit shown below, with each bulb holding a resistance of 60 ohms, how many amps of current are flowing? express your number as a decimal.

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?
