The potential energy of an object attached to a spring is 2.60 J at a location where the kinetic energy is 1.40 J. If the amplitude of the simple harmonic motion is 16.0 cm, calculate the spring constant and the magnitude of the largest force spring, max that the object experiences.

= Nm

spring, max= N

What is the earliest point in the universe that we can observe? why can’t we see back further than this?

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?

Since the energy was not raising the temperature of the water during these segments, what was the energy used to do instead? your answer must include an explanation of what is happening to the molecules.
