g Consider two parallel wires placed a distance of (12.5 A) cm apart. The current in the first wire is (4.50 B) A and the current in the second wire is (1.25 C) A. Determine the magnitude of the force per length exerted by the first wire on the second wire. Calculate the answer in Newtons per meter (N/m) and rounded to three significant figures.

What is the measure of how much matter is in an object and that can be measured using a balance? a. height b. volume c. weight d. mass

Two loudspeakers, 5.5 m apart and facing each other, play identical sounds of the same frequency. you stand halfway between them, where there is a maximum of sound intensity. moving from this point toward one of the speakers, you encounter a minimum of sound intensity when you have moved 0.33 m . assume the speed of sound is 340 m/s.part a) what is the frequency of the sound? part b) if the frequency is then increased while you remain 0.21 m from the center, what is the first frequency for which that location will be a maximum of sound intensity? express your answer to two significant figures and include the appropriate units.

Determine the net charge of the predominant form of arg at (a) ph 1.0, (b) ph 5.0, (c) ph 10.5, and (d) ph 13.5
