a. 3.3 × 10-8 coulombs

b. 3.6 × 10-6 coulombs

c. 4.8 × 10-8 coulombs

d. 6.0 × 10-8 coulombs

e. 3.3 × 10-3 coulombs

What type of nuclear decay causes the atomic number of an element to increase by 1?

The two required components for a generator

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.
