Consider a wave generator that produces 10 pulses per second. The speed of the waves is 300. cm/s.
a. What is the wavelength of the waves?

b. What happens to the wavelength if the frequency of pulses is increased?

0.3

Explanation:

speed is 3m/s, and in 1 second there are 10 pulses. This means that to get 3m/s, you must multiply something by 10.

3=10x

0.3=x

Wave speed = (frequency) x (wavelength)

3 m/s = (10 / sec) x (wavelength)

Divide each side by (10/s) :

Wavelength = (3 m/s) / (10 / s)

Wavelength = 0.3 meter

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
