A train of waves is moving at a speed of 30 meters per second. The frequency of the wave is 10 Hertz. What is the wavelength?

what question you dont ask a question

explanation:

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
