Answer:
The wavelength is about 733 meters.
Explanation:
Use the wavelength-frequency relationship:
The wavelength is about 733 meters.
The correct answer is
C. The battery
The battery is a device that provides a potential difference in the circuit, and so an electromotive force (e.m.f.) which pushes the electrons in the circuit from the negative pole towards the positive pole of the battery, so they move through the circuit. Therefore, it provides electrical energy.
225 = 1/2 (50) (v2)
225 = 25 (v2)
225/25 = v2
9 = v2
√9 = v
v = 3 m/s
GPE= height x mass x gravitational field strength
5 x 10 x 9,8=490J
Answer:
-8m/s
Explanation:
v=wavelength*f=-2*4=-8m/s
