Every 10.0 seconds, a crest of the wave passes the pier. This means that the period of the wave is exactly 10.0 s:

which means that the frequency of the wave is

The wavelength of a wave is related to its frequency by the relationship

where v is the speed of the wave.
In this problem, v=5.6 m/s; if we use the previous formula, we find the wavelength of the wave:
Conductor because it creates heat.
The average rate of change of distance over the time interval
3 ≤ t ≤ 6 represents the coin's average velocity over that interval.
Suppose car A is moving with a velocity Va, and car b with a velocity Vb,
According the principle of conservation of momentum:
Va x Ma + Vb x Mb = (Ma + Mb) V
V = (Va x Ma + Vb x Mb)/(Ma +Mb)
V = speed of cars after coupling
V = (Va x 20 mg + Vb x 15 mg)/(20 mg + 15 mg)
Put in the values of Va and Vb, and get the V
Answer:
Explanation:
The fundamental charge of a single electron is
.
If there are 10 excess electrons, the net charge that would be measured should be 10 times the fundamental charge of a single electron:
