Frequency is the number of wave passing through a certain point per unit time. The frequency of the given wave is 6.5 Hz.

Frequency:

It is the rate of wave oscillation per unit time. It is measure in Hertz. One Hertz is equals to a wave passing from a point in 1 second.

Frequency of the wave can be calculate by the formula,

$\bold {V = f\lambda }$

Where,

V - speed of the wave = 65 m/s

f - Frequency = ?

$\bold {\lambda }$ - wavelength = 10 m

put the values in the formula and calculate it for f,

$\bold {65 = 10\times f}\\\\\bold {f = \dfrac {65}{10}}\\\\\bold {f = 6.5 Hz}$

Therefore. the frequency of the given wave is 6.5 Hz.

f = 6.5Hz

Explanation:

Given that the

Speed V = 65 m/s

Wavelength (λ) = 10m

Wave speed is the product of frequency and wavelength. That is,

V = fλ

Substitute V and (λ) into the formula to get frequency f

65 = 10f

Make f the subject of formula

f = 65/10

f = 6.5 Hz

Therefore, the frequency of this wave is 6.5 Hz?

most voltage drop calculators want the distance between the source and destination. then internally, they double it so both the source and return wires are calculated. but you need to know which distance the calculator uses so you're not half of what you should be or double what you should be.

most circuit breakers will not take a #6 directly, so the electrician will have to splice on a smaller pigtail. you also have to upsize the grounding wire when you upsized the ungrounded (hot) wire (see note in 250.122). this will preclude using most cable assemblies, as a cable with #6 copper will most likely only have a #10 grounding conductor. you need a #6 grounding conductor if the circuit is 20a. a #8 cable is no better, as it will have a #10 grounding conductor too. but most 20a breakers will take a #8 directly.

in your related post, you didn't say what type of load this is. if it is a light or heater, voltage drop won't be a big issue. if this is a motor, the current needs are huge at startup and the voltage drop can pose a problem. if this is a motor, knowing if the motor is under much load during startup will answer the voltage drop effect (a saw is easier to start than a compressor).

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).
