When a wave transfers from one medium to another with different properties, the speed of the wave can change. In this case, we know that the wavelength changes when the wave transfers from the first type of rope to the second type of rope. If the wavelength becomes one-fourth of what it was before the transfer, this means that the second type of rope has a higher wave speed than the first type of rope.
The wave speed is defined as the product of the wavelength and the frequency of the wave. Since the frequency of the wave remains constant as it transfers from one medium to another, a decrease in wavelength means an increase in wave speed. This can be seen from the wave equation, c = λf, where c is the wave speed, λ is the wavelength, and f is the frequency.
Therefore, if the wavelength becomes one-fourth of what it was before the transfer, this means that the wave speed in the second type of rope is four times the wave speed in the first type of rope. In other words, the speed of the wave becomes quadruple its original speed after the transfer.

Answer:
the answer is pounds
Explanation:
In everyday speech, the phrases "mass" and "weight" are frequently used interchangeably, yet they have different meanings. Weight is a measurement of how the force of gravity works upon a mass, whereas mass is a measure of the amount of matter in a material. Therefore, Weight and mass are not interchangeable terms.
A body's mass is an inherent quality. Prior to the discovery of the atom and particle physics, it was widely considered to be tied to the amount of matter in a physical body.
The quantity of matter in an item is its mass. The gravitational pull exerted on a mass is known as weight. Combining the two would be confusing because workplace can affect weight.
An object's mass is a crucial indicator of how much stuff it contains. Weight is a measurement of an object's gravitational pull. It is influenced by the object's location in addition to its mass. As a result, weight is a measurement of force.
Thus, Weight and mass are not interchangeable terms.

Volume % = mole %
Molar mass of oxygen = 32kg/kmol
Molar mass of nitrogen = 28 kg/kmol
Density of nitrogen = Density of oxygen x molar mass of oxygen x molar ratio of air x molar mass of nitrogen
Density of nitrogen = (1.43kgm^-3)(1 kmol O2/32 kg O2)(80 kmol N2/ 20 kmol O2)(28 kg N2/1 kmol O2) = 5.01 kg/m3
