Explanation:

This is because the other variables in the other choices are relative to different observers and hence are not good to use in an experiment because there will be a lot of inherent bias by the person conducting the experiment For example how one person views how strong or beautiful the maple or oak looks may be different from how another person perceives the same.

However, weight is an absolute SI unit and does not vary from experiment to experiment. It is, therefore, a non-biased variable to use in the experiment and determine which wood between oak and maple can hold more weight.

If frequency is kept constant, how are the velocity and wavelength of a wave related?

Elan Coil [88]

<h3>Answer;</h3>

Velocity and wavelength are directly proportional when frequency is kept constant.

<h3>Explanation;</h3>

Frequency of a wave is the number of complete oscillations made by a given wave in one second.
Wavelength on the other hand, is the distance between two successful crests or troughs in a transverse wave or two successful rarefactions or compressions in a longitudinal waves.
The speed of a wave is given by the product of the frequency of a wave and the wavelength.
Speed = Frequency × wavelength, 
Therefore, if frequency is kept constant, then the speed of a wave is directly proportional to the wavelength, such that an increase in wavelength increases the speed of the wave and vice versa.

Both retinal disparity and convergence increase as an object gets closer to the individual.

Gnom [1K]

That statement is true

Retinal disparity : space between your eyes that allow binocular vision to create depth perception

Retinal Convergence : Space between your eyes that signal visual moves to the retina

They both will increases as an object get closer to the individual, allowing them acknowledge and observe the existence of the object
