Make a conclusion on the relationship of mass to the rate of the change of motion of the balloon at a constant force.

sasho [114]

At a constant force, the mass of the balloon is inversely proportional to the rate of change motion of the balloon.

The force applied to an object can be determined by applying Newton's second law of motion, the force applied to an object is directly proportional to the product of mass and acceleration of the object.

F = ma

$F = m\frac{\Delta v}{t} \\\\\frac{F}{\frac{\Delta v}{t} } = m$

The mass of an object is inversely proportional to the rate of change motion of the object.

Thus, we can conclude that at constant force, the mass of the balloon is inversely proportional to the rate of change motion of the balloon.

The ____ of emitted light depends directly on the energy between the two orbits and this determines the color of the light

Anna007 [38]

The frequency of emitted light is directly proportional to the energy between the two orbits and this determines the color of the light.

<h3>What is light?</h3>

Light can be defined as a form of electromagnetic waves that does not require any medium for its propagation. This ultimately implies that, light is a form of wave that is generally referred to as a visual signal because it can be seen with the eyes.

According to the model of light wave, the frequency of emitted light is directly proportional to the energy between the two orbits and this determines the color of the light.

In conlcusion, the frequency of emitted light is highly dependent on the energy between the two (2) orbits.

You observe a star system for many weeks. The light curve does not show significant changes in brightness, but a series of spect

mariarad [96]

Based on the changes in the light curve and the behavior of the series of spectra, this is a binary system.

<h3>How is this is binary system?</h3>

The characteristics described are those of a binary system with the specific type of system being the spectroscopic binary system.

This is because in a spectroscopic binary system, there won't be significant changes in brightness but as a result of stars orbiting towards and then away from us, spectral features will appear as alternative absorption lines.

In conclusion, this is a binary system.
