Answer:
Action and Reaction
Explanation:
For every force, there is one of equal and opposite also. Think of it this way. When you try to push on a wall, you are applying a force. However, that wall is also pushing back on you with that same force. You can also see this when you high five someone. You can slap as hard as you want to their stationary hand, but due to the 3rd law, you're both going to be left with red hands do to the amount of force applied.
Its like the weather man. They are the people you see on the news that use radars ect. To predict the weather.

White light (containing all visible colors) passes through a gas that absorbs some of the light, the spectrum is then analyzed.
That spectrum best be described as a spectrum that is continuous except for few black lines.
<h3>What is spectrum?</h3>
- The variation in light's intensity with frequency or wavelength.
- A spectroscope is a device created for visual spectral observation, while a spectrograph is a device that captures or maps spectra.
- The sun's spectrum of colors, the rainbow, and a molecule's infrared absorption wavelengths are a few examples of spectra.
- Continuous, emission, and absorption spectra are the many types.
- A conceptual tool called the Spectrum is used to map and organize the electromagnetic wave's physical events.
- The electromagnetic spectrum is the collection of all conceivable radio frequencies at which these waves can flow through space.

having to push a rough and heavy box across the floor to move it
Explanation:
Friction is not a useful force because we have to exert even more force to push a body that is rough and heavy across the floor to move it.
- Frictional force is a force that opposes the motion of a body.
- It costs more and uses more energy to push a rough and heavy box on surface because of friction.
- This wastes energy in systems that deals with pushing.
Friction is useful in that:
- the heat energy produced when two surfaces rub together is very useful.
- the friction between your feet and the floor keeping you from slipping and makes walking possible.
- the tread on tires helping the moving vehicle slow down and stop when necessary.
