Answer:

Scenario B)

Explanation:

The elastic potential energy stored in a spring is given by:

U=\frac{1}{2}kx^2

where k is the spring constant and x is the compression/stretching of the spring.

Let's calculate the potential energy of each spring by using this formula:

A) U=\frac{1}{2}(3 N/m)(1.0 m)^2=1.5 J

B) U=\frac{1}{2}(6 N/m)(0.8 m)^2=1.92 J

C) U=\frac{1}{2}(9 N/m)(0.6 m)^2=1.62 J

D)  U=\frac{1}{2}(12 N/m)(0.4 m)^2=0.96 J

Therefore, the scenario with most elastic potential energy is B.

An iron atom (Fe) has 26 protons in it. If the atom has 20 electrons in it, explain what type of charge it has and how you can t
gogolik [260]

Answer:

The iron atom has a positive charge, making it a cation.

Explanation:

The atom has a nucleus, where the protons and neutrons, which are the subatomic particles with the highest mass, are located. Practically all the mass of the atom is concentrated in the nucleus.Protons have a positive electrical charge, while neutrons have no charge.

Electrons move around the nucleus with other negatively charged particles.

An iron atom (Fe) has 26 protons and 20 electrons in it.  That is, there are 6 more protons than electrons. As mentioned, protons are positively charged. So <u><em>the iron atom has a positive charge, making it a cation</em></u>.

Which property of light would provide evidence for the idea that light is a wave?
Lena [83]

Color property of light would provide evidence for the idea that light is a wave

<h3><u>Explanation:</u></h3>

The reality is that light manifests practices that are representative of both waves and particles. Young proposed that light of varying colors was formed of waves possessing various lengths, a basic theory that is popularly believed today. In contradiction, the particle theory advocates envisioned that several colors were obtained from particles holding either various masses or moving at various speeds.

All waves are perceived to experience refraction when they transpire from one means to another means. Light, similar to any wave, is apprehended to refract as it transfers from one medium into another medium.
