Since the formula for the circumference of a circle is pi x d or pi x 2r. The radius is a straight line from the center of the circle to the outer part of it, which is exactly what the spokes are to the wheel. So we take the length of the spoke, which is the radius, and use it in our equation. pi times 2 times the length of the spoke will give us our answer.

Which states of a hydrogen atom can be excited by a collision with an electron with kinetic energy k = 12. 5 ev?
Sophie [7]

The answer is the  excited state of the hydrogen atom, n=24 and Z=23

Kinetic energy of electron is, $\mathrm{KE}=\frac{13.6 \mathrm{Z}^{2}}{\mathrm{n}^{2}} \mathrm{eV}$

For  the  excited state of the hydrogen atom , n=24 and Z=23

K.E=\frac{13.6 \times 23^{2}}{24^{2}}=12.5

What is the hydrogen atom?

  • The hydrogen atom is the most basic of all the atoms since it just has one proton and one electron.
  • There are two more hydrogen isotopes, deuterium and tritium, in addition to protium, which is the most prevalent form of the atom.
  • The hydrogen atom consists of a proton and an electron, and has a spherical symmetry that can most easily be studied using a spherical polar coordinate frame.

What part of an electric circuit are the wires that carry the electric current
bezimeni [28]

Answer:

okay so, An electric circuit is a closed loop through which current can  actually flow. All electric circuits must have a voltage source, for example a battery, and a conductor, which is usually  a wire.

how does it flow or how does .current flow in a circuit ? When a wire is connected to battery terminals which is electrons, electrons flow from negative to positive. Electrons have a negative charge in case you didnt know. they are repelled from the negative and attracted to the positive.

if this helped please mark this as brainliest!!! :)
