We have that for the Question, it can be said that the maximum velocity is
From the question we are told
A 2.00kg block is attached to a horizontal ideal spring with a <em>spring</em> constant k=100Nm.
The block-spring system is set on a <em>horizontal </em>surface with negligible friction.
Generally the equation for the Potential energy is mathematically given as
The PE is converted to KE, Therefore

Complete Question
A 2.00 kg block is attached to a horizontal ideal spring with a spring constant k = 100 N The block-spring system is set on a horizontal surface with negligible friction. A graph of the potential energy U as a function of time t for this system is shown. The maximum displacement IMAX of the block from its equilibrium position and the maximum speed Umat of the block during the motion represented by the graph are most nearly A IMAX = 2.0 m and UMAX 1.4" B UMAX = 1.4 and UMAX=0.20" с MAX 0.20 m and UMAX = 1.4" D IMAX 0.40 m and UMAX 1.4 E IMAX 0.04 m and UMAX 2.0"
Answer:
From the highest to the lowest
Third excited state (n=4) Second excited state (n=3) First excited state (n=2) Ground state (n=1)
Explanation:
The Bohr Model, by Niels Bohr, is a planetary model in which the negatively charged electrons orbit a small, positively charged nucleus similar to the planets orbiting the sun. Niels Bohr in his model states that:
- The electron is able to revolve in certain stable orbits around the nucleus without radiating any energy
- Electrons can only gain and lose energy by jumping from one allowed orbit to another, absorbing or emitting electromagnetic radiation with a frequency ν determined by the energy difference of the levels according to the Planck relation: = hv, where h = planck's constant.
The lowest value of n is 1, which is the ground state
n = principal quantum number
Therefore, from the highest to the lowest, the energy levels are ranked as:
Third excited state (n=4)
Second excited state (n=3)
First excited state (n=2)
Ground state (n=1)
Answer:
they share electrons between them.

taking the test rn lol i think its right
Answer:
Organic matter decomposition serves two functions for the microorganisms, providing energy for growth and suppling carbon for the formation of new cells. ... Dead plant residues and plant nutrients become food for the microbes in the soil

Answer:
Periods indicate that a new period at a new principal energy level which is filled with electrons. Groups indicate that the elements share similar properties because their shells are filled with the same number of valence electons.
Explanation:
e see that starting at period 2 Li has a +1 charge , He has +2 charge, B has +3 charge, C has the potential to have a +4 charge or -4 charge (because it can gain or loose electrons) and N has a -3 charge, etc. Groups however, have similar properties and every element in a 1A - 8A has the same number of valence electrons. All except the noble gases in which He only needs 2 electrons to be in a perfect state. This is its octet as it would be a completely different element if it had more than 2 electrons in its shell. An example of the groups sharing similar properties is if we were to look at group 1A. In group 1A we find H, Na, K, etc. These are all highly unstable elements when alone (not in a compound) and they are very reactive. If you were to put Na for instance in water, it would light up and you'd see a flame sitting on top of the water. A scientist could do that with the rest of the elements in the group and they would see this increasing in reactivity as you go down the periods. Francium isn't visible long enough to be able to see this happen though. It's more of that kind of element that scientists prove that it exists, but not a very common element to get to learn much about.
