A chemical property is a change in classification in matter I think
Answer:
makes a transition from a high to a lower energy state
Explanation:
The emission spectrum is the spectrum of electromagnetic radiation emitted due to the transition from a state of high energy to a state of lower energy made by an electron in the atoms of the chemical element or compound. The emitted photons have an energy equal to the difference in energy between the two states.
Can't find the options on the keyboard so ill try to describe it. I think either an He symbol or the greek letter alpha is accepted. There must be a 4 at the top left and a 2 at bottom left.
Answer:
Explanation:
By using the Newton second law and the position equation for a simple harmonic motion we have

where a is the acceleration, w is the angular frecuency and \phi is the phase constant. We can calculate w from the equation for the maximum acceleration

(a).

(b). 
(c). 
(d). The mecanical energy is the kinetic energy when the velocity is a maximum
