Answer:
true b and c
Explanation:
n the electromechanical transitions of the atoms the relationship must be fulfilled
= R (1 / nf - 1 / no²)
where for the final state nf = 1 giving in the case of hydrogen the Lymma series whose smallest wavelength is lam = 122 nm with nf = 1 and there are a series of spectral lines for each value of n of the final state
in the case of sodium so well it has a transition from an excited state to the kiss state (bad)
Now let's review the different proposals
a) False. The electronic potential for sodium is much lower than for hydrognosia
b) True
c) True
d) true
Lol, I remember I helped my sister with this question but anyways, the card flew because of inertia and the quarter fell in the glass because of gravity :).
The sum of all forces on an object is the net force or resultant force. If all the forces cancel out , resultant force is zero , otherwise unbalanced force will cause acceleration of object .
Force is the vector, has both direction and magnitude.
This can be explain through Newton’s first law of motion where an
object at rest remain in rest unless acted upon by an unbalanced force. Hence,
the dust particles having inertia and trapped within the pores of the carpet
has the tendency to remain at the state of rest, it does not move and resist
motion but when the carpet is beaten with a stick, dust comes out because the
force from a stick acted upon it.
