There are two possible answers:
<span>- it can move out to a higher electron shell
- </span><span> it can stay in its original shell
</span><span>
In fact, sunlight consists of photons. When sunlight hits an electron, the electron can absorbs a photon, so it gains energy: as a result, the electron can move to a higher electron shell, which corresponds to a high energy level in the atom, if the energy given by the photon is at least equal to the energy difference between the two levels. However, if the photon energy is not large enough, the electron will stay in the same shell.</span>
Answer:
4.88 K.
Explanation:
From the question given above, the following data were obtained:
Number of mole (n) = 5 moles
Pressure (P) = 1 atm
Volume (V) = 2 L
Gas constant (R) = 0.082 atm.L/Kmol
Temperature (T) =?
The temperature of the gas can be obtained by using the ideal gas equation as illustrated below:
PV = nRT
1 × 2 = 5 × 0.082 × T
2 = 0.41 × T
Divide both side by 0.41
T = 2 / 0.41
T = 4.88 K
Therefore, the temperature of the gas is 4.88 K.
Answer:
acceleration of the particle as a function of time is given as
and position of the particle as a function of time is given as
Explanation:
we have given,
at t=0, s=0
therefore initial velocity,u
u=v=
v=u+at.........(1)
we know from first equation of motion
let acceleration at time t be a(t), and position be x(t)
put value of v,u and a in equation 1
we got,
Therefore,acceleration of the particle as a function of time is given as
and position of the particle as a function of time is given as
Answer:
Explanation:
Coordinate system is one that describe the location of an object in a given plane. It implies the use of axes (coordinates) and points.
Given that the man in the question walks 400 m due north of east. The cardinal points can be used in this case, with the north and east cardinals as the required axis.
scale =
=
=
scale = 1:40
This is a reduced scale which implies that 1 cm on the drawing is equal to 40 m on the original length.
The man's direction is north of east.
The graphical drawing of the vector is herewith attached to this answer.
