The best translation of the following sentence "as for me, i don't know" we have that will be "por mi parte, no sé".
This will be the correct translation because when we look at the translation of the other options we have that they correspond to :
- "para siempre, no sé" wil correspond to "forever i don't know"
- "para que sepas, no sé" will correspond to "just so you know, i don't know"
- "por ejemplo, no sé" will correspond to "for example, I don't know."
In this way, the translation that best suits is "por mi parte, no sé".

The net force on the bookcase in the direction of its motion is
∑ F = 65 N - F[friction] = (41 kg) (0.12 m/s²)
so that friction has a magnitude of
F[friction] = 65 N - (41 kg) (0.12 m/s²) = 60.08 N
The net force on the bookcase perpendicular to the surface is
∑ F = F[normal] - (41 kg) g = 0
so that
F[normal] = (41 kg) g = 401.8 N
If µ is the coefficient of kinetic friction, then
F[friction] = µ F[normal]
so that
µ = F[friction] / F[normal] = (60.08 N) / (401.8 N) ≈ 0.15

The gas with a higher pressure is <u>Helium </u>
<h3 /><h3>Calculating the pressure exerted by the gases</h3>
Given that temperature and volume is held constant the pressure of a given gas can be calculated as : P = n because for a constant volume and temperature the pressure of a given gas is directly proportional to the number of moles of contained in the gas.
<u>Pressure of </u><u>Helium </u>
P = n
where n ( number of moles ) = mass of helium / molar mass
= 52 / 4 = 13 moles
<u>Pressure of</u><u> Ammonia </u>
P = n
where n ( number of moles ) = mass / molar mass of ammonia
= 73 / 17.03
= 4.29 moles
From the calculations above the gas with a higher pressure is Helium.
