How much work is needed to push a 117- kg packing crate a distance of 2.75 m up an inclined plane that makes an angle of 28 o wi

Nataly_w [17]

Answer:

$W_{tot,min} = 1481.372\,J$

Explanation:

The minimum total work is the work needed to counteract the work associated with the weight:

$W_{tot, min} = W_{F}$

$W_{tot,min} = m\cdot g\cdot \sin \theta \cdot \Delta s$

$W_{tot,min} = (117\,kg)\cdot (9.807\,\frac{m}{s^{2}} )\cdot (\sin 28^{\textdegree}) \cdot (2.75\,m)$

$W_{tot,min} = 1481.372\,J$

Why are there two fluoride ions in magnesium fluoride but only one fluoride ion in lithium fluoride

postnew [5]

This would be more of a chemistry question. Remember magnesium has a charge of 2+, and would need to hand off its two extra electrons. Fluorine can only take one electron at a time, so there needs to be two fluorines to take one magnesium's 2 electrons.

With lithium, it has a +1 charge, so it has one extra electron, which it can hand off to just 1 fluorine atom.

Another way of looking at this is: $Mg^{2+}$ + 2 $F^{-}$ = MgF2 (the charges must balance out to zero)

$Li^{+}$ + $F^{-}$ = LiF (the charges balance out to zero)
