In order to get the propoerty of work you need to use the following formula
<span>work = force times distance
</span>replacing data you will get:
W = (1.500) (3)
W = 4.500 NM
The answer should be in NM. So it will be 4500 NM againts the force of gravity
Let and be the vectors, and let be their common magnitude.
The resultant is times larger in magnitude than either vector alone, so .
Recall the dot product identity
where is the angle between the vectors and . In the special case of , we get
Now, to get the angle between and , we have
To compute the dot product, we take the dot product of the resultant with itself.
Solve for .
Since their dot product is zero, and are perpendicular, so .
B.
ice cubes melt and cause water to dilute the soda but it makes the soda colder. the soda is now colder because the ice cubes melted.
