I'm gonna have to assume the girl is on the right side and boy on left.
The net force is the sum of all forces on an object (includes negatives).
Let's say the force of the boy is variable <em>b</em>. Use the formula F = ma.
<em>b </em>+ 3.5 = 0.2(2.5)
This is now simple algebra. Solve to get that <em />the boty is exerting a force of -3N to the left.
There are 5 dwarf plabets
Answer:
P = 760 torr
Explanation:
Significant figures give information on the pressure of a measurement, and is directly related to the appreciations of the instruments.
When we make several different measures, some have more significant figures than others, but the criterion that ae uses is that we must use it to have the least number of significant figures, since here is the error
In this case we have 3 significant figures so the pressure value must be
P= 759.5 torr = 760 torr
Notice that we have rounded the nine (9) since the following figure is greater than or equal to 5
