<em>Hydrogen bond is the attractive force between the hydrogen attached electronegative atom </em>
Explanation:
The butterfly takes a vertical perpendicular path equivalent to 9m and travels a horizontal distance of 17m. The net path between the two is equivalent to that of the hypotenuse, so we will apply the Pythagorean theorem.


Therefore the magnitude of the butterfly's displacement is 9m
It is either 98 J or 98 N let me check..
725 Kg equals 725x9.8= 7105 N
