Hi pupil Here's your answer ::

When we walk on the ground, our foot pushes the ground in the backward direction(action), on the other hand, ground wishes our foot in the forward Direction(reaction). This reaction of ground helps us to move in the forward direction. But when our foot falls on the peel of Banana, then our foot slips on a peel of banana and cannot push the ground in the backward direction so, no reaction force acts on a body. Hence, we lose the balance and fall down.

Answer:
1. √74; 2. (24.5, 21.5)
Step-by-step explanation:
1. Distance
You could use the distance formula to calculate the length of PQ, but I prefer a visual approach, because it requires less memorization.
Draw a horizontal line from P and a vertical line from Q until they intersect at R (28, 19).
Then you have a right triangle PQR, and you can use Pythagoras' theorem to calculate PQ.
2. Midpoint of line
The coordinates of the midpoint are half-way between the x- and y-coordinates of the end points.
For the x-coordinate, the half-way point is
(21 + 28)/2 = 49/2 = 24.5
For the y-coordinate, the half-way point is
(19 +24)/2 = 43/2 = 21.5
The coordinates of the midpoint M are (24.5, 21.5).
