I just got %100 on my quiz, the answer is d(wind flow and temperature
The total distance traveled by the girl will be 40 meters and the displacement will be 30 meters.
Distance = total amount of path followed by any body called distance.
Displacement= The minimum distance between two points irrespective to the path followed by the body is displacement.
It is given that
Distance traveled to north direction = 10 metres
Distance traveled to south direction= 30 metres
So the path followed by the girl in total = North direction + south direction
= 10+30
= 40 meters
And the displacement = min distance between History class and fountain
= 30 meters
total distance traveled by the girl will be 40 meters and the displacement will be 30 meters.

The height of the apple from the ground can be calculated using the formula for gravitational potential energy. Given the apple's mass and its potential energy, we find that the apple is approximately 5000 meters from the ground.
The gravitational potential energy of an object can be calculated using the formula PE = mgh, where m is the mass of the object, g is the acceleration due to gravity (9.8 m/s² on Earth), and h is the height of the object from the ground. In this case, the apple's gravitational potential energy is given as 175J, its mass is 0.36g (or 0.00036 kg when converted.)
To find the apple's height from the ground, you need to rearrange the formula to solve for h: h = PE / (m * g). Substituting the given values in the formula, h = 175 J / (0.00036 kg * 9.8 m/s²), you get approximately h = 5000 meters.
