We can see it as two movements: one on the north-south axis and one on the west-east axis.
On the north-south Axis, the hiker went 8 km north and 4 km south, so in total the hiker went 4 km north (we can subtract one for the other and the direction remains that which was bigger)
On the west-easth Axis, the hiker went 6 km east and 6 km west, so in total the hiker didn't move on this axis! or, he/she moved but then "came back"
So in total, the hiker only moved4 km north - answer B.

Needs mass to be reasonably solvable, sorry

The answer is zero.
A simple harmonic motion has zero total mechanical energy as it moves beyond the equilibrium point, when it achieves the maximum displacement, when it moves past the equilibrium point, and when it moves past the equilibrium point and a non-zero constant.
What is simple harmonic motion?
- Simple Harmonic Motion (SHM) is a periodic, to and fro shifting rotation about the mean position of the body. The restoring force on an oscillating body is geared toward its mean direction since it is exactly proportional to its displacement.
- The sum of the potential energy and the kinetic energy constitutes the total energy in brainly.com/question/17315536.
- The particle's total mechanical energy when performing simple harmonic motion.
- The sum of the kinetic energy of the block plus the potential energy stored in the spring, which is proportional to the square of the amplitude, makes up the total energy of the block and spring system.

I dont know what the statements are but concave lens are thinner in the middle which cause light to diverge or scatter
