Let's choose east as positive x-direction and south as positive y-direction. We can resolve the two displacement along these two axes:
- Displacement 1 (3.5 km,
south of west


- Displacement 2 (2.7 km,
east of south


So, the total components on the two directions are


And the magnitude of the hiker's resultant displacement is

Explanation:
The five basic postulate of kinetic molecular theory includes:
1) All gases consist of large amount and numbers of tiny particles that are far apart from each other and also relative to their size.
2) The collisions between gas particles and gas particles against container walls is refer to as elastic collision.
3) All gas particles are in a continuous random and rapid motion. They possess kinetic energy which is energy of motion.
4) There are no attractive force between gas particles.
5) The temperature of a gas depends on the average kinetic energy of the gas particle.
False it refers to frequency
Answer: A) O N
Explanation:
An object in motion will maintain its state of motion. The presence of an unbalanced force changes the velocity of the object.
