Jerry drove to a park to take a four-day hike. He parked his car at the beginning of the trail, and then walked: 5 kilometers north on day one, 3 kilometers south on day two, 8 kilometers east on day three, and 2 kilometers west on day four. What is Jerry’s final position, relative to his parked car? A. 2 kilometers north and 6 kilometers east from the car B. 2 kilometers south and 6 kilometers west from the car C. 8 kilometers north and 10 kilometers east from the car D. 8 kilometers south and 10 kilometers west from the car

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.

i need with 1.3.2 investigate cycling o2 and co2 apex

we need to see it
