Assume the elevator is moving upward at increasing speed. Rank the magnitude of the forces. Rank from largest to smallest. To rank items as equivalent, overlap them.
1. the force of the 3kg block on the 2kg block, F3on2
2. the force of the 2kg block on the 3kg block, F2on3
3. the force of the 3kg block on the 1kg block, F3on1
4. the force of the 1kg block on the 3kg block, F1on3
5. the force of the 2kg block on the 1kg block, F2on1
6. the force of the 1kg block on the 2kg block, F1on2
7. force of the 1kg block on the floor, F1onfloor
8. force of the floor on the 1kg block, Fflooron1

electric field is a function of 1/r^2

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

a. carbon monoxide from car exhaust

b.particulate matter, such as soot

c.water vapor from a factory smokestack

d.acid rain

these are the answer choices im on that question right now

the correct answer is "inertia"

chemical energy --> gravitational potential energy --> kinetic energy --> elastic potential energy --> gravitational potential energy

explanation:

when emma starts the hike, the chemical energy stored in her body is used to climb up the mountain, and so she gains gravitational potential energy (because at the end, she will be at a higher height h above the ground). then she goes bungee jumping: as she falls, this gravitational potential energy is converted into kinetic energy (because her speed increases as she falls down), until the point when the rope stretches, and she stops moving. at that moment, all the kinetic energy is converted into elastic potential energy due to the stretching of the rope. then, this energy is released because the rope returns to its natural length, and emma gains a small increase in altitude , so she gains some gravitational potential energy.
