Aparachutist's fall to earth is determined by two opposing forces. a gravitational force of 605 n acts on the parachutist. after 3 s, she opens her parachute and experiences an air resistance of 689 n. at what speed (in m/s) is the parachutist falling after 10 s?

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 j 1: write the equation2: list out your known variables 3: plug the numbers into the equations 4: solve 5: write your solution statement that includes initial energy and final energy added you so much!

What is friction? how does it affect the motion of an object?

Students in an introductory physics lab are performing an experiment with a parallel-plate capacitor made of two circular aluminum plates, each 11 cm in diameter, separated by 1.0 cm. how much charge can be added to each of the plates before a spark jumps between the two plates? for such flat electrodes, assume that value of 3×106n/c of the field causes a spark.
