Two carts pushed by fans were set in motion at the same time and let run for 27.0 seconds. The results of which are shown on the right along with the relative strengths of their fan units. The speed arrows are the same length. a. At 27 sec mark, how do the speeds of the two carts compare?

b. Given your answer in part a. and the forces of the two fans shown, how do the masses of the two carts compare

c. Given your answer in part b. suggest a possible mass for each cart including appropriate units for mass that would give the same simulation results as shown.

the word is fan force 10 and fan force 35 not just force

You and a friend (alex) are at a a tree-top adventure park .. . part of the course requires you to climb up a rope. you both climb the same rope in the same amount of time. however, the tension in the rope is greater when alex climbs. who did the most work? alex did - more tension means more force - more force means more work was done you did - less tension means less force - less force means more work was done to find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? when more work was done, the couch was moved less. when more work was done, the couch was moved further. when more work was done, the couch wasn't moved at all. when more work was done, the couch was moved the same distance.

Determine the age of a fossil if it had only one eighth of its original carbon-14 content remaining?

If anyone who can me with this hw? i would really appreciate it
