An 80-cm uniform 10-kg bar is resting on two scales, one at either end. a smaller 4-kg mass (m) is placed at a distance of d = 20 cm from the left end. because the mass is closer to the left scale, it reads a higher weight than the right scale. what is the difference between the weights read by the two scales (left scale minus right scale)?

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.

The place where two plates come together is known as a a. transform boundary. b. divergent boundary. c. convergent boundary. d. rift valley.
