What should be the main focus of a scientist's attention while reaching across a table to pick up a beaker?
O calculating how much liquid should be poured into the beaker
O considering how liquid in the beaker will react with another liquid
O wondering if experimental data is being collected correctly
O making sure that there is no other lab equipment in the way

Avalue that describes how heavy an object is and is related to the force of gravity is

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.

1. explain how you calculate the net force in any direction on the box. 2. suppose an upward force of 15n is added to the box. what will be the net vertical force on the box? 3. what force could be applied to the box to make the net force in the horizontal direction zero? explain. 4. suppose a force of 25n to the right is added to the box. what will be the net force to the right?
