In which of the following situations would an object be accelerated? i. it moves in a straight line at constant speed. ii. it moves with uniform circular motion. iii. it travels as a projectile in a gravitational field with negligible air resistance.

III. It travels as a projectile in a gravitational field with negligible air resistance.

Explanation:

In this case, the body is under the effect of a force, therefore, it accelerates. This is due to the gravitational field, which is independent of its mass. Therefore, the body is under the effect of the acceleration of gravity, which is constant throughout the trip.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
