An object moving in the +x direction experiences an acceleration of +2.0 m/s2. This means the object (a) travels 2.0 m in every second. (b) is traveling at 2.0 m/s. (c) is decreasing its velocity by 2.0 m/s every second. (d) is increasing its velocity by 2.0 m/s every second.

This question is related to the concept of acceleration.

The correct answer is "(d) is increasing its velocity by 2.0 m/s every second".

The acceleration of an object is defined as the rate of change of its velocity over a given interval of time. Mathematically, acceleration is defined as the change in velocity of an object divided by the time interval taken for that change in velocity.

The Positive sign of the acceleration means the change in velocity is positive and the velocity is increasing, while the negative sign indicates a decrease in velocity.

Hence, an acceleration of 2 m/s² means that the velocity of the object is increasing by 2 m/s every second.

(d) is increasing its velocity by 2.0 m/s every second.

Explanation:

Acceleration is the change in velocity over time.

An acceleration of 2.0 m/s/s means the object's velocity is increasing 2.0 m/s per second.

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
