___ acceleration occurs when an object speeds up

The acceleration that leads to the increase in the speed of the object is called as Positive acceleration.

Explanation:

The acceleration of a body is defined as the amount of change taking place in the magnitude of the velocity of the body in every second. The acceleration of the body is a vector quantity as it requires the direction along with the magnitude of change in the speed of the body.

If the acceleration of the body is acting in the direction opposite to the direction of motion of the body, then the acceleration tends to decrease the speed of the body and it is called as deceleration.

Whereas if the acceleration of a body is in the direction same as that of the direction of motion of the body, then the acceleration of the body increases the speed of the body and this acceleration is termed as the positive acceleration of the body.

Therefore, the acceleration of an object that tends to speed up the object must be acting in the direction same as the direction of motion of the body and therefore it is termed as the positive acceleration of the body.

Thus, The acceleration that leads to the increase in the speed of the object is called as Positive acceleration.

Explanation:

Acceleration is defined as the change in velocity over time.

When there is an increment or increase in the magnitude of velocity of a moving body then it is known as positive acceleration.

Whereas when there is a decrease in magnitude of velocity of a moving body then it is known as negative acceleration.

Thus, we can conclude that positive acceleration occurs when an object speeds up.

What does deposition mean in a sedimentary formation

Zinaida [17]

Answer:

Sedimentary rocks are types of rock that are formed by the deposition and subsequent cementation of that material at the Earth's surface and within bodies of water. Deposition means that all the sediments, soil, and rocks are all compressed (tightly pressed into each other) and create sedimentary rocks.

Explain what the star looks like to Jane

S_A_V [24]

The star looks like a desirable hunk of masculinity to Jane. But to John, the star looks like a wimpy momma's boy who might compete with him for Jane's attention. Jane and John have different impressions of the star because of their gender-specific instincts that have evolved during thousands of millenia of human evolution.

What is the total number of pounds of carbon dioxide that 2 trees remove from the air each year?

Vikentia [17]

Answer:

On average, one acre of new forest can sequester about 2.5 tons of carbon annually. Young trees absorb CO2 at a rate of 13 pounds per tree each year. Trees reach their most productive stage of carbon storage at about 10 years at which point they are estimated to absorb 48 pounds of CO2 per year.
