Of the following given choices;
A. A higher fertility rate
B. Less access to medicine
C. A new source of fresh water
D. A higher birthrate
The answer is; C
Carrying capacity is the maximum population size than habitat or environment can sustain indefinitely because it is able to replenish its resources. Limiting factors to carrying capacity of an ecosystem include resources such as food, water, and space.
Answer:
M1L2T-2
Explanation:
In the equation above 1/2 is a constant and constants do not affect the dimensional formula of any quantity.
For a certain interval of time, an object is acted on by a constant non-zero force. For this interval of time . . . . .
A. The object is at rest. No. From F=ma, if F is not zero, the object can't remain at rest.
<em>B.</em> <em>The object's velocity changes.</em> <em>Yes.</em> From F=ma, if F is not zero, there must be acceleration.
C. The object's velocity can only increase. No. It might decrease.
D. The object is moving with constant velocity. No. From F=ma, if F is not zero, there must be acceleration.
<em>E.</em> <em>The object is accelerating.</em> <em>Yes.</em> From F=ma, if F is not zero, there must be acceleration.
Answer:
On average a galaxy has, between <u>800 billion and 3.2 trillion planets.</u>
Newton's 2nd law of motion says:
Force = (mass) x (acceleration).
In order to accomplish the task described in the question,
you would need
Force = (20 kilograms) x (the desired rate of acceleration) .
