From the question, we know that after 10 seconds are passed the velocity GOES DOWN.
Based on that, we can infer that the acceleration of the arrow will be negative.
in 10 seconds, the velocity goes down 30 meter/second, (65 - 35)
so it would be 30/10 = -3 m/s/s in the same direction of travel
Answer:
visible waves are needed for green plants to grow.
Explanation:
During photosynthesis, chlorophyll absorbs energy from blue- and red-light waves, and reflects green-light waves, making the plant appear green.
Answer:
Explanation:
<u>Functions</u>
When one magnitude depends on other (or others), we usually try to express them as a function which can contain any number of variables, constants, and operations.
The area of a circle is computed by the well-known formula
We are required to use function notation to express the area of a circle f(r) in terms of the radius r. If the radius is in cm, then the area is in .
The required function is
For a radius of 4.3 cm:
The purpose of an air filter is to purify the air around you removing particles such as dust from the air.
