Answer:

Explanation:
Acceleration is the change in velocity over time.

The object accelerates <em>from</em> 45 meters per second <em>to </em>10 meters per second in 5 seconds. Therefore,

Substitute the values into the formula.

Solve the numerator.

Divide.


The acceleration of the object is -7 meters per square second. The acceleration is negative because the object's velocity decreases and the object slows down.
Sodium (Na) is a Alkali metal so that's the answer

44 x 12. I got the 12 from the total of 12 months in a year.
44 > 40
x
12 > 10
----------
The way my teacher taught me how to estimate is look at the neighbor to 44 and 12. The only time 44 can become 50, is when the neighbor is 5 or up. Same thing for 12. Now, multiply 40 and 10.
40 x 10 = 400.
Therefore, your estimate is 400.
The real answer is 520 breaths.
