The average acceleration is 
Explanation:
<u>Uniform Acceleration
</u>
When an object varies its velocity at the same rate, the acceleration is constant.
The relation between the initial and final speeds is:
Where:
vf = Final speed
vo = Initial speed
a = Constant acceleration
t = Elapsed time
The acceleration can be calculated by solving for a:
The Indy 500 race car increases its speed from vo=4 m/s to vf=36 m/s in t=4 s. Thus, the average acceleration is:
The average acceleration is
<u>100° C</u> she can expect once the water begins to boil.
<u>Option: B</u>
<u>Explanation:</u>
The boiling point for water at 1 pressure atmosphere of sea level is 212 ° F or 100 ° C. That value isn't a fixed. Water's boiling point is dependent on the ambient pressure, which varies based on elevation. At a lower temperature, water boils as one gains altitude like getting higher on a hill, and boils at a higher temperature if one increases the atmospheric pressure of returning to or below sea level.
It also relies upon the water's purity. Water containing contaminants like salted water boils at a level higher than pure water. This effect is called acceleration of the boiling point and is one of the material's colligative features.
Answer:
Because it is said that the earth rotates and revolves around the sun and moon so it is impossible for the earth not to be spinning.
