Answer:
C. 
Explanation:
The acceleration of an object can be found using the equation:

where
v is the final velocity
u is the initial velocity
t is the time it takes for the velocity to change from u to v
In this problem:
u = 30 m/s is the initial velocity of Angelica
v = 84 m/s is the final velocity
t is the time
Substituting into the equation, we find the acceleration:

Answer:

Explanation:
Given:
- Initial temperature,

- initial volume,

- final temperature,

- volumetric coefficient of thermal expansion for gasoline,

- volumetric coefficient of thermal expansion for steel,

<u>Now the increment in the volume of the container:</u>



<u>and the increment in the volume of the gasoline:</u>



<u>Hence the difference in the increment of the two volumes:</u>


of the gasoline spills out of the container in this case.
Yes, this is an example of a force because a force is a push or pull.
