Answer:
219.9208 m
Explanation:
The new length is given by
New length= Original length *(1-Temperature change*coefficient of
thermal expansion of steel)
Here, the change in temperature is 
New length= 
Therefore, the new length will be 219.9208 m
Speed = m/s
Velocity can be negative, but speed cannot.
70 - 68 = 2
2/14 = 0.143 m/s
I think it comes from the stores energy from the gravity
Divide the change in speed by the time for the change.
Answer:
B.
Explanation:
The water collects in the ocean; it is then evaporated by the sun. After evaporation the water turns into water vapor, it then condenses to form clouds.
