Where is the rest of the sentence?
Answer:large
Explanation:
As the temperature increases, materials with large coefficients of linear expansion increases a lot in size
Acceleration = (change in speed) / (time for the change)
Change in speed = (end speed) - (start speed) = (15 m/s - 7 m/s) = 8 m/s
time for the change = 2 minutes = 120 seconds
Acceleration = (8 m/s) / (120 seconds)
Acceleration = 0.067 m/s²
20/45=0.4*100= 44.4 so the answer is..................................................
Answer: 44.4%
