I may not be completely sure but compare those 2 things together and you should find your answer.
Answer:
hello your question is incomplete attached below is the complete question with the options
answer : Doubling the Diameter increases the heat transfer rate by a factor of 4 ( B )
Explanation:
The heat transfer in the axial direction of the cylinder can be calculated/determined as attached below

= 4
( This shows that Doubling the diameter increases the heat transfer rate by a factor of 4 )
Answer:
0.90m/s²
Explanation:
Given parameters:
Initial speed = 6miles/hr
Final speed = 12miles/hr
Time taken = 3 seconds
Unknown:
Acceleration = ?
Solution:
Acceleration is the rate of change of velocity with time. It is mathematically given as:
Acceleration = 
We need to convert miles/hr to meters/seconds
Initial speed = 6 x
x
x 
= 2.68m/s
Final speed = 12 x
= 5.37m/s
Acceleration =
= 0.90m/s²
