Answer:
The value is 
Explanation:
From the question we are told that
The efficiency of the carnot engine is 
The efficiency of a heat engine is 
The operating temperatures of the carnot engine is
to 
The rate at which the heat engine absorbs energy is 
Generally the efficiency of the carnot engine is mathematically represented as
![\eta = [ 1 - \frac{T_1 }{T_2} ]](https://tex.z-dn.net/?f=%5Ceta%20%3D%20%20%5B%201%20-%20%5Cfrac%7BT_1%20%7D%7BT_2%7D%20%20%5D)
=> ![\eta = [ \frac{T_2 - T_1}{T_2} ]](https://tex.z-dn.net/?f=%5Ceta%20%3D%20%20%5B%20%5Cfrac%7BT_2%20-%20T_1%7D%7BT_2%7D%20%5D)
=> 
Generally the efficiency of the heat engine is

=> 
Generally the efficiency of the heat engine is also mathematically represented as

Here W is the work done which is mathematically represented as

Here
is the heat exhausted
So

=> 
=> 
Resistance is where you try to stop something from happening or trying to stop something in general
Answer:
10 Joule
Explanation:
The solution and answer are well written in the Pic above.
Answer: A physical change can be a change in size, shape, or color.
Explanation:
One type of physical change is a phase change. Consider water for example, if liquid water evaporated into a vapor, a phase change occurred. A phase change is a type of physical change. The difference between a physical change and chemical change is that a physical change doesn't change the substance identity. A chemical change can however change the identity of the substance.
10,000 meters: 1,000 meters in every kilometer.
