Answer:
14,538 trains in the world.
Explanation:
There could be more in the world because they could make more or there could be less??
Answer:

Explanation:
Carnot cycle
Carnot cycle have four process
1. Iso thermal expansion
2.Reversible adiabatic expansion
3. Iso thermal compression
4.Reversible adiabatic compression
This is ideal cycle for all work producing devices.All devices have efficiency less than Carnot cycle. Because in Carnot cycle all process is reversible process.
Efficiency of Carnot cycle given as

But temperature must be in Kelvin
So


Answer:
remain the same constant
Explanation:
if a small gear is making 5 rpm turning a big gear thats making 1 rpm the bug gear is making lots of torque but if its going the opposite way its much harder to turn the big gear 1 rpm just to make the little gear do 5 rpm and it makes way less torque if thre both the same size there ging to stay the same speed
The technician should start by checking the temperature rise across the indoor coil.
