What are the major areas where physics contributes significantly?
I believe every area because physics about understanding. for example even though thermodynamics was found whilst trying to make a steam engine more efficient it can help us to understand our sun and solar system
Explain whether or not a heat engine could be made 100 percent efficient by eliminating friction?
Even if the friction were totally eliminated, a heat engine still could not convert heat completely into work and be 100 percent efficient. Instead, the efficiency of an internal combustion engine depends on the difference in the temperature of the burning gases in the cylinder and the temperature of the burning gases in the cylinder and the temperature of the air outside the engine.
A 30-efficient car engine accelerates the 2000 car from rest to 20?
666.7kj
What temperature is required to transfer waste heat to the environment for an heat engine to be 100 percent efficient?
273k
Why were the laws of thermodynamics developed?
For the same reason they study other branches of science: It helps us understand how the world around us works, helps predict what will happen if we carry out certain actions, and therefore helps in the design of technology.
Steam engine is used in what field of science?
Thermodynamics
Why were the laws of thermodynamics devloped?
to help improve the steam engine
Which engine is more efficient diesel engine or gasoline engine?
Diesel engines are more efficient than gasoline engines.
What is more efficient the gasoline engine or diesel engine?
The diesel is more efficient but more expensive to build.
What is the carnot statement of the second law of thermodynamics?
The efficiency of a quasi-static or reversible Carnot cycle depends only on the temperatures of the two heat reservoirs, and is the same, whatever the working substance. A Carnot engine operated in this way is the most efficient possible heat engine using those two temperatures
The 2nd law of thermodynamics has three forms?
It has several forms, all of which are more or less equivalent, even though they don't seem so, at first glance. For example:No heat engine can be more efficient than a theoretical Carnot engine. In a closed system, entropy can never decrease.There are irreversible processes.
How can you make sentences using the 'efficient'?
The engine was cleaner and more efficient.

Which is more efficient a petrol engine or a diesel engine?
It will depend upon the conditions. Under normal operating conditions a diesel engine is more efficient than a petrol engine.
If an automobile had a 100 efficient engine would it exhaust the surroundings?
f an automobile had a 100 efficient engine would it exhaust the surroundings?
Which engine is the most efficient in terms of compression ratios?
Diesel engine
