The efficiency of an ideal Carnot heat engine can be written as:
where
is the temperature of the cold region
is the temperature of the hot region
For the engine in our problem, we have
and
, so the efficiency is
<span>3 meters east and 15 meters west evens out to 12 meters west. the answer is 12 meters west

Answer:
friction is when two objects tough with force basically. when an object is rubbed against something. when an object comes in contact with something else. or ig u can call it hot air rubbing off the inevitable force lol that works too , bud
whatever helps u rememeber
Answer:
when heavy atoms split the loss of mass is converted into kinetic energy
Explanation:
Answer:
Sound waves travel faster in a low-density gas
Explanation:
First of all, let's remind that sound waves are pressure waves: they consist of oscillations of the particles in a medium, which oscillate back and forth along the direction of motion of the wave (longitudinal wave).
The speed of sound in an ideal gas is given by the equation
where
is the adiabatic index of the gas
p is the gas pressure
is the gas density
From the equation, we see that the speed of sound is inversely proportional to the square root of the density: therefore, the lower the density, the faster the sound waves.
So, sound waves will travel faster in a low-density gas.
