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
Explanation:
The given data is as follows.
mass = 227.8 kg, volume = 0.1189
It is known that formula for volume of a sphere is and density is as follows.
Density = ........ (1)
=
= 1915.895
Hence, putting the given values into equation (1) as follows.
Density =
1915.895 =
= 227.8
r = 0.305
Thus, we can conclude that radius of the sphere is 0.305 .
Yeah You are doing it correct
Shale, sandstone, and limestone are the most commoc types of sedimentary rocks. They are formed by the most common mineral that is found on or near the surface of the Earth
Answer:
The number of bright fringes per unit width on the screen is,
Explanation:
If d is the separation between slits, D is the distance between the slit and the screen and is the wavelength of the light. Let x is the number of bright fringes per unit width on the screen is given by :
is the wavelength
n is the order
If n = 1,
So, the the number of bright fringes per unit width on the screen is . Hence, the correct option is (B).
