It is a unified theory than can describe whole world.
Answer:
The length traveled by an object moving in any direction or even changing direction is called distance. The location of an object in a frame of reference is called position. For straight line motion, positions can be shown using a number line. The separation between original and final position is called displacement
Explanation:
good luck
Because the wall reflects sound waves to your ears bouncing off of the walls, even if it's in another room.
Answer:
Explanation:
a. Internal energy and the relative specific volume at are determined from A-17:.
The relative specific volume at is calculated from the compression ratio:
#from this, the temperature and enthalpy at state 2, can be determined using interpolations and . The specific volume at can then be determined as:
Specific volume,:
The pressures at is:
.The thermal efficiency=> maximum temperature at can be obtained from the expansion work at constant pressure during
b.Relative SV and enthalpy at are obtained for the given temperature with interpolation with data from A-17 :
Relative SV at is
=
Thermal efficiency occurs when the heat loss is equal to the internal energy decrease and heat gain equal to enthalpy increase;
Hence, the thermal efficiency is 0.563
c. The mean relative pressure is calculated from its standard definition:
Hence, the mean effective relative pressure is 674.95kPa
The choices are confusing. Air, oil, and alcohol are fluids at any reasonable temperature. Dry cement is not.
