How subcooling increase the COP of vapour compression refrigeration?
The sub-cooling or under-cooling in the saturated liquid line increases the refrigeration effect or cooling effect, thus the COP of VCR system increases.
What does ray mean in science?
A straight line used to represent a light wave
Why can you represent light rays using a ruler?
Because light rays travel in straight line just like a ruler/scale. We can represent it with anything which is straight like a ruler...
Two vectors which do not lie along the same line represent what kind of motion?
Two-dimensional motion
What type of path does a moving object follow in the absence of a force?
The path of a body not acted on by a force is a path without acceleration, a straight line. A straight line can be a flat line zero velocity or a slant line constant velocity. It cannot be a curved line, acceleration, changing velocity.
What does a flat line on a velocity -time graph represent?
A flat line would indicate a constant velocity, no change in speed.
What does a straight line on an ECG represent?
A flat section of line indicates no muscular activity in the heart at that particular instant; a constantly flat line indicates heart failure.
What does a flat line represent on a speed time graph?
Motion at a constant speed - no acceleration or deceleration.
Why are the grid lines in north America curved and how must grid references be read?
There is no way to represent a round object on a flat surface without having distortion occur on a projection (map). Lines of longitude are curved because the Earth is asphere. When pinpointing a longitude line, your finger must curve around with the line itself as it curves
What is non- linear plot?
A linear line is one that is straight with no curves. A non-linear line would not be perfectly straight and can have many curves.
How do you write number 1?
To write the number 1, start by drawing a straight vertical line from top to bottom. It should be a tall, thin line with no curves or loops. You can also use the numeral "1" to represent the number.
What shape has no corners no faces but has curves?
A curved line.
What shape is formed by curves line segment or both?
hexagon
Where is A flat on the staff?
second space with flat sign. or high a flat is line above fifth line with flat sign
Intersection of two curves at right angles?
Can happen if tangent line is perpendicular to normal line.
Is a circle a one dimensional line or 2?
one dimensional line that curves into 2 dimensions
What is difference between circle and line?
A line is straight and never-ending. A circle curves and is round.
