Answer:
A
P V = N R T is the ideal gas law
P V = k T since N and R are constant for a particular volume of gas
V = k T if the pressure of the gas remains constant
(I believe this is also called Charles' Law)
This formula is valid for variations of volume and temperature only.
Answer:
The star is too distant to be measured by parallax method. This happens when parallax angle is of the order of the least count of measuring system or less than that.
Explanation:
The incorrect answer is C
Answer:
The right answer is B: they use toners to create high quality outputs
Explanation:
The workflow of a laser printer is simple. It works with an ink formed by pigments, where the laser engraves the entire content in a photosensitive cylinder, which must be copied through an electrostatic charge. This cylinder passes through the toner so that the pigments stick together. Thus, the paper will come into contact with the cylinder, where the dust will fall and be fixed on the paper with the help of the same heat of the laser.
<u>adventages</u>
- They are silent when printing, compared to injection printers.
- The quality is much better than those made by ink printers.
- Prints are more comfortable than ink.
- They are faster and more powerful.
Disadventages
- If you print a large batch of sheets in one fell swoop, they may become blackened or jammed.
- It is more expensive than ink printers or injection printers.
- A long running laser printer may overheat.
- It produces paper jams.
Explanation:
SI system is advantageous over mks system because SI system is intended to extend by its definition and has 7 base which is more than MKS system .
