How does a pulley system give a mechanical advantage? Using multiple pulleys decreases the amount of force necessary to move an object by increasing the amount of rope used to raise the object. The mechanical advantage (MA) of a pulley system is equal to the number of ropes supporting the movable load. How are pulleys […]

What are the five steps in MIPS instruction execution?
What are the five steps in MIPS instruction execution? In general, let the instruction execution be divided into five stages as fetch, decode, execute, memory access and write back, denoted by Fi, Di, Ei, Mi and Wi. Execution of a program consists of a sequence of these steps. When the first instruction’s decode happens, the […]
What is the relationship between temperature and frequency?
What is the relationship between temperature and frequency? The intensity of wavelength increases with increase in temp and the wavelength itself decreases so the wavelength is inversely proportional to temp and the frequency is directly proportional to temp, but in case of sound waves frequency is not effected the change in speed is due to […]

How do you remove nitrates from wastewater?
How do you remove nitrates from wastewater? Nitrates can be removed by ion exchange using strong anionic resin in Cl- form. Reverse Osmosis is also efficient to remova nitrates, although the hydrophilic properties of the molecule does not allow an optimal removal. Biological denitrification is used in municipal waste water treatment plant. What things can […]
