What are the factors affecting thrust? FACTORS AFFECTING THRUST The factors that affect the thrust of a gas turbine engine include air density, airspeed/ram effect and engine RPM. Why does thrust decrease as airspeed increases? The faster the aircraft speed, the less acceleration is being created on the intake air. Therefore thrust decreases with increasing […]
Why do ammeters burn when connected in parallel?
Why do ammeters burn when connected in parallel? Since most ammeter’s measure current through a very small internal resistance; when connected in parallel nearly all the current will travel through the ammeter loop rather than the circuit. This is because the current will choose the path of the least resistance. Hence the ammeter burns. Why […]

What is the function of hammer anvil stirrup?
What is the function of hammer anvil stirrup? Vibrations of the eardrum are in turn translated into oscillations of tiny bones (ossicles) found within the middle ear. The Hammer, Anvil, and Stirrup magnify the oscillations and relay this information to the chamber of the inner ear. What is a hammer in a ear? In ear […]

What is the value of science in our life? In other words, science is one […]
What is non-probability sampling with examples?
What is non-probability sampling with examples? In non-probability sampling, the sample is selected based on non-random criteria, and not every member of the population has a chance of being included. Common non-probability sampling methods include convenience sampling, voluntary response sampling, purposive sampling, snowball sampling, and quota sampling. What is an example of a non random […]
What would happen if there was no convection current in the mantle?
What would happen if there was no convection current in the mantle? If Earth had no convective currents, that would mean the inner Earth has solidified, therefore, we would not have plate tectonics. Our Earth’s crust is made up of plates of varying sizes that move very slowly around the planet over time, this theory […]
