What is the coefficient of static friction? The coefficient of static friction is the ratio of the maximum static friction force (F) between the surfaces in contact before movement commences to the normal (N) force. How do you find the minimum coefficient of static friction? To find the minimum coefficient of static friction between two […]
Are combustion engines more efficient?
Are combustion engines more efficient? How efficient are engines? Combustion engines are stupefyingly inefficient. Most diesel engines do not even have a thermal efficiency of 50%. Of every gallon of diesel burned by a combustion engine, less than half of the energy generated becomes mechanical energy. How long will internal combustion engines be around? The […]
Does energy have momentum?
Does energy have momentum? Light indeed carries energy via its momentum despite having no mass. Public Domain Image, source: Christopher S. Baird. In the above equation, E is the total energy of the particle, p is the momentum of the particle (which is related to its motion), c is the speed of light, and m […]
Why do they say feels like temperature?
Why do they say feels like temperature? The “feels like” temperature is a measurement of how hot or cold it really feels like outside. For example, skin that is exposed to wind and cold temperatures will make a person feel that it is colder outside than it really is because heat is drawn away from […]
How do you know if a gas is produced in a chemical reaction?
How can I measure 5G radiation?
How can I measure 5G radiation? Electromagnetic Field (EMF) meters are used to measure RF radiation. With 5G deployments are growing worldwide, the obvious question is – which EMF meters are best suited for measuring 5G signals? Our recommendation for the best EMF meter is the TriField EMF Meter. What is the best radiation detector […]
Which of the following is a postulate of the kinetic molecular theory of gases?
Which of the following is a postulate of the kinetic molecular theory of gases? As applied to gases, the kinetic molecular theory has the following postulates: Gases are composed of very tiny particles (molecules). The actual volume of these molecules is so small as to be negligible compared with the total volume of the gas […]
Why were Russian peasants so poor?
Why were Russian peasants so poor? The reforms in agricultural also disappointed the peasants. By 1900 around 85 per cent of the Russian people lived in the countryside and earned their living from agriculture. The nobility still owned the best land and the vast majority of peasants lived in extreme poverty. Why was there a […]
Is the tail light the same as the blinker?
What is neap tide simple?
What is neap tide simple? A neap tide—seven days after a spring tide—refers to a period of moderate tides when the sun and moon are at right angles to each other. During full or new moons—which occur when the Earth, sun, and moon are nearly in alignment—average tidal ranges are slightly larger. This occurs twice […]
