What is the cause of resistance? Resistance is caused in a conductor by the free electrons. These free electrons collide with each other and with the ions and atoms that oppose their free movement. This obstruction is known as resistance. Does temperature increase resistance? As electrons move through a metal conductor, some collide with atoms, […]

Who is liable if roofer falls off my roof? Legally, the responsibility varies from case to case. There are cases where the building owner may be legally liable for the incident. For example, if the incident has been proven to be caused by the building owner’s negligence, they are liable. You should have a contract […]

How does the kinetic theory explain Charles Law? Kinetic Molecular Theory states that gas particles are in constant motion and exhibit perfectly elastic collisions. Kinetic Molecular Theory can be used to explain both Charles’ and Boyle’s Laws. The average kinetic energy of a collection of gas particles is directly proportional to absolute temperature only. What […]

Is gold used in semiconductors? A good conductor of heat and electricity, it is also the most malleable and ductile of all metals. Gold is used in many aspects of semiconductor manufacturing, particularly in the assembly or packaging processes. Its most widespread use is in wirebonding. Why is gold used in motherboards? Principally used in […]

What are the 5 major divisions of physical science? Terms in this set (33) Five major divisions of physical science. Physics, Chemistry, Astronomy, Meteorology and Geology. Science. An organized body of knowledge about the natural universe. Scientific Method. Elements of Scientific Method. Mechanics. Standard Unit. System of Units. Length. Which of the following is an […]

How do I filter rows instead of columns in Excel? So you can follow the steps. Select the area where you want to sort values. Click the button “Sort & Filter” in the ribbon. In the menu, click the option “Custom Sort”. In this window, click the “Options”. Now you will see another new window. […]

Does gravitational force increase with distance? Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases. What happens to the […]

How many times more light can the telescope gather than the human eye? So the telescope can gather light for 900 times longer than the eye, to make a single image! The long exposure time of the telescope’s camera enables it to gather much more light than the eye. This enables telescopes to detect much […]

Can we land on an asteroid? Landing. Asteroids are not large enough to produce significant gravity, making it difficult to land a spacecraft. This technology allowed for the orientation control and orbit control of the spacecraft that guided it to land on Ryugu. How could we redirect an asteroid? Under consideration for deflecting an asteroid […]

Which best describes a difference between transformations in power plants and dams? The difference between the energy transformations in power plants and dams would be that dams are the ones who uses mechanical energy to produce electricity. It uses turbines to convert mechanical to electrical. Which best describes a difference between energy transformations in power […]
