Is the state in which no thermal energy transfer occurs because both substances are at the same temperature? Temperature is a measure of the average kinetic energy of the atoms or molecules in the system. The zeroth law of thermodynamics says that no heat is transferred between two objects in thermal equilibrium; therefore, they are […]
What is the perfect crash?
What is the perfect crash? The “Perfect” Crash Surviving a crash is all about kinetic energy. When your body is moving at 35 mph (56 kph), it has a certain amount of kinetic energy. After the crash, when you come to a complete stop, you will have zero kinetic energy. How does technology affect driving? […]
Why is oxygen not brittle?

Urban Drainage Basins. Storm Surges and Tsunamis. Channels with Steep Sides. A Lack of Vegetation. Melting Snow and Ice. What are the types of […]
What would a perpetual motion machine be worth?
What would a perpetual motion machine be worth? Because it cannot be constructed, because of the physical law of conservation of energy. And physical laws are not about legality. You cannot violate them, because they are basic facts about the universe. The worth of a perpetual motion machine is zero. Is the drinking bird a […]
Which is the limitation of flat plate collector from following?
Which is the limitation of flat plate collector from following? The principal disadvantage of a flat plate collector is that because of the absence of optical concentration, the area from which heat is lost is large. Also due to the same reason high temperatures cannot be attained and as a result the collection efficiency is […]
What is the potential energy of the car?
What is the potential energy of the car? The potential energy of the position of the car at the top of the hill is getting converted into kinetic energy. Where “g” is the standard acceleration of gravity which equals 9.8 m/s2. The height is determined based on the height the object could potentially fall. What […]
What is the difference between religion and ethnicity?
What is the difference between religion and ethnicity? a. Explain the difference between an ethnic group and a religious group. An ethnic group is a group of people who share cultural ideas and beliefs that have been a part of their community for generations. A religious group shares a belief system in a god or […]
Is there sharks in Antarctica?
Is there sharks in Antarctica? These species, which are frequently found in shallow water, would struggle crossing the deep ocean surrounding the southernmost continent. Thus, no sharks in Antarctica… yet. Antarctic seawater temperatures are on the rise, and with this rise comes new visitors. What is the biggest land animal in Antarctica? Belgica antarctica What […]
