How does heat transfer from one object to another? Heat can be transferred in three ways: by conduction, by convection, and by radiation. Conduction is the transfer of energy from one molecule to another by direct contact. Convection is the movement of heat by a fluid such as water or air. Radiation is the transfer […]
Why is the electron transport chain so important?
Why is the electron transport chain so important? The ETC is the most important stage of cellular respiration from an energy point of view because it produces the most ATP. When a cell needs energy, it breaks the third phosphate group bond and uses the resulting energy. Which anaerobic process is responsible for producing ATP […]
What are the three major earth cycles?
What are the three major earth cycles? The three main cycles of an ecosystem are the water cycle, the carbon cycle and the nitrogen cycle. These three cycles working in balance are responsible for carrying away waste materials and replenishing the ecosystem with the nutrients necessary to sustain life. What is Earth’s natural cycle? The […]
What does the slope of velocity time graph represent?
What does the slope of velocity time graph represent? The slope of a velocity graph represents the acceleration of the object. So, the value of the slope at a particular time represents the acceleration of the object at that instant. Can you draw a graph for uniform motion? Distance-Time Graph for Uniform Motion Let’s draw […]
Why do rooms echo?
Is filming on a plane Illegal?
Is filming on a plane Illegal? For example, American Airlines’ photography policy strictly prohibits “photography or video recording of airline personnel, equipment, or procedures.” United, Delta and Southwest have similar policies. However, even if a passenger films without permission, there is no law against taking video or photographs on a plane. Can you take pictures […]
How do you remember thermodynamic relations?
How do you remember thermodynamic relations? A mnemonic used by students to remember the Maxwell relations (in thermodynamics) is “Good Physicists Have Studied Under Very Fine Teachers”, which helps them remember the order of the variables in the square, in clockwise direction. How do you remember Gibbs free energy? The equation often seen for Gibbs […]
Do Fitz and Simmons have babies?
Do Fitz and Simmons have babies? Child of Genius Alya Fitz was born halfway through the Earth year 2020, on the S.H.I.E.L.D. ship Zephyr One in deep space. Her birth was the result of her parents, genius engineer Leo Fitz and biochemist Jemma Simmons, taking a years-long break from building a time machine to aid […]
How much energy is in the atmosphere?
How much energy is in the atmosphere? On average, 340 watts per square meter of solar energy arrives at the top of the atmosphere. Earth returns an equal amount of energy back to space by reflecting some incoming light and by radiating heat (thermal infrared energy). How does energy transfer in a TV? A television […]
Which feature of a heating curve indicates a change of state?
Which feature of a heating curve indicates a change of state? The diagonal or the inclined lines shows the changes in terms of temperature, and the horizontal lines shows the changing of phases. What do you understand by change of state give two examples of change of state? The physical process where matter moves from […]
