What happens if a hot air balloon lands in your yard? As a general rule, pilot or crew chef are supposed to ask the property owner if it is OK to land on private property and take the balloon down. If they did not ask, they are basically trespassing. Trespassing pilot and crew may harm […]

What is the magnetic field in the center of the solenoid? For the first part, since the solenoid is long we can approximate the magnetic field inside to be uniform and is given by Bz=μ0NI, so we can say that the magnetic field at the center is also μ0NI. What is the ferrite core used […]

Do airplanes have constant velocity? Since there is no net external force on the aircraft, the aircraft will maintain a constant airspeed as described by Newton’s First Law of Motion. However, if the forces become unbalanced, the aircraft will move in the direction of the greater force. How is an aircraft held into a turn? […]

How many atoms are in FCC? four atoms What are 111 planes? The symbol (111) represents Miller indices for an infinite set of parallel planes, with intercepts 1, 1 & 1 along the three crystallographic axis (unit lattice parameter along these), which pass through lattice points. On what planes of a bcc structure can the […]

What does increase in demand mean? An increase in demand means that consumers plan to purchase more of the good at each possible price. c. A decrease in demand is depicted as a leftward shift of the demand curve. d. A decrease in demand means that consumers plan to purchase less of the good at […]

How gravity affects walking up and down the stairs? 3 Answers. You have to lift up your body mass under the presence of gravity, so you have to overcome the force of gravity. While climbing up the stairs you have to put force on ground, more then your weight, which put same force but in […]

What is the partial pressure of oxygen at sea level? 160 mm Hg How do you find the partial pressure of CO2? Calculate the partial pressures for each gas. For the partial pressure of carbon dioxide, we multiply 0.2 mol by our constant of 0.0821 and our temperature of 310 degrees K, then divide by […]

Why are telescopes limited? The resolution of an optical imaging system – a microscope, telescope, or camera – can be limited by factors such as imperfections in the lenses or misalignment. Is the human eye diffraction limited? The human eye is close to being fully diffraction-limited, at least for photopic (cone-based) vision at the center […]

How can detergents cause pollution? Phosphates in detergents can lead to freshwater algal blooms that releases toxins and deplete oxygen in waterways. When the algae decompose, they use up the oxygen available for aquatic life. Does Soap pollute rivers? All soaps, unfortunately even biodegradable ones, can contaminate fresh water sources. Materials are usually deemed biodegradable […]

What is a bias? Bias is a disproportionate weight in favor of or against an idea or thing, usually in a way that is closed-minded, prejudicial, or unfair. Biases can be innate or learned. People may develop biases for or against an individual, a group, or a belief. In science and engineering, a bias is […]
