How do you calculate the normal force of an elevator? Consider the normal force acting on you from the elevator: N = mg if the elevator is at rest or moving at constant velocity. N = mg + ma if the elevator has an upward acceleration. N = mg – ma if the elevator has […]

How does the amount of gas affect gas pressure?
How does the amount of gas affect gas pressure? Summary. An increase in the number of gas molecules in the same volume container increases pressure. A decrease in container volume increases gas pressure. An increase in temperature of a gas in a rigid container increases the pressure. What are the factors affecting gas pressure? Temperature, […]
What happens if air resistance is not negligible?
What happens if air resistance is not negligible? Gravity. The most remarkable and unexpected fact about falling objects is that, if air resistance and friction are negligible, then in a given location all objects fall toward the center of Earth with the same constant acceleration, independent of their mass. What is the size of the […]
What does T1 and T2 mean on MRI?
What does T1 and T2 mean on MRI? The most common MRI sequences are T1-weighted and T2-weighted scans. T1-weighted images are produced by using short TE and TR times. Conversely, T2-weighted images are produced by using longer TE and TR times. In these images, the contrast and brightness are predominately determined by the T2 properties […]

Which tool would best be used for measuring the temperature of the classroom? thermometers What way would a digital thermometer be preferable to those from a liquid based thermometer? In what way would readings from a digital thermometer be preferable to those from a liquid-based thermometer? NOT Readings from a digital thermometer are less prone […]
What is the importance of industrialization?
What is the importance of industrialization? The development of various industries leads to direct increase in production and productivity within the country. Industries create an environment where more manpower’s are utilized. Hence, the surplus labour from agriculture can easily absorb within the industries bring more income opportunities in the country. What are the 5 factors […]

What is the best magnification for telescopes?
What is the best magnification for telescopes? For most purposes, a telescope’s maximum useful magnification is 50 times its aperture in inches (or twice its aperture in millimeters) . So you’d need a 12-inch-wide scope to get a decent image at 600×. And even then, you’d need to wait for a night when the observing […]
