The normal force applied by the seat on you is less than mg at the top and larger than mg at the bottom. On a roller coaster, for instance, you feel very light at the top of loops, but heavier than usual at the bottom. IF it is greater than or equal to 20 but less than 50, then times it by 2 Water Use and. In more extreme situations this is much more obvious. Frequently Asked Questions About Energy Efficiency Nov 6. So, you actually feel a little heavier than usual when the elevator accelerates upward, and lighter than usual when the acceleration is down. Would the period of the block9s oscillation on the Moon be greater than, less than, or equal to. The normal force is equal to your apparent weight. The center of mass of the block again oscillates between and. N = mg - ma if the elevator has a downward acceleration.N = mg ma if the elevator has an upward acceleration.N = mg if the elevator is at rest or moving at constant velocity.The combined system of you elevator has two forces, a combined force of gravity and the tension in the cable.Ĭonsider the normal force acting on you from the elevator: The elevator's free-body diagram has three forces, the force of gravity, a downward normal force from you, and an upward force from the tension in the cable holding the elevator. Your free-body diagram has two forces, the force of gravity and the upward normal force from the elevator. The current at location A is (greater than, equal to, less than) the current at location B. Does not equalthe number on the left does not equal the number on the right 2 3. Greater than or equal tothe number on the left is greater than or equal to the number on the right 2 or 3 2. (a) 9.57 × 10 5 s 9.57 × 10 5 s (b) 0.045 s (c) 5.5 × 10 7 s 5.5 × 10 7 s (d) 3.16 × 10 7 s. Use the diagram to answer the following questions. Less than or equal tothe number on the left is less than or equal to the number on the right 2 or 3 3. For example, 7.9 × 10 2 s 7.9 × 10 2 s could be written as either 7.9 cs or 79 ms. Use metric prefixes to rewrite them so the numerical value is greater than one but less than 1000. options are : greater than, less than, equal to, true, or false This problem has been solved You'll get a detailed solution from a subject matter expert that helps you learn core concepts. (a) At what frequency is the magnitude a of the diaphragm's acceleration equal to g (b) For greater frequencies, is a greater than or less than g ' Last edited. The following times are given in seconds. The denominator is less than the numerator. In this situation there are no new forces acting when there is an acceleration - one or more of the forces simply change size to produce the acceleration. The textbook's question in its entirety reads: 'A loudspeaker produces a musical sound by means of the oscillation of a diaphragm whose amplitude is limited to 1.00 itex\mu m /tex. question 1 of 3 Which of the following identifies a fraction that is less than one The numerator is less than the denominator. the elevator has a downward acceleration (accelerating down, or decelerating while on the way up).the elevator has an upward acceleration (accelerating upward, or decelerating while on the way down). the elevator has no acceleration (standing still or moving with constant velocity).Sketch separate free-body diagrams for you, the elevator by itself, and the combined system of you plus the elevator for these three situations:
