Answer : is " c "
Because never stand on scale with a single foot, because some minor changes may come at starting, but our weight will show correctly, on some of the weighing scales, because our body weight is shows on that.

You are standing on a bathroom scale and you measure the weight to be 120 lb. You then take the scale onto an elevator and stand on the scale as the elevator accelerates, during which the reading on the scale decreases to 90 lb. Which of the following statements about the elevator could be true? A. The elevator is moving upward at 2 m/s while accelerating downward at 2.45 m/s^2. B. The elevator is moving downward at 4 m/s while...

Suppose Arturo is standing on a spring bathroom scale in an elevator, which is at rest, on the 15th floor. What is his acceleration? What forces are acting on him? What is the reading (in Newtons) on the bathroom scale if he has a mass of 150 kg? (Draw it out and Label it) Now imagine disaster - the rope holding the elevator snaps, there are no safety features, and the elevator plunges down the shaft in free fall. Herrera...

On the surface of a planet, you step on a bathroom scale and observe a reading of 810 N. You then board a de-elevator that goes to the center of the planet. On the way down, you stop, weigh yourself again and observe a reading of 400 N. How far below the planet's 'sea level' have you decended in km? Assume the planet radius and mass are 6880 km and 8.2E24 kg, respectively.

On the surface of a planet, you step on a bathroom scale and observe a reading of 1980 N. You then board a de-elevator that goes to the center of the planet. On the way down, you stop, weigh yourself again and observe a reading of 830 N. How far below the planet's 'sea level' have you decended in km? Assume the planet radius and mass are 13440 km and 6.1 E25 kg, respectively.

E. Suppose you are standing on the scale in the elevator and the
elevator is accelerating downward with
an acceleration smaller than 9.8 m/s2
i. Draw free-body diagrams of yourself, the scale, and the floor
of the elevator where it interacts
with the scale.
ii. How must the magnitude of the force exerted by the scale on
you compare with your own
weight?
iii. How must the reading on the scale compare with the reading
you make when the elevator...

Suppose you are standing on a weighing scale in an elevator that accelerates downward with a magnitude of 9.8 m/s2. The reading of the scale a) is zero b) is less than when the elevator was st rest c) is greater than when the elevator was at rest d) is the same as when the elevator was at rest e) none of these

Part A Astronauts in space cannot weigh themselves by standing on a bathroom scale. Instead, they determine their mass by oscillating on a large spring. Suppose an astronaut attaches one end of a large spring to her belt and the other end to a hook on the wall of the space capsule. A fellow astronaut then pulls her away from the wall and releases her. The spring's length as a function of time is shown in the figure (Figure 1)....
