Why is the following situation impossible? A barge is carrying a load of small pieces of iron along a river. The iron pile is in the shape of a cone for which the radius r of the base of the cone is equal to the central height h of the cone. The barge is square in shape, with vertical sides of length 2r, so thatthe pile of iron comes just up to the edges of the barge. The barge approaches a low bridge, and the captain realizes that the top of the pile of iron is not going to make it under the bridge. The captain orders the crew to shovel iron pieces from the pile into the water to reduce the height of the pile. As iron is shoveled from the pile, the pile always has the shape of a cone whose diameter is equal to the side length of the barge. After a certain volume of iron is removed from the barge, it makes it under the bridge without the top of the pile striking the bridge.
A piece of wire of length 1.00 m is cut into two parts, one of which is bent into a shape of a circle and the other into the shape of a square. How should the wire be cut so that the sum of the enclosed areas is a minimum?
Global warming is a cause for concern because even small changes in the Earth’s temperature can have significant consequences. For example, if the Earth’s polar ice caps were to melt entirely, the resulting additional water in the oceans would flood many coastal areas. Model the polar ice as havingmass 2.30 × 1019 kg and forming two flat disks of radius 6.00 × 105 m. Assume the water spreads into an unbroken thin, spherical shell after it melts. Calculate the resulting change in the duration of one day both in seconds and as a percentage.

Instead, some medical devices use the Hall effect, taking advantage of the fact that the blood flowing through a vein contains a considerable number of free ions. Model the vein in a patient's arm to be of rectangular cross section, as shown in the figure, with a width w=4.00 mm and height ℎ=3.35 mm. The entire section of the vein is immersed in a constant magnetic field of ?=0.0955 T, pointing horizontally and parallel to the width. A medical device constantly monitors the resulting Hall voltage. Suppose that medical precautions mandate that the speed of the blood flow for this particular component of the body should never drop below 21.40 cm/s. At what minimum Hall voltage VH, in millivolts, should the medical device be designed to trigger an alarm to the medical staff? ?H= mVarrow_forward
