Question

An N-tube contains both water and oil, as shown at right. Paints V and Y are at the same height in the N-tube, as are pointsX and Z. (Recall that the density of oil is less than that of water) Open to air Upper surface is the pressure at point x greater than, less than, or equal to the pressure at point Z? reater than ss than Oil e equal to Not enough information to answer this question. Is the pressure at point V greater than, less than, or equal to the pressure at point Y? reater than ss than * equal to Not enough information to answer this question Suppose that a 1 cm diameter hole were made in the upper surface of the N-tube, right above point Y Would the oil be forced out of the hole? Yes, the oil will be forced out of the hole No, the oil will not be forced out of the hole Not enough information to answer this question Consider a small volume of oil directly underneath where the hole will be made: compare the pressure right above and right below the hole. Ebmit Answer Incorrect. Tries 2/10 Previous Tries

Explanation / Answer

1. Pressure at point x is equal to the pressure at point z. Pressure is equal at the same level of water.

2. Pressue at Y is mre than V, since V is open to air its pressue is equal to the atmospheric pressure.

3. No, because the density of the oil is more than the density of water
