A rectangular vessel measurements 5 cm by 15 cm. Ethanol of density p = 810 kg. m-3a) calculate is poured into the vessel to a depth of 5.5 cm [the density of water is 1000 kgm-3, atmospheric pressure is 101300 pa] i. the pressure due to the ethanol

iii the total pressure of the liquid on the base of the container

iii. the force ethanol exerts at the botton the tank

b) determine the relative density of ethanol​

A10 kg box initially at rest is pulled 18 meters across a horizontal, frictionless surface by a 40 n force. what is the block’s final velocity over the 18 meters?

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
