Which one of the following does not accurately describe the universal gravitational law? (a) gravitational forces is proportional to the product of the two masses.(b)every object in the universe that has mass attracts every other object in the universe that has mass.(c)the object with the smaller mass does most of the moving because the object with the larger mass has too much inertia to move any noticeable amount.(d) gravitational force is proportional to the square of the distance between the centers of both bodies.

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?

Avertical clean glass piezometer tube has an inside diameter of d = 1 mm and is used to measure pressure in a horizontal pipe carrying water as shown. due to pressure in the pipe, the water at 20ο°c rises into the tube to a height h. if the water pressure in the pipe is p = 500 pa gauge, estimate the height h: (a) without considering surface tension (b) with surface tension (capillary) effects. the contact angle ο± can be assumed at 30 deg
