Buffer solutions with the component concentrations shown below were prepared. Which of them should have the highest pH?

refer to the above diagram. other things equal, an increase of product price would be shown as:

The 10-turn loop of wire shown in the figure lies in a horizontal plane, parallel to a uniform horizontal magnetic field, and carries a 2.0 current. The loop is free to rotate about a nonmagnetic axle through the center. A 50 mass hangs from one edge of the loop.

A solid disk of unknown mass ad known radius R is used as a pulley in a lab experiment, as shown. A small block of mass m is attached to a string, the other end of which is attached to the pulley and wrapped around it several times. The block of mass m is released from rest and takes a time t...

Marks: 1 A 10-kg block on a horizontal frictionless surface is attached to a light spring (force constant = 0.80 kN/m). The block is initially at rest at its equilibrium position when a force (magnitude P = 80 N) acting parallel to the surface is applied to the block, as shown. What is the speed...

The figure shows a rectangular array of charged particles fixed in place, with distance a = 39.2 cm and the charges shown as integer multiples of q1 = 3.33 pC and q2 = 5.78 pC. With V= 0 at infinity, what is the net electric potential at the rectangle's center?
