Solutions to the 2014 Physics Exam paper
... WX: down, XY: no force, YZ: up, ZW: no force. Use Hand Rule with Field: Left to Right and the current going clockwise around the loop. For XY and ZW, the current is parallel to the field, so zero force. [ 1.5/ 2, 75 %] 1.2 N Using F = nBIl, F = 75 x 0.020 x 2.0 x 0.40 (1) = 1.2 N (1) [ 1.5/ 2, 75 %] ...

... 4. (15) Use cylindrical coordinates to calculate the divergence of a vector field u =(z x, 0, 0). Make sure the result agrees with the divergence calculated using Cartesian coordinates. Verify the divergence theorem for this field, with volume V equal to the part of the cylinder x2+y2≤4 lying in the ...

Problem-Based Learning for College Physics - PBL
... First, the PBL scenario should propose a lifelike problem in which the student is the central actor. Second, the problem structure must also include meaningful questions that have to be answered to solve the problem. However, these questions must not structure the problem in such a way that an algor ...

Mechanical Energy
... Mechanical energy is the energy which is possessed by an object due to its motion or due to its position. Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position). A moving car possesses mechanical energy due to its motion (kinetic energy). A ...
