An aluminum road of each side 4cm is subjected to a tangential force. The top of
the cube is sheared0.012cm w. r.t. the
bottom. Find (i) shearing strain (ii) shear
stress and (in) shearing force. Given that
modulus of rigidity is 2.08x1010 N/m?

Which two particles are found in the center of an atom

The diagram shows four locations in the electric field of a positive point charge m. at which location is the electric potential the greatest.

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i.e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i.e. include the distance traveled to the first encounter)
