Two mississippi companies, howard industries and kuhlman electric company, are responsible for most of the transformers and power grids produced in the united states and shipped world-wide.

what role does a transformer play in the supply of electricity over long distances?
a) transformers decrease voltage so electrical energy can safely be transmitted over long distances through wires.
b) transformers increase voltage before transmitting electrical energy economically over long distances through wires.
c) transformers decrease voltage before transmitting electrical energy economically over long distances through wires.
d) transformers convert nuclear energy to electrical energy before transmitting electrical energy economically over long distances through wires.

Aman tries to push a box of mass 4 kg with a force of 5 n but the box remains stationary if the coefficient of static friction is 0.45, what is the value of the maximum force of friction?

Acar moves at 12m/s and coasts up a hill with a uniform acceleration of -1.6m/s2. how far has it traveled after 6.0s?

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)
