Consider a vector in two dimensional space:
\overrightarrow{v} = \widehat{i}
starting at r = 1, \theta = 0, and moving around the unit circle with constant r = 1, but varying \theta. the assumption is that the vector itself should not vary (i. e. the semicolon derivatives should be zero around the curve).
write (and solve if possible) a differential equation describing the changes in the components of \overrightarrow{v} as you parallel-transport it around the unit circle.

An ambulance emits a frequency of 450 hz from its siren. what frequency is heard by a man as the ambulance moves toward him? less than 450 hz more than 450 hz 450 hz 0 hz

To create electromagnetic induction, which of the following has to move? a. a wire b. a magnet c. a transformer d. either a or b

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
