Determine the resultant velocity in the following case: A boat's engine can give it a velocity of 25m/s. If the boat heads due east across a river which is flowing due south with a velocity of 8.5m/s; what is the resultant velocity of the boat? (Remember you must find both a magnitude and a direction.)

Which of the following is considered to be a vector?               a.  temperature    b.  velocity    c.  time    d.  mass

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.

Arope has one end tied to a vertical support. you hold the other end so that the rope is horizontal. if you move the end of the rope back and forth with a frequency of 4 hz, the transverse wave you produce has a wavelength of 0.5 m. what is the speed of the wave in the rope?
