Atransverse sinusoidal wave on a string is moving in the −x-direction. its speed is 30.0 m/s, and its period is 16.0 ms. at t = 0, a colored mark on the string at x = 0 has a vertical position of 2.00 cm and is moving down with a speed of 1.50 m/s.(a)
(a) what is the amplitude of the wave?

(b) what is the initial phase angle?

(c) what is the maximum transverse speed of an element of the string?

(d) write the wave equation for the wave.

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

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.
