A54.1 kg box is held in place at the top of an 32.9 degree incline by a rope that is parallel to the surface of the incline. the box is then lowered down the incline at 0.459m/s^2, coefficient between incline and box is 0.209, what is the tension supplied by the rope?

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?
