Aball moves along a 1d coordinate system with the following motion parameters at time t-o s: 7.7 m and vo- 2.5 m/s. the ball has a constant acceleration of 2.7 m/s2 during the entire motion which occurs over a time of 2.1 s. assume that an error in position of 5 % is acceptable in this application over the entire motion. how many rows n will be needed in the table to model the enti motion to within the required error even though you are leaving out the final term of 1/2 a (at) present in the exact position expression?

What color of light must blue light mix with to create white light? a. yellow b. white c. blue d. green

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.

What equation is used to calculate the weight of an object on a plant ?
