EXPLAIN WITH STEPS PLZ! * A boat moves towards the east with velocity of 20 m/s, then it is affected by acceleration towards the west of 4 m/s^2?, so its displacement after 15 s from the moment at which the boat starts to acquire the acceleration equals

a 350 m towards the east

b 300 m towards the west

c) 750 m towards the east

d) 150 m towards the west

F500 j of energy were added to 1 kg of each of these samples, which would experience the least temperature increase?

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.
