The position of a particular particle as a function of time is given by r = 9.0t + 8.85– 1.00t^2  m. What is   the average velocity of the particle between t=1.00s and t=3.00s?Required to answer. Single choice. (2 Points)​

Acar travels along a highway with a velocity of 24 m/s, west. the car exits the highway; and 4.0 s later, its instantaneous velocity is 16 m/s, 45° north of west. what is the magnitude of the average acceleration of the car during the four-second interval?

The diagram shows a series of volcanic island and a hot spot determine the direction of movement of the tectonic plate that for the island

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
