An object is thrown straight up with a velocity of 19 m/s on a flat level surface. If it takes 3.25 seconds to reach the peak of its arc, what will be the total time it is in the air

Groups of organs that work together to complete a process in the body are called: a. cells b. tissues c. nerves d. systems

How does an observation about an object differ from an inference about that object
