A marble is launched from the floor at a speed of 3.0 m/s at an angle of 15 degrees above the horizontal. How far away from the starting point will the marble land? (Assume a level floor and no friction.)

The particles of an ice cube at 0°c (represented by the blue circles) come in contact with the particles of juan’s hand at 37°c (represented by the orange circles). which diagram correctly represents the temperature of the two substances and the direction of heat flow?

What is the acceleration of a spaceship that is initially at rest and then speeds up to 220 m/s in 20 seconds

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat
