As a science fair project, you want to launch an 850 g model rocket straight up and hit a horizontally moving target as it passes 31.0 m above the launch point. The rocket engine provides a constant thrust of 17.6 N. The target is approaching at a speed of 16.0 m/s.

At what horizontal distance between the target and the rocket should you launch?

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)

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 !

What is the moment of inertia i of this assembly about the axis through which it is pivoted? express the moment of inertia in terms of mr
