Awooden block of mass m resting on a frictionless, horizontal surface is attached to a rigid rod of length script l and of negligible mass. the rod is pivoted at the other end. a bullet of mass m traveling parallel to the horizontal surface and perpendicular to the rod with speed v hits the block and becomes embedded in it.
(a) what is the angular momentum of the bullet–block system about a vertical axis through the pivot? (use any variable or symbol stated above as necessary.) l=
(b) what fraction of the original kinetic energy of the bullet is converted into internal energy in the system during the collision? (use any variable or symbol stated above as necessary.)

You notice a very one-dimensional-thinking snail crawling along one rail of a railroad track. naturally, you remove it to a safer place. but before you do, you observe it as it moves from position xi = -92.9 cm to position xf = -64.9 cm along the rail, as measured from a point where one rail abuts the next. what is the snail\'s displacement δx in centimeters?

Which of these statements best explains how the hydrosphere interacts with the atmosphere to affect global climate? mountains block rain clouds and cause changes in global rainfall and evaporation. humans burn fossil fuels to produce greenhouse gases which cause global warming. humans cut down trees which affects the amount of oxygen in different parts of the globe. greenhouse gases, like carbon dioxide, dissolve in oceans and prevent global warming.
