Have you ever wanted to be an inventor? now is your chance! for this portion of the assessment you will design your own rube goldberg device. rube goldberg devices use simple everyday items and take advantage of simple potential to kinetic energy conversions. when several of these conversions are combined, the device is able to perform a simple task, just like the one in the lab activity.

If a refrigerator is a heat pump that follows the first law of thermodynamics, how much heat was removed from food inside of the refrigerator if it released 380j of energy to the room?

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
