Ascientist used a laboratory model to test the effect of radiation, or the sun, in heating land and water on earth. to do this experiment, 200 ml of water and dry sand were placed in to 2 separate 250-ml beakers. each beaker was then placed under the same lamp. temperature readings were taken of each substance every 2 minutes for 8 minutes. use the data table to answer the following questions. substance heated starting temp (°c) 2 min 4 min 6 min 8 min water 18 18.5 19.5 21 22 dry sand 18 20 22 24 26 is this a controlled experiment? explain.

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 11.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.80 m/s; (b) he is then lifted at the constant speed of 4.80 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 78.0 kg rescue by the force lifting him during each stage
