Why is thermal energy from the sun transferred to earth through electromagnetic waves instead of any other type of thermal energy transfer? electromagnetic waves can carry energy through matter. electromagnetic waves can travel through empty space. electromagnetic waves can move through gases faster than other types of energy transfer. electromagnetic waves can move more energy than other types of energy transfer.

Ben (55kg) is standing on very slippery ice when junior (25kg) bumps into him. junior was moving at a speed of 8 m/s before the collision and ben and junior embrace after the collision. find the speed of ben and junior as they move across the ice after the collision. give the answer in m/s. describe the work you did to get the answer.

Consider a file currently consisting of 200 blocks. assume that the file control block (and the index block in the case of indexed allocation) is already in memory. calculate how many disk i/o operations are required for contiguous, linked, and indexed (single-level) allocation strategies, for each of the conditions listed below. in the contiguous-allocation case, assume that there is not room to grow at the beginning but there is room to grow at the end. also assume that the block information to be added is stored in memory.

Area around a charged object where the objects can exert a force on another charged objects is an electric
