It takes much longer to cook food in the hills than in the plains, because
Options: in the hills the atmospheric pressure is lower than that in the plains and therefore water boils at a temperature lower than 100oC causing an increase in cooking time, due to low atmospheric pressure on the hills, the water boils at a temperature higher than 100oC and therefore water takes longer to boil, in the hills the atmospheric density is low and therefore a lot of heat is lost to the atmosphere, in the hills the humidity is high and therefore a lot of heat is absorbed by the atmosphere leaving very little heat for cooking
Why is the width of the data bus so important to the processing speed of a computer?
Options: The narrower it is, the greater the computer's processing speed, The wider it is, the more data that can fit into main memory, The wider it is, the greater the computer's processing speed, The wider it is, the slower the computer's processing speed
