A thermal tap used in certain apparatus consists of a silica rod which fits tightly inside an Aluminium tube whose internal diameter is 8 mm at 0℃ . When the temperature is raised, the fit is no longer exact. Calculate what change in temperature is necessary to produce a channel whose cross-section is equal to that of a tube of 1 mm internal diameter. Α for silica = 8 × 10 − K − 1 , α for Aluminium = 26 × 10 − K − 1

the bald eagle got 50 because everything gets 10% of what they consume and since 50 is ten % of 500 hundred that means the   grasshopper had to have consumed a plant with 5,000 calories of energy

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.
