If the air temperature is the same as the temperature of your skin (about 30 ∘c), your body cannot get rid of heat by transferring it to the air. in that case, it gets rid of the heat by evaporating water (sweat). during bicycling, a typical 72.0 kgperson’s body produces energy at a rate of about 501 w due to metabolism, 78.0 % of which is converted to heat. [recall that the normal internal body temperature is 98.6 ∘f and the specific heat capacity of the body is 3480 j/(kg⋅∘c) .]part aby how much would the body temperature of the bicyclist increase in an hour if he were unable to get rid of the excess heat? δt = ∘c submitmy answersgive uppart bfind out, how high a fever would it be equivalent to, in ∘f? t = ∘f submitmy answersgive uppart cis this temperature increase large enough to be serious? choose yes/no

Suppose you have three polarizing filters, with the second at an angle of 42∘ to the first and the third at an angle of 90∘ to the first. by what perfect will the original intensity of unpolarized light be reduced to after passing through all three filters?

Uranium has two naturally occurring isotopes. 238u has a natural abundance of 99.3% and 235u has an abundance of 0.7%. it is the rarer 235u that is needed for nuclear reactors. the isotopes are separated by forming uranium hexafluoride uf6, which is a gas, then allowing it to diffuse through a series of porous membranes. 235uf6 has a slightly larger rms speed than 238uf6 and diffuses slightly faster. many repetitions of this procedure gradually separate the two isotopes. what is the ratio of the rms speed of 235uf6 to that of 238uf6? express your answer to five significant figures.
