The latent heat of vaporization of h2o at body temperature (37.0° c) is 2.42 106 j/kg. to cool the body of a 84 kg jogger (average specific heat capacity = 3500 j/(kg · c°)) by 1.2° c, how many kilograms of water in the form of sweat have to be evaporated?

When many atoms are split in a chain reaction, a large explosion occurs. this is an example of what type of energy conservation

Light from two different sources are incident upon the same side of a polarizing filter. light from one source is polarized with total intensity ip, while light from the other source is unpolarized with total intensity iu. as you rotate the polarizing filter through 360 degrees, the intensity of the transmitted light on the other side varies by a factor of 9. what is the relative intensity of the initial polarized source to the unpolarized source, or ip/iu?

Give me a example of a decomposer. explain what would happen if decomposers were absent from a forest ecosystem
