The amount of heat per second conducted from the blood capillaries beneath the skin to the surface is 240 j/s. the energy is transferred a distance of 2.0 x 10^-3 m through a body whose surface area is 1.6 m^2. assuming that the thermal conductivity is that of body fat (k = 0.20 j/(s•m•degrees determine the temperature difference between the capillaries and the surface of the skin :

a. 9.2 degrees c

b. 5.4 degrees c

c. 1.5 degrees c

d. 6.9 degrees c

e. 3.7 degrees c

A10.0 kg cart and a 15kg cart are locked together with a compressed spring between them. they are then released so that the spring pushes the two carts apart. the 10.0 kg cart is moving at 4.5 m/s afterward. how fast is the 15kg cart moving? 3.0 m/s 2.0 m/s 4.5 m/s 5.0 m/s

Calculate the ratio of h+ ions to oh– ions at a ph = 6. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1
