Asmall, metallic, solid cyllinder made of gold, has a radius of 2.00mm and a length of 3.00cm. the number of free electrons in each atom of gold is le (electrons in the conducting band.) the density of gold is 8.96 %㎡ and the molar mass of gold is 63.55 %01. use scientific notation for all of your answers. (1) (10 points) find the volume and the mass of the cyllinder, in s. i. units. (ii) (10 points) find the number of moles of gold and the number of gold atoms in the cyllinder. (iii) (10 points) find the maximum electric charge this material could have, if all the conduction electrons were to be removed, in s. i. units.

We want to calculate the total metabolic heat generated by a singing canary taking into account heat transfer by radiation, convection and exhaling air. the air temperature is 20 oc, canary’s body internal and surface temperature is 33oc, external body surface convective heat transfer coefficient is 25.2 w/m2 .k, temperature difference between the inhaled and exhaled air is 4.3 oc, the ventilation rate is 0.74 cc of air per second, specific heat of air is 1.0066 kj/kg.k and density of air is 1.16 kg/m3 . assume the canary’s body to be a cylinder with 7 cm diameter and 9 cm length, and heat exchange is from the side as well as the top and bottom of cylinder. calculate 1) the net rate of heat lost by radiation, assuming heat gained by the bird through radiation from the surroundings is 11.5 w; 2) rate of heat transferred by convection to the surrounding air; 3) rate of heat transferred in the exhaling air without considering any internal evaporation; 4) total metabolic power.

Starting with only the balmer series light (visible light), how could we ensure that the solar panels generate a current that mark can use for his power station? a)by gradually increasing the brightness (amount) of light that we shine on it. b)by gradually increasing the frequency of the light we shine on it. c)by gradually increasing the wavelength of the light that we shine on it.
