Scientists were studying three different embryos to determine their relationship to humans. The notes about each embryo are show
n in the chart. Based on the information, what can you determine? Species A and B are related to humans. Species A and C are related to humans. Species B and C are not related to humans. Species A and C are not related to humans.
So at joints C and D do I let there be a Cx, Cy and Dx, Dy respectively or do I just keep it as Fwd and Fwc? Either way I can't seem to solve it. â‘Fx=0=WD-4293cos19.74 ÎŁFy=0=Fwc Sin19.74 - 1450 Fwc= 4203 lb WD = 4041 lb Then at joint C â‘Fx=0=CDsin30 - CAsin30 - 4041 â‘Fy=0=1450-CDcos30-CAcos30 CD = 4878 CA = -3204 Incorrect.
In order to calculate the amount of energy required, we must first check the latent heat of vaporization of water from literature. The latent heat of vaporization of any substance is the amount of energy required per unit mass to convert that substance from a solid to a liquid. For water this is 2,260 J/g. We now use the formula: Energy = mass * latent heat Q = 50 * 2,260 Q = 113,000 J
