What is the temperature of a star whose maximum light is emitted at a wavelength of 290 nm?

The first law of thermodynamics states that heat added to a system is neither created nor destroyed but is as it changes into other forms of energy.

Two wooden members of 80 × 120-mm uniform rectangular cross section are joined by the simple glued scarf splice shown. knowing that β = 22° and that the maximum allowable stresses in the joint are, respectively, 400 kpa in tension (perpendicular to the splice) and 690 kpa in shear (parallel to the splice), determine the largest centric load p that can be applied using mohr's circle. (round the final answer to two decimal places.)

The chemical formula for carbonic acid, a compound used in carbonated drinks, is h2co3. assume that these symbols represent the three elements of this compound:
