Athin, square metal plate measures 15 cm on each side and has emissivity of 0.80. the plate is heated to a temperature of 605°c. what is the rate at which the plate radiates energy? the stefan-boltzmann constant is 5.67 × 10-8 w/(m2 ∙ k4). remember that the plate will radiate energy from both its top and bottom surfaces. 1.2 kw 2.1 kw 980 w 900 w

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
