- Sirius B is a white star that has a surface temperature (in kelvins) that is four times that of our sun. Sirius B radiates only 0.040 times the power radiated by the sun. Our sun has a radius of 6.96 × 108 m. Assuming that Sirius B has the same emissivity as the sun, find the radius of Sirius B. RSB= O52. Assuming the +x-axis is horizontal to the right for the vectors given in the following figure, use the analytical method to find the following resultants: (a) 11.671+ 8.991. (b) 9.011-6.401.

- Charlie wants to know the mass of his copper statue of Isaac Newton, but he doesn't have a scale. So, he heats up the statue to 97.0° C and plunges it into a tank of cold water (50 kg) at a temperature of 6.00° C. He notices that the water temperature rises to 9.00° C. What must be the mass of the statue? (Ignore the heat absorption of the water tank.) Specific heat of water: cwater = 4186 J/kg-°C Specific heat of copper: copper = 387 J/kg-°CHow to find the number of atoms in an iron cylinder given its mass(g)?
