The first one because the slope is 2/1 and y-intercept is -4
10% of 320 = 32
So 9.8% of 320 should be some number between 31 and 32
The surface of a spherical conductor of radius a is kept at a temperature of u(φ)=300K+50K cos(φ). The temperature inside is governed by the Laplace equation. Find an expression for the temperature everywhere inside the sphere. Evaluate the temperature at the center of the sphere.
