A hurricane passes over Miami. The eye of the hurricane travels with a speed of 50km/h in the direction 20 degrees west of north, 2 hrs later the winds shift and the eye of the hurricane has a speed of 40km/h and it travels in the direction 10 degrees east of north. After passing over Miami, where is the eye of the hurricane located after 3hrs relative to Miami.

Explain why the aperture of the spherical mirror should be small compared to the radius of curvature of the mirror.

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
