Labels:text | screenshot | font | document OCR: b. It has been observed that the equatorial region of the solar atmosphere rotates at a rate of C = 2.94 x 1076 radians per second with respect to the distant stars. This is known as the thered/ wmaw mt and is equivalent to a sidereal rotation period of 2IT 2.94 x 10-6 3 = 2.14 x 10º s = 24.7 days. Spacecraft measurements of the solar wind velocity show time variations, with velocity peaks at approximately 25-day intervals as well. For example, Muziek measured velocities varying from 400 km's to about 750 km/'s at some peaks. Determine k and plot the graphs of the Archimedean spirals for velocities of 400 km/s and 750 km/s. (See next card for solution.)
