Its mass remains the same but its new radius is 1.0 x 101 m. What is the new period of Scratt's orbit of constant radius? c) As ever the question is "Will Scratt get back his acorn?" The collapsed neutron star rotates at a rate of 300 times PER SECOND! Is gravity alone able to keep the acorn on the surface at the equator, or will it reunite with Scratt?

QUESTION 1 Estimate The Temperature For A Planet In Other Solar System (Questions 1-3) Let us assume scientists just discovered a planet orbiting a star in an extra-solar system. The star has a surface temperature Ts = 10000 Kelvins and a radius Sr = 1x109 meters. Scientists also measured the distance (D) between the star and the planet as D = 2 AU - 3.0x1011 meters. The solar power per unit area from the star's surface (Ps) can be calculated from the star's surface temperature Ts (10000 Kelvins) by the Stefen-Boltzman law Ps=0(Ts)4, where o is Stefen-Boltzman constant (5.67 x 10-8 Watt/meter2/Kelvin4). What is the solar power per unit area from the star's surface (Ps)? O Ps ~ 2.87 x 108 Watt/meter2 O Ps ~ 5.67 x 108 Watt/meter2 O O Ps ~ 2.87 x 10 Watt/meter2 Watt/meter² Ps ~ 5.67 x 10⁹ QUESTION 2 The solar power (Ps) decreases from the star's surface to the distance at the planet. Assuming the solar power per unit area at the distance of the planet as Pp, we have Pp=Ps(Sr/D)2, where…

During their physics field trip to the amusement park, Tyler and Maria took a rider on the Whirligig. The Whirligig ride consists of long swings that spin in a circle at relatively high speeds. Image source: https://dribbble.com/shots/9444643-Pink-carouse! As part of their lab, Tyler and Maria estimate that the riders travel through a circle with a radius of 5.1 m and make one turn every 5.3 seconds. The speed of the riders on the Whirligig is v = 27r m/s.

Jupiter's moon Io has active volcanoes (in fact, it is the most volcanically active body in the solar system) that eject material as high as 500 kmkm (or even higher) above the surface. Io has a mass of 8.93×1022kg8.93×1022kg and a radius of 1821 kmkm. Part A How high would this material go on earth if it were ejected with the same speed as on Io? (RERE = 6370 kmkm, mE=5.96×1024kgmE=5.96×1024kg) Express your answer with the appropriate units.
