Without artificial gravity, human growth is stunted and biological functions break down. An effective way to create artificial gravity is through the use of a rotating enclosed cylinder, as shown in the figure. Humans walk on the inside edge of the cylinder, which is sufficiently large (radius R) that its curvature is not readily 2R- noticeable to the inhabitants. The space station in the figure is not drawn to scale. Once the space station is rotating at the necessary speed to create an artificial gravitational acceleration equal to the acceleration g at Earth's surface, how long will it take the space station to make one revolution? Express this time t in terms of g and R. t = !!

5. Two masses m1 = 350 kg and m2 = 350 kg are at a distance of 22  m from each other. Find the magnitude and direction of the gravitational field at a point A. Data: h = 9m, G = 6.674 x 10-11 N•m2/kg2     Comments: Thank you for helping me ♡

14.) A hypothetical planet has a radius 2.1 times that of Earth, but has the same mass. What is the acceleration due to gravity near its surface? Express your answer to two significant figures and include the appropriate units. gplanet= ____________ ______________   15.) A 1400-NN crate rests on the floor. a.)

orbit of Jupiter orbit of Earth Hohmann ellipse NASA would send a satellite to the planet Jupiter. To use the least fuel, the satellite would travel on a "Hohmann ellipse" with perihelion at TE and aphelion at rj - as shown in the figure; the semimajor axis is a=(re+rJ)/2. How many days would it take the satellite to travel from Earth to Jupiter? DATA: TE = 1 AU ; rj = 5.2 AU ; The astronomical unit (AU) is a unit of length relevant to the Solar System. 1 AU = the mean distance from the sun to Earth. 1 AU = 1.496 × 10¹¹ meters. {time to go from Earth to Jupiter =} (in day) A: 996.8 OB: 1445.3 OC: 2095.7 OD: 3038.8 OE: 4406.3 OF: 6389.1 OG: 9264.3 OH: 13433.2
