a) What is the acceleration due to gravity on the surface of the M0011? Take the mass of the M0011 and its radius to be 7.348 X 1022 kg and 1.737 x 103 km, respectively. m/s2 b) On the surface of Mars? Take the mass of Mars and its radius to be 6.418 X 1023 kg and 3.390 X 103 km, respectively. m/S2 Astrology, that unlikely and vague pseudoscience, makes much of the position of the planets at the moment of one's birth. The only known force a planet exerts on Earth is gravitational. a) Calculate the magnitude of the gravitational force exerted on a 3.00 kg baby by a 84.0 kg father 0.200 m away at birth (he is assisting, so he is close to the child). N b) Calculate the magnitude of the force on the baby due to Jupiter if it is at its closest distance to Earth, some 6.29 x 1010 m away. Take to mass of Jupiter to be 1.898 x 10" kg. N c) How many times greater is the force exerted by the father on the baby compared to that exerted by Jupiter? Other objects in the room and the hospital building also exert similar gravitational forces. (Of course, there could be an unknown force acting, but scientists first need to be convinced that there is even an effect, much less that an unknown force causes it.)
