To move herself toward the space station she could, a) throw the wrench directly toward the station, b) throw the wrench parallel to the orbit of the station, c) throw the wrench away from the station or d) throw the wrench toward the space station without letting go of it.arrow_forwardA satellite orbiting Earth is repositioned so that it is twice as far away from the Earth's center of mass than it was before. How does the force of gravity on the satellite change in this situation? The force of gravity is multiplied by 4 The force of gravity is multiplied by 1/2 The force of gravity doesn't change The force of gravity is multiplied by 2 The force of gravity is multiplied by 1/4arrow_forwardIsaac Newton looks up at an apple. He is on planet earth and starts to think... which of his thoughts are true? (a) The force on the Earth is greater than the apple- because the Earth is more massive. (b) The force on the apple and the Earth are 0 because they aren't touching. (c) The force on the apple is greater than the Earth- because the Earth is more massive. (d) The force on the apple and the Earth are equal.arrow_forward

The only known force a planet exerts on Earth is gravitational. (a) Calculate the magnitude of the gravitational force exerted on a 3.70-kg baby by a 100-kg father 0.221 m away at birth (assisting so he is close). N(b) Calculate the magnitude of the force on the baby due to Jupiter if it is at its closest to the Earth, some 6.29 1011 m away, showing it to be comparable to that of the father. The mass of Jupiter is about 1.90 1027 kg. 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.) Narrow_forward
