Answer 1

Q1. c

Q2. b

Answer 2

around action in a gravity field (it quite is, a around orbit) happens because of the fact the gravitational stress continuously pulls in direction of the physique it quite is being orbited. this suggests that if an merchandise strikes previous the physique, the stress is directed perpendicularly to the action. This differences the direction of the action, in direction of the physique, however the sideways action isn't eradicated. At *each and every* factor of the action, the stress is directed right this moment downward, so it incredibly is often performing at maximum appropriate angles to the action. because of the fact the stress acts in the comparable way in any respect factors (continuously in direction of the midsection), it continuously impacts the action the comparable way. the direction of a few thing it quite is consistently affected in this style of way -- equivalent effect in any respect factors -- is a circle. learn the diagram I made, showing the effect on the direction of action of an merchandise passing a gravitating physique (including a planet). The stress is shown consistently changing the direction of the action. (besides the reality that I had to charm to it in a corpulent vogue -- the orbiting merchandise does not actual pass in a right this moment line for a together as, then get redirected, then pass right this moment, then get redirected; it incredibly is a delicate, non-supply up technique.)
