7. In addition to time being relative, Einstein also determined distances are relative as well. Using the formula for length contraction, determine what the distance to this black hole appears to be from the Earth from the Veracious crew point of view. Is this the proper length or is it a contracted length

Asap and show ! a 14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.

Iron is a transition metal with multiple oxidation numbers. (answer the following) a. what is the iron (ii) ion? how does it differ from the iron (iii) ion? b. if iron were to bond with oxygen, predict the formula for each oxidation number of iron. c. how would each formula be named?

If anyonee has done the momentum lab practical in physics can you give me the answers i am s lostt rnn : (
