Q2:c) 19km per second.

Q3:c) The escape velocity of the target planet or moon-The velocity of the astroid has to be more than the escape velocity of the planet to enter its atmosphere.

Q4: b) Impact craters:The idea of plate tectonic was not discovered at that time.

Q5:b) Ejecta layers were overturned-Other three options are unique identification mark of an impact crater.
