The 500-gram rock causes the larger splash because it has more kinetic energy. (I took the test and that was the answer you're welcome)
IU iS QuEEN is correct I took the quick check
All hail the Queen lol
tysm I needed to check my answer.
For example if the 350 gram rock is a flat plate and the 500 g rock is spherical, the smaller rock will make the larger splash.
On your questions you are giving the best answer you think is correct. I think you should give the choices available for the answer. Why? Because sometimes two answers can be very close to a nuance here or there makes a difference. It helps us if we have all of the choices from which to choose.
