A) nucleus because some aims reflected off the gold foil proving that there was something bigger inside the atom hence discovering the nucleus
It will sink because mass does not affect the physical properties of the object.
Answer:
80m, assuming g=10m/s^2
Explanation:
40m/s will be reduced to 0m/s in 4 seconds. 4 seconds x 40m/s would be 160m up, but you will only get half of that because you decelerate linearly to 0m/s. This leaves you with 4 x 20 = 80m.
