Nicholas Copernicus, Greek astronomer, was the one who famously proposed the heliocentric theory -- the theory by which the sun was in the center of the solar system and the planets orbited it circularly.

Answer:
Spills out 10cm³ of wather.
Explanation:
The ball being submerged halfway in the full glass of water will spill a volume of water equal to the volume of the ball that is being submerged, because the entire volume of the submerged ball was previously occupied by water and is not compressed should move out of the glass.This volume will be 10cm³ since the total of the ball is 20cm³ and it is submerged halfway.
Answer:
Kinetic energy = 127.89 Joules
Explanation:
Kinetic energy is calculated using the following rule:
KE = (1/2)*v* v^2
Where:
m is the mass = 145 g = 0.145 kg
v is the velocity = 42 m/sec
Substitute in the above equation to get the kinetic energy as follows:
KE = (0.5)(0.145)(42)^2
Kinetic energy = 127.89 Joules
Hope this helps :)
