less dense
I can't see the specific ball you're dealing with. If it sinks in water, then it's more dense than water. If it floats on water, then it's less dense than water.
1.2 x 10^4 J That is in Significant Figures
no
The snowball is less dense since it's lighter and the golfball is more denser, but in water the snowball will melt back into it's original state.
You get a soccer ball pump needle a stick it into a balloon and it will inflate

Freeze it.
No. If the density of the item is less, the mass may be less, even if the object is larger. Cannon ball and a beach ball. Low density beach ball has far less mass than the VERY dense cannon ball, even though the beach ball is larger.
That depends on what is it made of, however even lead cannon ball would float in mercury, let alone steel one. If you compare densities, you can see that mercury is more dense than lead in room temperature (13530 kg m-3 vs 11 540 kg m-3). One can imagine a cannon ball made of depleted uranium perhaps, which would sink in mercury, being more dense.
for at home it is.... 1. drop the red ball in the upper left Conner into the cannon 2.then drop the green ball into the small cannon on the train track 3. drop the bar that is stopping the train track 4.next drop the pink string of the red ball so it will swing then drop the last string so it will fall into the cannon 5. the green ball (not connected to the balloon) should be swinging now just drop it into the box 6. drop the final green ball into the cannon
A cannon ball.
a cannon ball
a steel ball bearing will drop faster in warm water then cold water, a beach ball will float better in cold water because cold water is more dense.
the size of the cannon ball depends on the size of the cannon. civil war cannons had cannon balls about the size of a child's head, aprox 30cm across
cannon ball
Yes, both have the same energy, but because cannon is heavier the cannon ball gets more momentum and thus greater velocity.
1) Drop the green ball that's all the way to the right into the cannon by cutting the red string and letting it swing to the left and then cutting the green string. Drop it in the cannon, not the green box. 2) This will trigger the cannon and hit the green ball carried by the yellow gold balloon and will move that green ball all the way to the left. 3) Drop the red ball that's all the way to the left into the cannon by cutting the green string. 4) Cut the string holding up the train so the train moves towards the left. 5) Drop the red ball in the middle by cutting the purple string first, and then dropping it into the red box, by cutting the green string. 6) This will hit the green ball hanging in the middle. Cut the purple string to drop it in the box. 7) Drop the green ball hanging from the balloon into the cannon by cutting the red string and wait for it to swing to the right and then cut the remaining string to drop it into the box.
