How to make a simple pinhole camera?
We know the wooden bats are solid wood, so the aluminum bats must not be solid aluminumThe aluminum bat's core is either hollow or some other less dense materialFoam would be a good candidateIt would help absorb and dissipate the shock of contacting a 90mph baseball that an aluminum bat would otherwise do less well than a wooden bat.
Cover a window with aluminum foil, Put a small round hole in the foilMake the room darkHold a piece of white paper in front of the holeThe distance from the hole will determine the size of the picture.
Density is not about the size or mass of any particular object, but the weightFor example, oil is less dense than water, that's why oil floats on waterThe other example would be comparing helium airYou can fill 2 balloons with the same amount of the 2 gases helium being of smaller density than air will cause the balloon to rise.
im very sorry but you need to check that question with your teacher cuz i think it is wrongdensity mass x volume therfore it would be impossible for the two to the same density if they had same mass and volume the only way they could have the same density is if the volume or the mass of either varied egfor bat density mass X volume mass 56 volume 10 ther fore denisty 56 X 10 560 for aluminium bat density mass X volume mass 70 volume8 ther fore density 70 X 8 560
If we make two bats , aluminum and wood, we can make them if the same densityLike for example, we need to produce bat in a very thin material or make inside hollow and whateverAll the solution and option is on the aluminum batWooden bat is constant.
