Ascientist is creating a new synthetic material. the material’s density is 6.1 g/cm3. which sentences describe how the scientist can lower the material’s density? the scientist can decrease the mass while keeping the volume constant. the scientist can increase the mass while keeping the volume constant. the scientist can decrease the volume while keeping the mass constant. the scientist can increase the volume while keeping the mass constant.

The density is the relation mass/volume.

Then you can modifiy the density of a material by either affecting the mass or the volume.

If you increase the volumen while keeping the mass constant, the density will decrease (because you are increasing the denominator of the fraction).

Also, you can decrease the mass while keeping the volume constant to decrease the density (because you are decreasing the numerator of the fraction).

Then the answer is decrease the mass or increase the volume, while the other is kept constant.

hope this helps

Less force and energy was applied

Iread this book last year so take this with a grain of salt.gene jumps from the tree to compete with finny due to the fact that gene is always trying to do better than finny. he is put under the grasp of peer pressure due to finny almost forcing him to do this. ever since he first jumped finny kept pressuring him to jump since he thought gene enjoyed jumping.rather than uses this answer you should probably just reread chapters 3-4
