Question

If the boat and the cube have the same mass, which of these is true?

Answer 1

C. the boat is less dense than the cube, it has more of a surface to displace the water, giving it more buoyancy.

Answer 2

thank you do you think you could help with another?

Answer 3

sure

Answer 4

A. increasing its volume would make it bigger, but not heavier. like the boat.

Answer 5

ok thxs! im sooo sorry but i dont get these at all do u mind helping me with the others?

Answer 6

no prob, shoot.

Answer 7

ok one secc

Answer 8

science3= A. \[Density=\frac{ mass }{ volume }\] mass is weight and volume is size\[D=\frac{ 15g }{ 5.5cm ^{3}}\] so divide 15 by 5.5 which is 2.7. grams do not divide into centimeters cubed, so the unit will look like \[\frac{ g }{ cm ^{3} }\]

Answer 9

science4. B the weight must be less than the buoyant force for it to float. the buoyant force is what makes something float, so it must be greater than the weight, or the force pushing it down.

Answer 10

science5. A. the buoyant force decreases if it becomes heavier without becoming larger to equal the water displacement.

Answer 11

OMG thank you soo much!!

Answer 12

welcome :)
