Water has a density of 1.0 g/cm3. which of the following objects will float?
density of object will it float? yes or no
a. ice = 0.92g/cm3
b. wood = 0.45 g/cm3
c. bone = 1.7 g/cm3

Hello!! Being so that if a substance has greater density, it will sink, then if it has less density it will float! Ice and Wood will both float because the density in the substances are less than the density in the water. The Bone will sink because the density is .7 g/cm3 over the amount of density the water can hold! Hope this helps :)

what are the statements? x

russian is not my first language, so i'm afraid i can't write out an answer in russian, but hopefully you can find a way to do so. here's my best translation of the problem: you're given a plot of a particle's position in one-dimensional space over time, and you're asked to find either the total distance traveled by the particle after 6 seconds had elapsed, or the total displacement of the particle after 6 seconds.

if you want the total distance traveled, you would first need to determine the particle's velocity as a function of time, then integrate that over the 6-second interval. we know the position function is quadratic with roots at 0 and 6, so we have

where is unknown. because the position is parabolic, there is symmetry about the midpoint at , and we know that

so that the position function is

which means the velocity is

then the total distance traveled is

so the total distance traveled is 20 m.

on the other hand, if you want to find displacement: the particle starts at and ends at , so its displacement is 0.
