Calculate the density of the baseball. Use the formula D = m/V
where D is the density, m is the mass, and V is the volume.

Determine whether the density of baseball is within the legitimate range for an official baseball.

Record your answers in Table C of your Student Guide.

What is the density of the baseball?

g/cm3

The acceptable density range of official baseballs is between 0.70 g/cm3 and 0.80 g/cm3. Is the questionable ball in this range of acceptable density?

insects!

explanation:

talk back to him about the sport and show him your expertise or leave the room

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.

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.
