Aluminum has a density of 2.70 gm/cm cubed. what is the mass of a peice of alluminum that has a volume of 100.00 cm cubed

density=2.70

volume=100

mass=density*volume

so,

2.7*100=270

mass is 270gram

270 g

Explanation:

The density of a substance tells you the mass of exactly one unit of volume of said substance.

100cm^3 x 2.70g/ 1cm^3= 270 g

anchor = archer //

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
