-find the mass of a copper block, density of 8.9 cm3, volume of 2 cm-find the volume of a aluminum bar, density of 2.7cm, mass -15g-find the density of metal bar, mass-23 g, volume-54 cm
I do Keystone and that i purely used Blondie's solutions and that i've got been given 3 of them incorrect and failed. So for whoever is the subsequent person that's in 8th Grade technological know-how and does Keystone and is taking Lesson 6: Fc- Lesson Quiz take my be conscious for it rather. THE solutions ARE: a million) A pineapple 2) The tension of gravity will improve with mass and reduces with distance. 3) it rather is greater tricky to start pushing an entire figuring out to purchase cart than it rather is to push it as quickly because it rather is already moving. 4) Air resistance and gravity. 5) In a vacuum do no longer make an identical MISTAKE I DID!!! sturdy luck TO 8th GRADE KEYSTONE pupils!
DensityMass/Volume The rest is simple algebra. You should be able to do it yourself.
Sounds like 8th grade physical science. Cu 17.8g Al 5.55cm3 bar.g/cm3
