Students conducting an analysis of an unknown substance repeatedly missed the mark. To identify the unknown, they calculated the density of their mystery element or compound. To do this, they recorded both the volume and mass of their sample.
All BUT one factor are unavoidable errors that could influence their results. That is
A)
calculator error.
B)
miscalibrated balance
C)
miscalculating the density.
D)
mislabelled samples provided by instructor.

An astronaut in space cannot use a scale or balance to weigh objects because there is no gravity. but she does have devices to measure distance and time accurately. she knows her own mass is 77.4 kg , but she is unsure of the mass of a large gas canister in the airless rocket. when this canister is approaching her at 3.50 m/s , she pushes against it, which slows it down to 1.30 m/s (but does not reverse it) and gives her a speed of 2.60 m/s . what is the mass of the canister?

Did anyone do 1.06 lab: cloud formation i need with it i go to k12 lavcame i need to get it done quick
