they must be correct and they must be the right kind of sample
Depending on the lens choice, the lens may need to be very close to the sample to focus. This is especially true with the higher magnifications.You don't want to smash the lens into your sample, damaging the sample and the lens.
Again another of my homework questions and i think its control
Yes it is true
if a is true, then b must be true
It must be possible to observe whether the hypothesis is true.
they must be correct and they must be the right kind of sample
False
true
For radioactive dating to be possible, the sample must contain a measurable amount of a radioactive isotope with a known decay rate. The sample must be isolated from sources of contamination that could affect the accuracy of the dating. Additionally, the sample must have remained a closed system since the radioactive isotopes were incorporated, in order to accurately measure the decay products.
Your intention is to transfer only the true sample into the conical flask, not the dirt from the scoop.
The pressure must have been extremely low in the container.
The pressure must have been extremely low in the container.
If that is true then some of them must be unbelievably boring!
The sample must contain Uranium-235.
A sample is a part of a population
The best true sample of the true members of different stars consists of
If a proportional relationship is graphed on the coordinate plane, what things must be true?
