Q: Why am I so cool?
A: I have no clue lol :)
Could you please mark this answer as brainiest?
It would help me a lot!
Thank you!
The only option that fits is the last one — improper and biased measurements.
A scientist should be able to estimate a measurement to a tenth of the smallest scale division. The millimetre ruler would give an uncertainty of ±0.1 mm. The inch ruler would give an uncertainty of ±0.1 in. Since 1 in = 25.4 mm, 0.1 in = 2.54 mm. Thus, the <em>millimetre ruler is more precise</em> than the inch ruler.
Converting units <em>does not</em> change the degree of precision of a measurement.
The first scientist <em>did not</em> convert the units (the second scientist did!).
BUT, having different team members make the observations could introduce uncertainties caused by improper or biased readings of the equipment.
The scientists produced an adhesive that was made from carbon nano tubes. The adhesive has two different layers; the lower layer is composed of vertically aligned nano tubes while the upper layer is made up of curly nano tubes that are spaghetti - like in shape.
The adhesive device produced can hold a maximum force of 700 pounds while adhering to a smooth surface.<span />
Answer:
35g/l
Explanation:
Salinity is practically the saltiness of the water, in basic terms. It's basically the amount of salt dissolved in water. Ocean water has a salinity of around 35g/l (that's about 3.5% of which is dissolved salt in water!). However, Atlantic Ocean (the ocean with the saltiest water), can range up to 37g/l.
