A barrel of oil is exactly 42 gal. how many liters of oil are in a barrel

Physics

Natali [406]3 years ago
6 0
The conversion from gallons to liters is 1 = 3.785.

Keeping this in mind...

42 x 3.785 = 158.97 liters.

If rounding, there are about 159 liters of oil in a barrel.

Does cross transfer occur when fibers are transferred from the victim to the suspect
lesantik [10]
When two people come in contact or when contact occurs with an item from the crime scene, the possibility exists that a fiber transfer will take place. This does not mean that a fiber transfer will always take place. Certain types of fabric do not shed well (donor garments), and some fabrics do not hold fibers well (recipient garments). The construction and fiber composition of the fabric, the duration and force of contact, and the condition of the garment with regard to damage are important considerations.


Hope this helps.

What principles of science (like facts, laws, and theories) might help explain why similar investigations conducted in many part
natulia [17]

Answer:

Reproducibility of research

Explanation:

The principle of science that explains why similar experimental investigations conducted in different parts of the world could result in the same outcome is referred to as reproducibility.

<em>A good research or experiment in science must be reproducible, otherwise, the outcome of such an experiment might become inadmissible within the scientific community. It is a core principle of the scientific method that similar results should be obtained when an experiment or observational study conducted in one place is repeated in another place with the same procedure. Hence, an experiment must be reproducible in science in order for the outcome of such an experiment to be part of the general scientific knowledge. </em>

The potential energy between two atoms in a particular molecule has the form U(x) = 2.1 x 8 − 5.2 x4 where the units of x are le
a_sh-v [17]

Answer:

x\approx 0.948

Explanation:

The correct formula for the potential energy between two atoms in a particular molecule is:

U(x) = \frac{2.1}{x^{8}}-\frac{5.2}{x^{4}}

Where x is the distance.

According to the definitions of potential energy and work, as well as the Work-Energy Theorem and the Principle of Energy Conservation. The relation between that and related force is:

F = -\frac{dU}{dx}

The function is derived in terms of distance:

F (x) = \frac{84}{5\cdot x^{9}} -\frac{104}{5\cdot x^{5}}

Then, it is needed to find at least of x so that F(x) equals to 0.

\frac{84}{5\cdot x^{9}}-\frac{104}{5\cdot x^{5}}=0

\frac{84}{x^{4}}-104 = 0

84-104\cdot x^{4} = 0

x=\sqrt[4]{\frac{84}{104} }

x\approx 0.948
