Answer: (C) Radioactive dating</h2>
Explanation:
Let's begin by explaining that radioactive decay is a spontaneous process in which the nucleus of an atom disintegrates, giving way to the emission of radiation and the appearance of a new nucleus, releasing energy in the process.
<u>This process is widely used in</u><u> radioactive dating</u> (also called isotopic dating or radioisotope dating) in which radioactive impurities were selectively incorporated when the fossil materials were formed.
In this sense, when dating the age of the Earth and its components, it is useful to compare them with a naturally occurring radioisotope having a known half-life (generally uranium-238 is used and sometimes carbon-14).
This is reactivity. It describes how easily one substance reacts with another
<span>Young modulus E = stress/strain where E is the elastic modulus. We seek to calculate the the strain.
But we would have to get the stress first. Tensile stress = Force/Area. Force = 20100N. And the Area = 9.54* 13.9 = 132.606Nm^2.
Strain = stress/E.where E = 79. Hence we have 132.606/79 = 1.67</span>
Answer:
Temperature of parcel at 1000 ft is 85.5°F
Explanation:
Temperature of parcel at 0 ft =T₁ = 91.0°F
Dry adiabatic rate = 5.5°F/100 ft
Temperature of parcel at H₂ (1000 ft) = T₂ =?
Height of LCL = 5000 ft
As (1000<5000), so using the formula for parcel below or at the LCL i.e.
