Speciation is how new organisms arise. The fossil record's name is self-explanatory: a record of the fossil found. Natural selection is when traits that are better for survival are passed down to the next generation. Therefore, C) radiometric dating is the answer.
Given:
P1 = 400 kPa
T1 = 110 K
T2 = 235K
Required:
P2
Solution:
Apply Gay-Lussac’s
law where P/T = constant
P1/T1 = P2/T2
P2 = T2P1/T1
P2 = (235K)(400kPa)
/ (110K)
P2 = 855 kPa
Give me some answer choices and i will be happy to help
<h2><u>Q</u><u>u</u><u>e</u><u>s</u><u>t</u><u>i</u><u>o</u><u>n</u>:-</h2>
The speed of a wave is 40 m/s. If the wavelength is 80 centimeters, what is the frequency of the wave ?
<h2><u>A</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u>:-</h2>
<h3>Given:-</h3>
Velocity (V) = 40 m/s
Wavelength
= 80 cm = 0.8 m
<h3>To Find:-</h3>
The frequency (F) of the wave.
<h2>Solution:-</h2>
We know,

40 = F × 0.8
F = 
F = 50
<h3>The frequency of the wave is <u>5</u><u>0</u><u> </u><u>H</u><u>z</u>. [Answer]</h3>
Answer:
Option C is correct.
The magnitude of the field is reduced to half at twice the distance,
Explanation:
The magnetic field produced in a long, straight conductor carrying a current I at distance r is given by
B = μ₀I/2πr
Where μ₀ is the constant permeability of free space.
If we increase the distance by twice then
B = μ₀I/2π(2r)
B = μ₀I/2πr(2)
B = B/2
Therefore, the magnitude of magnetic field is reduced by B/2 at twice the distance.
