A surface wave is a wave in which particles of the medium undergo a circular motion.
Answer:
D.90°
Explanation:
First remember that the magnitude of a vector , lets say T is the square of the dot product with itself.
This is to say
|T|=√(T×T)
Assume A≠0 and B≠0 then
Square both sides of the below equation
|A+B|²=|A-B|²
(A+B)²=(A-B)²
A(A+B)+B(A+B)=A(A-B)-B(A-B)
A²+AB+AB+B²=A²-AB-AB+B²
A²+2AB+B²=A²-2AB+B²
You notice that it simplifies to
2AB= -2AB
This means that A×B =0
Hence the angle between the vectors should be 90°
An object or any location can be represented on a two-dimensional surface like a paper or computer screen. This representation is known as map. Most maps do not take into account the elevation of the object or the location they representing. On the other hand, Topographic maps use contour lines to represent the third dimension and to show elevation change on or below the surface of the earth.
The correct option is
a. Acetyl-CoA combines with a pyruvic acid to make glucose in the Krebs cycle.
Explanation:
The Krebs citric acid cycle happens within the mitochondrial matrix and generates a pool of energy (ATP, NADH, and FADH2) from the oxidization of pyruvate, the tip product of metabolism. Pyruvate is transported into the mitochondria and loses dioxide to make acetyl-CoA, a 2-carbon molecule.
