Answer:
Sella Turcica
Explanation:
The sella turcica (also called the hypophyseal fossa or pituitary fossa) is a mid-line saddle-shaped depression in the sphenoid bone and belongs to the middle cranial fossa and it can be located by centering the CR (central ray) at a point 3/4" anterior and 3/4" superior to the E.A.M. (external auditory meatus).
Answer:
63.36 kJ
Explanation:
Potential energy (PE) is the energy stored within an object, due to the object's position, arrangement or state.
Since the Boulder is now on a height , it has a potential energy
<em>Potential Energy = mass * gravitational acceleration * height</em>
(Assume the gravitational acceleration = 10ms⁻²)
You would observe an absorption line spectrum.
I would say the number of harmonics decrease, because you're adding to the frequency of a wave.
I hope this helps :)
The correct option is B.
There are four basic factors which affect the properties of stringed instruments, these are frequency, diameter [thickness], tension and density.
Diameter refers to the thickness of the string. Thick strings with large diameter vibrate slower and thus they have lower frequency and lower pitch compared with thin strings.<span />
