Will slinkies of different diameter use the same angle?
no because the diameter cam change but all the angles will stay the same.
How do you work this math problem a cylinder has the height of 10 meters and a diameter of 24 How much oil does it contain?
you multiply them the change it to liters
The changes that occur as the bronchial tree gets smaller are what?
Support structures change: irregular plates of cartilage replace the cartilage rings, and by the time the bronchioles are reached, the tube walls no longer contain supportive cartilage. Epithelium type changes: the mucosal epithelium things as it changes from pseudostratified columnar to columnar and then to cuboidal in the terminal bronchioles. Mucus-producing cells and cilia are sparse in the bronchioles. For this reason, most airborn debris found at or below the level of the bronchioles must be removed by macrophages in the alveoli. Amount of smooth muscle increases: the relative amount of smooth muscle in the tube walls increases as the passageways become smaller. A complete layer of circular smooth muscle in the bronchioles and the lack of supporting cartilage (which would hinder construction) allows the bronchioles to provide substantial resistance to air passage.
How do you change diameter to radius?
Divide the diameter by 2.
How do you change circumferance into diameter?
circumference/pi = diameter
How do you change a diameter to a radius?
The radius is half the diameter.
How would the circumference of a circle change if you doubled its diameter?
When you double the diameter, the circumference is also doubled.
How do you change daimeter to raduis?
Assuming that daimeter = diameter andraduis = radius, you simply divide diameter by 2.
How do you change a radius to a diameter?
Multiply the radius by 2.
Why artery called resistance vessels?
The contraction and relaxation of the smooth muscle in their walls can change their diameter, thus changing the level of pressure (large diameter yields low pressure and smaller diameter yields high pressure).
How does the circumference of a circle change if you double its diameter?
Since the equation for circumference is pi*d then if you double the diameter the circumference will be doubled.
How do you find out pi with the circumference and diameter?
pi is the circumference divided by the diameter. it is a set universal constant and will never change = 3.1415...
