Answer:
c). Very little plastic and elastic deformation
Explanation:
Brittle failure is a sudden, very rapid crack where there is no sign of any plastic deformation or ductility. The failure is not stable unlike ductile failure and the the crack propagates very fast without any further increase of any stress. In brittle failure there is very little plastic deformation and low energy is absorbed before fracture takes place.
Thus, very little plastic and elastic deformation takes place in brittle failure.
The answer is prototype, or the first choice. hope this helps (:
Answer:
Option C
In the membrane that covers axons
Explanation:
Voltage-regulated channels allow for selective passage of different beneficial ions such as potassium and are found on the surface of a wide variety of cells such as nerve, muscle, and secretory cells. They mainly regulate cell membrane excitability, repetitive low frequency firing in some neurons, and recover the nerve fiber membrane.
Answer:
3150 L/min
Explanation:
The volume of the room is the product of the height of the room and its area. It is given as:
Volume (V) = height (h) × Area (A)
V = h × A
Height = 2.7 m, Area = 200 m². Hence:
V = h × A = 2.7 × 200 = 540 m³
The flow capacity (
) is given by
ACH = air changes per hour = 0.35
But 1 m³ = 1000 L, 1 hr = 60 min
