What is shear strain equal to? Shear strain is defined by the ratio of the largest displacement Δx to the transverse distance L0. shear strain=ΔxL0. shear strain = Δ x L 0 . Shear strain is caused by shear stress. Shear stress is due to forces that act parallel to the surface. What is shear […]

How do I calculate change in velocity?
How do I calculate change in velocity? Multiply the acceleration by time to obtain the velocity change: velocity change = 6.95 * 4 = 27.8 m/s . Since the initial velocity was zero, the final velocity is equal to the change of speed. You can convert units to km/h by multiplying the result by 3.6: […]
Why do stars move when I stare at them?
Why do stars move when I stare at them? You’re absolutely right that stars twinkle — and sometimes appear to move around — due to our atmosphere “scrambling” their light as it travels from the top of Earth’s atmosphere to the ground. First, stars close to the horizon twinkle more because their light must travel […]
What are the characteristics of a groundwater?
What are the characteristics of a groundwater? Some of the most typical characteristics of groundwater are weak turbidity, a constant temperature and chemical composition and almost overall absence of oxygen. Circulating groundwater can have extreme variation in the composition with the appearance of pollutants and various contaminants. What is groundwater hydrology? Hydrogeology is the study […]

Why is hole mobility less?
Why is hole mobility less? Conduction electrons (free-electrons) travel in the conduction band and valence electrons (holes) travel in the valence band. Since holes are subjected to the stronger atomic force pulled by the nucleus than the electrons residing in the higher shells or farther shells, holes have a lower mobility. How is carrier mobility […]
Why does current change from positive to negative?
Why does current change from positive to negative? The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires […]
