What is the force of gravity in Newtons? G represents the gravitational constant, which has a value of 6.674⋅10−11N(m/kg)2 6.674 ⋅ 10 − 11 N (m/kg) 2 . Because of the magnitude of G , gravitational force is very small unless large masses are involved. Is gravity a pushing force? In general relativity, gravity neither […]

Why do water bottles have an air hole?
Is viscosity dependent on temperature?
Is viscosity dependent on temperature? According to the kinetic theory of gases, viscosity should be proportional to the square root of the absolute temperature, in practice, it increases more rapidly. With high temperatures, viscosity increases in gases and decreases in liquids, the drag force will do the same. Does salt increase surface tension? Yes, adding […]

Is the image real or virtual erect or inverted?
Is the image real or virtual erect or inverted? Real images (images on the same side of the object) are always inverted. Virtual images (images on opposite side of an object) are always erect/ upright. How do you tell if an image is real or virtual? (You will have no trouble remembering this if you […]
What are the types of vesicular transport?
What are the types of vesicular transport? Vesicles or other bodies in the cytoplasm move macromolecules or large particles across the plasma membrane. There are two types of vesicle transport, endocytosis and exocytosis (illustrated in Figure below). How can you prevent endocytosis? To avoid the problem of non-specific effects of chemical inhibitors, genetic approaches have […]
