At what height the acceleration due to gravity will be reduced to 36% of its value? We can write the relation between actual acceleration due to gravity and the apparent acceleration due to gravity. Hence, the height above the surface of the earth where the acceleration due to gravity is reduced by 36% of its […]

Why is the crater important? The Planetary Deep Past Impact craters allow scientists to study a planet’s geological history—even when the records are buried beneath the surface. Rocks ejected by impacts contain minerals that formed in the presence of liquid water; some craters also show signs of ancient lakes. What is the biggest crater on […]

How do you calculate a pulley system? To calculate the mechanical advantage of a pulley you simply have to count the number of rope sections that support whatever object you are lifting (not counting the rope that is attached to the effort). For example, in a one pulley system the MA is 1. In a […]

Is biome a ecosystem? A biome is a large region of the world that has similar plants, animals and other organisms that are adapted to the terrain and weather of that region. An ecosystem is the interaction of plants and animals with nonliving things and each other. Is ecosystem bigger than community? The population, which […]

What is meant by components of velocity? Determining the Components of a Velocity Vector The two parts of a vector are known as components and describe the influence of that vector in a single direction. If a projectile is launched at an angle to the horizontal, then the initial velocity of the projectile has both […]

How do the equations y MX and Y KX compare? We can compare y = kx to the slope-intercept form of a line, y = mx + b. We can see that y = kx is a linear equation with slope k and y-intercept 0. This tells us that the graph of a direct variation […]

Does virtual mean in person? The adjective virtual is used to describe something that exists in essence but not in actuality. You may have made a virtual friend on an online gaming site, but don’t expect that person to meet you for coffee. Does virtual mean live? Virtual Meetings = Unified Communication Unified communication, or […]

What is the rate of change on a graph? A rate of change relates a change in an output quantity to a change in an input quantity. The average rate of change is determined using only the beginning and ending data. See (Figure). Identifying points that mark the interval on a graph can be used […]

What type of epithelial tissue looks stratified but is not? Pseudostratified columnar epithelium is a type of epithelium that appears to be stratified but instead consists of a single layer of irregularly shaped and differently sized columnar cells. In pseudostratified epithelium, nuclei of neighboring cells appear at different levels rather than clustered in the basal […]

How wages are determined? Just as in any market, the price of labor, the wage rate, is determined by the intersection of supply and demand. When the supply of labor increases the equilibrium price falls, and when the demand for labor increases the equilibrium price rises. What are the factors affecting wages and salary? The […]
