How do you calculate backfill on a retaining wall? Multiply the length of the wall by the desired height, then divide this number by 81 to determine the amount of backfill gravel needed. Add the backfill amount to the base amount to determine the total cubic yards of gravel necessary for completing the wall. How […]
What is the relationship between mass and inertia quizlet?
What is the relationship between mass and inertia quizlet? Terms in this set (4) The greater the mass, the greater the inertia, and vice versa. Remark: This means that a more massive object has a greater tendency to resist a change in its state of rest or motion. What is the relationship between weight and […]

What two things started Earth?
What two things started Earth? When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle and a solid crust. Why […]
Is the Carnot cycle 100% efficient?
Is the Carnot cycle 100% efficient? No,, never . It can be 100℅ only if the sink temperature is zero or the source temperature is infinite (very large value). Carnot is an ideal cycle is provides benchmark to compare efficiency of other cycles. Carnot efficiency is the maximum efficiency that can be achieved in a […]
Why is a car crash inelastic?
Why is a car crash inelastic? Collisions are considered inelastic when kinetic energy is not conserved, but this could be from either a loss or gain or kinetic energy. For example, in an explosion-type collision, the kinetic energy increases. It is common for people to try to conserve energy in a collision. What happens in […]
Why do waves not transfer matter?
Why do waves not transfer matter? A wave transports its energy without transporting matter. Waves are seen to move through an ocean or lake; yet the water always returns to its rest position. Energy is transported through the medium, yet the water molecules are not transported. Do waves transfer mass? Waves transfer energy but not […]
What does it mean when a nucleus is stable?
What does it mean when a nucleus is stable? Definition. Nuclear stability means that the nucleus of an element is stable and thus it does not decay spontaneously emitting any kind of radioactivity. Those nuclei with the highest binding energy per nucleon are the most stable with respect to destructive nuclear reactions. What is the […]
What are the benefits of subject design?
What are the benefits of subject design? The main advantage that the within subject design has over the between subject design is that it requires fewer participants, making the process much more streamlined and less resource heavy. For example, if you want to test four conditions, using four groups of 30 participants is unwieldy and […]
What happens to pressure if volume decreases in gas?
What happens to pressure if volume decreases in gas? Explanation: Gas particles exert pressure by colliding with the walls of their container. If you reduce the volume, you are effectively increasing the density of the particles and they will collide with the walls more frequently, leading to an increase in pressure. Why does the volume […]
