What are the limitations of investment casting? Disadvantages It can be difficult to cast objects requiring cores. This process is expensive, is usually limited to small casting, and presents some difficulties where cores are involved. Holes cannot be smaller than 1/16 in. Investment castings require longer production cycles compared to other casting processes. What is […]
What is the deepest part of the Challenger Deep?
What is the deepest part of the Challenger Deep? The Challenger Deep in the Mariana Trench is the deepest known point in Earth’s oceans. In 2010 the United States Center for Coastal & Ocean Mapping measured the depth of the Challenger Deep at 10,994 meters (36,070 feet) below sea level with an estimated vertical accuracy […]
How do centrifuges separate substances?
How do centrifuges separate substances? Centrifugation separates the components of heterogeneous mixtures. These include liquids in liquids, solids in liquids, and solids and liquids in gases. Centrifugation uses centrifugal force to move dense components to the outside of the container. This causes the solid to settle more rapidly and completely. What is centrifugation used to […]
What is a lever give two examples?
What is a lever give two examples? The class of lever depends on the location of the load, force, and fulcrum. Some examples of levers include more than one class, such as a nut cracker, a stapler, nail clippers, ice tongs and tweezers. Other levers, called single class levers include the claw end of a […]
Which waves move the fastest?
Which waves move the fastest? P waves travel fastest and are the first to arrive from the earthquake. In S or shear waves, rock oscillates perpendicular to the direction of wave propagation. In rock, S waves generally travel about 60% the speed of P waves, and the S wave always arrives after the P wave. […]
Is thermal energy removed or added in boiling?
Is thermal energy removed or added in boiling? particles, rise to the top of the liquid and escape from the container. In the graph above, notice the energy changes that occur as thermal energy is added. The kinetic energy of particles increases until the liquid reaches its boiling point. At the boiling point, the potential […]
Which bond is the strongest?
Which bond is the strongest? Covalent bond Are metallic bonds stronger than covalent? So, in metallic bond there is actually no overlapping between any two atoms. So , we can conclude that a covalent bond is more stronger than a metallic bond. Neither ionic nor covalent bond exist in metal -how could it can be […]
What are the two main studies of physical science?
What are the two main studies of physical science? In this lesson, we will discuss how physics and chemistry are considered to be the two main branches of physical science. We will also look at the overlap between physics and chemistry. What are the issues in science education? Some of the complex issues in the […]
