How does a commercial refrigeration system work? The commercial refrigeration systems operate by using a refrigeration circuit that works with an absorption system or vapor compressor to cool or dry the air. The general principle of refrigeration expands the liquid into a gas and eliminates heat from the local area. What are the different types […]

What are the properties of stiffness matrix?
What are the properties of stiffness matrix? Properties of stiffness matrix Order of stiffness matrix corresponds to total dofs. Singular stiffness matrix means structure is unconstrained and rigid body motion. Each column of stiffness matrix is an equilibrium set of nodal force required to produce unit respective dof. Does stiffness matrix have to be symmetric? […]
How many chromosomes does an egg or a sperm have?
How many chromosomes does an egg or a sperm have? Diploid is a cell or organism that has paired chromosomes, one from each parent. In humans, cells other than human sex cells, are diploid and have 23 pairs of chromosomes. Human sex cells (egg and sperm cells) contain a single set of chromosomes and are […]
Where does salt go when it dissolves in water?
Where does salt go when it dissolves in water? Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows. Once this happens, the salt is dissolved, resulting […]
What happens when a hydrogen atom changes from the excited state to the ground state?
What do u mean by relative velocity?
What is not considered to be a standard in measurement?
What is not considered to be a standard in measurement? Most measuring tools and instruments, such as a ruler or a scale, use standard units of measurement. Nonstandard units of measurement are units of measurement that aren’t typically used, such as a pencil, an arm, a toothpick, or a shoe. What is a measurement standard […]
When NaCl is dissolved in water what ions are formed?
When NaCl is dissolved in water what ions are formed? When sodium chloride is dissolved in water, the polar water molecules are able to work their way in between the individual ions in the lattice. The water molecules surround the negative chloride ions and positive sodium ions and pull them away into the solution. This […]
What are 4 things that happen during telophase?
What are 4 things that happen during telophase? Telophase. During telophase (Figure below), the chromosomes begin to uncoil and form chromatin. This prepares the genetic material for directing the metabolic activities of the new cells. The spindle also breaks down, and new nuclear membranes (nuclear envelope) form. How do you detect telophase? When you look […]
