When a capillary tube is dipped in water vertically? The capillary tube is dipped in water vertically it is sufficiently long so that water rises to maximum height h in the tube te length of the portion immersed in water is `lgth`. The lower end of the tube is closed the tube is taken out […]
Is a space lift possible?
Is a space lift possible? A space elevator is possible with today’s technology, researchers say (we just need to dangle it off the moon) Space elevators would dramatically reduce the cost of reaching space but have never been technologically feasible. Is a space antenna possible? Ad Astra’s massive space antenna isn’t real, but scientists do […]
Is the ratio of absolute viscosity to mass density?
Is the ratio of absolute viscosity to mass density? The ratio of absolute viscosity to mass density is known as. viscosity index. What is the relation between dynamic viscosity and kinematic viscosity? One way is to measure a fluid’s resistance to flow when an external force is applied. This is dynamic viscosity. The other way […]
How are thermodynamic properties classified?
How are thermodynamic properties classified? Properties are classified as either intensive or extensive. Properties are intensive if independent of the amount of mass present and extensive if a function of the amount of mass present. Properties such as pressure, temperature, and density are intensive, whereas volume and mass are extensive. What are the thermodynamic properties? […]
What kind of bonding is there in semiconductors?
What kind of bonding is there in semiconductors? covalent bonds What is the difference between a conductor and a semiconductor? Difference between Semiconductors and Conductors The conductor has a large number of electrons for transmission, whereas semiconductor has a very little number of electrons for transmission. The flow of current in a conductor is due […]
What are the two main categories of machine movement?
What are the two main categories of machine movement? Motions. Power. Type. What are the different types of guards? There are four general types of guards: Fixed. Interlocked. Adjustable. Self-adjusting. What are the three main areas of a machine? Machine Guarding eTool | Introduction. All machines consist of three fundamental areas: the point of operation, […]
What type of reaction is melting?
What type of reaction is melting? Melting, or fusion, is a physical process that results in the phase transition of a substance from a solid to a liquid. This occurs when the internal energy of the solid increases, typically by the application of heat or pressure, which increases the substance’s temperature to the melting point. […]
Which of the following is an example of irreversible process?
Which of the following is an example of irreversible process? Irreversible processes are characterized by the flow of fluids with friction, and sliding friction between any two matters. An example of an irreversible process is electric current flow through a conductor with a resistance. An example of an irreversible process is magnetization or polarization with […]
What is the process of fluid distribution throughout the body?
What is the process of fluid distribution throughout the body? Water passes from the intestinal lumen into plasma mainly by passive transport, regulated by osmotic gradients. Water molecules are then transported via blood circulation to be distributed all over the body, to the interstitial fluids and to cells. How does fluid move between ECF and […]
Why does drag force increase with speed?
Why does drag force increase with speed? Terminal Velocity The downward force of gravity remains constant regardless of the velocity at which the person is moving. However, as the person’s velocity increases, the magnitude of the drag force increases until the magnitude of the drag force is equal to the gravitational force, thus producing a […]
