What is the difference between P waves and S waves in term of speed? Wave Speeds P waves travel faster than S waves, and are the first waves recorded by a seismograph in the event of a disturbance. P waves travel at speeds between 1 and 14 km per second, while S waves travel significantly […]
How is the movement of molecules measured?
How is the movement of molecules measured? Molecular motion is defined as the movement of constituent particles or molecules in a certain direction. The molecular motions are affected by heat and temperature. This is because the temperature is the measurement of the average kinetic energy of the molecules and represents the motion of molecules. How […]
What is the balanced equation for Fe H2SO4 FeSO4 H2?
Why is there no tide in the Caribbean?
Why is there no tide in the Caribbean? Most of the Caribbean islands are really islands out in the ocean with not so much topography to alter the way the tidal bulge is distributed. Channels between island will routinely see higher currents than surrounding areas because more water has to get between the islands to […]
Which is conservative force?
Which is conservative force? Conservative force, in physics, any force, such as the gravitational force between the Earth and another mass, whose work is determined only by the final displacement of the object acted upon. Stored energy, or potential energy, can be defined only for conservative forces. Are all conservative forces Central? In classical mechanics, […]
Why is propeller feathering necessary?
Why is propeller feathering necessary? On single-engined aircraft, whether a powered glider or turbine-powered aircraft, the effect is to increase the gliding distance. On a multi-engine aircraft, feathering the propeller on an inoperative engine reduces drag, and helps the aircraft maintain speed and altitude with the operative engines. What is full feathering propeller? A constant-speed […]
What is the mass of 1 cm3 of water?
Why is water an excellent solvent?
Why is water an excellent solvent? Water is capable of dissolving a variety of different substances, which is why it is such a good solvent. Water molecules have a polar arrangement of the oxygen and hydrogen atoms—one side (hydrogen) has a positive electrical charge and the other side (oxygen) had a negative charge. How do […]
What are the disadvantages of a pneumatic system?
What are the disadvantages of a pneumatic system? Loud, Leaks and Water Control and speed in pneumatic systems are more difficult because of the compressed air than compared with electrical or hydraulic systems. If for instance, a device requires a specific speed, you might have to add more equipment to the pneumatic system to make […]
What is the pressure 10m underwater?
What is the pressure 10m underwater? The pressure increases about one atmosphere for every 10 meters of water depth. At a depth of 5,000 meters the pressure will be approximately 500 atmospheres or 500 times greater than the pressure at sea level. Is 29 high barometric pressure? A barometer reading of 30 inches (Hg) is […]
