How do you dissolve soda ash? The soda ash dissolves very easily and the half-full jug is easier to shake than a full one….To mix a gallon of soda ash solution: Pour 1/2 cup soda ash powder into the jug. Fill the jug halfway with very warm water. Shake the jug to dissolve the soda […]
Why do we need a resistor connected to the base of the transistor?
Which crystalline structure is a common structure of metals?
Which crystalline structure is a common structure of metals? Most metals and alloys crystallize in one of three very common structures: body-centered cubic (bcc), hexagonal close packed (hcp), or cubic close packed (ccp, also called face centered cubic, fcc). What are the three most common metal crystal structures? Common Crystal Structures Three crystal structures favored […]
Which is an example of damage caused by straight line winds FEMA?
Which is an example of damage caused by straight line winds FEMA? DOWN-BURSTS ARE ONE EXAMPLE OF DAMAGING STRAIGHT LINE WINDS. A DOWN-BURST IS A SMALL AREA OF RAPIDLY DESCENDING RAIN AND RAIN-COOLED AIR BENEATH A THUNDERSTORM. WIND SPEEDS IN SOME OF THE STRONGER DOWN-BURSTS CAN REACH 100 TO 150 MILES PER HOUR WHICH IS […]
What do the particles of air inside the balloon do when the air around it is removed?
What do the particles of air inside the balloon do when the air around it is removed? When air is removed from the vacuum chamber, the gases in the balloon will expand to fill the container. Liquid nitrogen is cold enough to convert carbon dioxide gas particles to a solid. As the particles of carbon […]
What does a higher factor of safety mean?
What does a higher factor of safety mean? Factor of safety (FoS) is ability of a system’s structural capacity to be viable beyond its expected or actual loads. If the consequences of failure are significant, such as loss of life, personal harm or property loss, a higher FoS is likely to be required by design […]
What are the parts of a roller coaster?
What are the parts of a roller coaster? Common elements Banked turn. Brake run. Buzz bars. Drive tire. Headchopper. Helix. Launch track. Lift hill. What holds up a roller coaster? The track and lift chain on both wooden and steel coasters are made of steel, and the cars usually have steel axles and substructures. The […]
How hot do hot water pipes get?
How hot do hot water pipes get? 140 degrees Fahrenheit Will turning up water heater make hot water last longer? Turning up the heat at the water heater causes hotter water to go to the hot tap. This makes the perceived hot water in your tank last longer. However, turning up the temperature will cost […]
What wage will the Monopsonistic employer pay its workers?
What wage will the Monopsonistic employer pay its workers? A monopsony employer faces a supply curve S, a marginal factor cost curve MFC, and a marginal revenue product curve MRP. It maximizes profit by employing Lm units of labor and paying a wage of $4 per hour. The imposition of a minimum wage of $5 […]
How is the failure of ductile and brittle materials under bending load?
How is the failure of ductile and brittle materials under bending load? Brittle materials do not undergo significant plastic deformation. They thus fail by breaking of the bonds between atoms, which usually requires a tensile stress along the bond. Micromechanically, the breaking of the bonds is aided by presence of cracks which cause stress concentration. […]
