What is a net of a rectangular prism? The net of a solid figure is formed when a solid figure is unfolded along its edges and its faces are laid out in a pattern in two dimensions. Nets of rectangular prisms are made up of rectangles and squares. What is the difference between a cube […]

What is the unique features of water transport? The three main characteristics of water transport are that it is slow, that it can carry large loads, and that it is relatively cheap. Modern ships can carry huge loads of cargo without using very much fuel per unit of cargo. This makes this type of transport […]

Does frequency change power? Frequency of the system will vary as load and generation change. Increasing the mechanical input power to a synchronous generator will not greatly affect the system frequency but will produce more electric power from that unit. Can I use a 60 Hz device in a 50 Hz power frequency? Electrical machines […]

Did I gain weight or am I just bloated? One easy way to tell the difference between bloat and belly fat is to note belly fat does not cause your stomach to expand wildly throughout the course of a day; bloat does. One other way to tell the difference between bloat and belly fat is […]

What happens when a diver gets the bends? Decompression sickness: Often called “the bends,” decompression sickness happens when a scuba diver ascends too quickly. Divers breathe compressed air that contains nitrogen. At higher pressure under water, the nitrogen gas goes into the body’s tissues. Will the bends go away on its own? In some cases, […]

What is real and apparent Expansivity? The real (or absolute) expansivity of a liquid is the fraction of its volume by which it expands per kelvin rise in temperature. The apparent expansivity of a liquid is the fraction of its volume by which the liquid appears to expand per kelvin rise in temperature when heated […]

Does saltwater freeze? Ocean water freezes just like freshwater, but at lower temperatures. Fresh water freezes at 32 degrees Fahrenheit but seawater freezes at about 28.4 degrees Fahrenheit , because of the salt in it. When seawater freezes, however, the ice contains very little salt because only the water part freezes. Why do oceans not […]

What is order triage? Order triage. Refers to classifying orders according to preestablished guidelines so that a company can prioritize how orders should be filled. Pick-to-light technology. In which orders to be picked are identified by lights placed on shelves or racks. Which forecasting technique tends to be appropriate when there is little or no […]

What happens if a torn ACL is not repaired? If nothing is done, the ACL injury may turn into chronic ACL deficiency. Your knee may become more and more unstable and may give out more often. The abnormal sliding within the knee also can hurt cartilage. It can trap and damage the menisci in the […]

How do you know if a reaction is endothermic or exothermic? An exothermic process releases heat, causing the temperature of the immediate surroundings to rise. An endothermic process absorbs heat and cools the surroundings.” Is Melting Chocolate endothermic? endothermic – An endothermic reaction occurs when the elements are absorbing the heat allowing the solution to […]
