What is the difference between synoptic and prognostic charts? 2. How are prognostic charts different from synoptic weather maps? Prognostic charts are computer generated forecast showing the expected pressure pattern at a specific future time. Synoptic weather maps describe the state of the atmosphere over a large area at a given moment. What is good […]

How many pounds of nitrogen per acre are needed for corn? 250 pounds How much nitrogen do you put in a hay field? “Apply 50 to 60 pounds per acre of nitrogen on your best grass stands and 30 to 40 pounds per acre on the rest,” he recommends. Thomas suggests a similar amount of […]

What are two examples of colloids? Examples of colloid are mayonnaise, milk, butter, gelatin, jelly, muddy water. What are the 4 types of colloids? The types of colloids includes sol, emulsion, foam, and aerosol. Sol is a colloidal suspension with solid particles in a liquid. Emulsion is between two liquids. Foam is formed when many […]

How do I combine two plots in R? Combining Plots R makes it easy to combine multiple plots into one overall graph, using either the. With the par( ) function, you can include the option mfrow=c(nrows, ncols) to create a matrix of nrows x ncols plots that are filled in by row. The layout( ) […]

Is hail a solid or liquid? Hail actually falls as a solid. Hailstones are formed by layers of water attaching and freezing in a large cloud. A frozen droplet begins to fall from a cloud during a storm, but is pushed back up into the cloud by a strong updraft of wind. When the hailstone […]

How do electrolytic cells work? An electrolytic cell converts electrical energy into chemical energy. Here, the redox reaction is spontaneous and is responsible for the production of electrical energy. The reaction at the anode is oxidation and that at the cathode is reduction. Here, the anode is positive and cathode is the negative electrode. What […]

What state is Tornado Alley 2020? Although the official boundaries of Tornado Alley are not clearly defined, the main alley extends from northern Texas, through Oklahoma, Kansas, Nebraska, Iowa, and South Dakota. States such as Minnesota, Wisconsin, Illinois, Indiana, Missouri, North Dakota and Ohio are sometimes included in Tornado Alley. What is the farthest a […]

What is the relationship between volume and pressure for a gas? It is summarized in the statement now known as Boyle’s law: The volume of a given amount of gas held at constant temperature is inversely proportional to the pressure under which it is measured. Are volume and temperature directly proportional? The volume of a […]

Which element stops fusion in a high mass star? iron What stars High Mass? High mass stars (stars with masses greater than three times the mass of the Sun) are the largest, hottest and brightest Main Sequence stars and blue, blue-white or white in colour. Supernovae release these elements into space making them available to […]

Will a capacitor save my battery? A stiffening capacitor will maintain voltage supplied to your amplifier. A car audio capacitor will help limit your headlight dimming because the amp is absorbing the voltage through the capacitor rather than your main battery, but it will not completely cure the problem. Is capacitor like a battery? A […]
