What should I learn to draw first? The first thing that most drawing tutorials teach you to draw is shapes, starting with a sphere. After all, any object that you see around you can be constructed by using one, or a combination of, three different shapes: A circle – a sphere is a circle in […]

What are the 5 examples of transitions? 10 Types of Transitions Addition. “Also, I have to stop at the store on the way home.” Comparison. “In the same way, the author foreshadows a conflict between two minor characters.” Concession. “Granted, you did not ask ahead of time.” Contrast. “At the same time, what she said […]

What is the negative connection in a battery called? Energy cannot be created or destroyed, but it can be saved in various forms. One way to store it is in the form of chemical energy in a battery. When connected in a circuit, a battery can produce electricity. A battery has two ends — a […]

What is Plasmolysis give an example? Some real-life examples of Plasmolysis are: Shrinkage of vegetables in hypertonic conditions. Blood cell shrinks when they are placed in the hypertonic conditions. During extreme coastal flooding, ocean water deposits salt onto land. Spraying of weedicides kills weeds in lawns, orchards and agricultural fields. Does Cytolysis occur in animal […]

What was the shortest month ever? February Why is it called February? February is named after an ancient Roman festival of purification called Februa. The Roman calendar originally began in March, and the months of January and February were added later, after a calendar reform. Copper-alloy figure of Mars, the Roman god of war. When […]

How many impact tests are there? There are basically two types of impact tests: pendulum and drop weight. Izod, Charpy, and tensile impact are the most common of the pendulum type tests. What is the difference between Charpy impact test and Izod impact test? In the Charpy impact test, the sample lies flat on the […]

What is amplitude of signal? The amplitude of a variable is the measure of how far, and in what direction, that variable differs from zero. Thus, signal amplitudes can be either positive or negative. The time-domain sequences in Figure 1–3 presented the sample value amplitudes of three different waveforms. Is amplitude directly proportional to time? […]

Why is Lake effect snow so bad? The Physics of Lake-Effect Snow Cool air cannot hold as much moisture as warm air. If there is enough moisture, some of it condenses and falls as snow or rain. Is Lake effect snow dangerous? Lake Effect Snow Can Be Dangerous During the storm, more than five feet […]

How self-driving cars will impact society? The prospect of widespread use of driverless cars brings with it many benefits: fewer traffic accidents and the economic toll caused by property damage, injury or death that results. Energy costs will also be saved as these autonomous vehicles maximize driving efficiency and reduce traffic congestion. How much do […]

How quick can evolution happen? Across a broad range of species, the research found that for a major change to persist and for changes to accumulate, it took about one million years. How Fast Is human evolution? A study by anthropologists John Hawks, Henry Harpending, Gregory Cochran, and colleagues suggests that human evolution has sped […]
