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 are the significant figure rules? To determine the number of significant figures in a number use the following 3 rules: Non-zero digits are always significant. Any zeros between two significant digits are significant. A final zero or trailing zeros in the decimal portion ONLY are significant. Which value from his calculation most strongly affects […]

What is lateral and longitudinal acceleration? The longitudinal acceleration is in g force again similar to the lateral load transfer. The g force value is “Ax”. If you have acceleration in meters per second squared then the below equation can be used to convert it into units of g. If the longitudinal acceleration is due […]

How can I check my PC power supply? To see which apps have used the most battery power on your PC, head to Settings > System > Battery. How do I check my power supply voltage? Switch your multimeter to the range that is appropriate for reading the voltage from your power supply. If your […]

What is the formula of isosceles? Area of an Isosceles Triangle Formulas Known Parameters of Given Isosceles Triangle Formula to Calculate Area (in square units) Base and Height A = ½ × b × h All three sides A = ½[√(a2 − b2 ⁄4) × b] Length of 2 sides and an angle between them […]

What bacteria are found in soil? There are three types of soil bacteria that fix nitrogen without a plant host and live freely in the soil and these include Azotobacter, Azospirillum and Clostridium. Figure 2: Nitrogen fixing Rhizobium bacteria form nodules on a soybean root. Where do soil organisms live? Soil organisms are concentrated: Around […]

What are the example of periodic? The definition of periodic is something that is recurring at regular intervals, or happens from time to time. An example of periodic is a person’s birthday happening once each year. An example of periodic is a person going to their favorite restaurant every once in awhile. What do you […]

What is the advantage of a distance-time graph? (i) It tells us about the position of the body at any instance of time. (ii) From the graph, we can see the distance covered by the body during a particular interval of time. (iii) It also gives us information about the velocity of the body at […]

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 are the conditions to form ionic bond Class 11? One of the atoms must be a metal and the other must be a non-metal. The metal atom should have very low ionization energy so that it can lose electrons easily to form cations (positively charged ions) i.e. metal atoms must be highly electropositive. What […]
