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?
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? […]

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 […]
What bacteria are found in soil?
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.

How does the volume of air in a balloon affect the distance it travels?
Do both plants and animals have a chloroplasts?
Do both plants and animals have a chloroplasts? Both plant and animal cells are eukaryotic, so they contain membrane-bound organelles like the nucleus and mitochondria. For example, plant cells contain chloroplasts since they need to perform photosynthesis, but animal cells do not. What will happen if animal cells have chloroplast? A chloroplast dumped in to […]
When a current carrying conductor is kept in a magnetic field?
When a current carrying conductor is kept in a magnetic field? The force experienced by a current carrying conductor placed in a magnetic field is the maximum when the conductor is kept perpendicular to the direction of the magnetic field. Why does current carrying conductor kept in a magnetic field experience force? A current carrying […]
