What is the unit of uniformly distributed load? Uniformly distributed load The load may be represented as rate per lineal metre (kN/m) for beams, or as a rate per square metre (kN/m2) for slabs. A diagram shows a beam with the load distributed all along its length. The load is labelled UDL with units shown […]
What is egg drop project?
What is egg drop project? The Classic “Egg-Drop” experiment has been a standard in science instruction for many years. Essentially, students are asked to construct some type of container that will keep a raw egg from cracking when dropped from ever-increasing elevations. What does the egg drop experiment prove? Egg drop projects help students explore […]
What would happen if you stroke an iron nail with a magnet?
What would happen if you stroke an iron nail with a magnet? If you stroke an iron nail with a bar magnet, the nail will become a permanent (or at least long-lasting) magnet. Its magnetic domains will remain aligned even after you remove it from the magnetic field of the bar magnet. What does the […]
What is the biosphere made of?
What is the biosphere made of? The biosphere is made up of the parts of Earth where life exists—all ecosystems. The biosphere extends from the deepest root systems of trees, to the dark environments of ocean trenches, to lush rain forests, high mountaintops, and transition zones like this one, where ocean and terrestrial ecosystems meet. […]
Can enzymes work backwards?
Can enzymes work backwards? Enzymes catalyze biochemical reactions. Enzymes and chemical catalysts increase the rate of a chemical reaction in both directions, forward and reverse. This principle of catalysis follows from the fact that catalysts can’t change the equilibrium of a reaction. Do enzymes affect free energy? Enzymes do not affect the Gibbs free energy […]
What do solubility tests indicate?
What do solubility tests indicate? Solubility tests can suggest the size and polarity of an unknown compound and the presence of basic or acidic functional groups. A compound’s solubility in aqueous acid or base involves ionization of the compound and, therefore, a chemical reaction. The salts produced are water-soluble. What factors affect solubility? Solubility is […]

What are three main factors that influence soil color?
What are three main factors that influence soil color? What determines soil colour? Mineral matter derived from the constituents of the parent material. Organic matter. The nature and abundance of iron. Moisture content. What are the five color classes for surface soils? Soil color can be grouped into four broad classes: 1) dark brown, very […]
What is the formula of critical temperature?
Is Madame Curie still radioactive?
Is Madame Curie still radioactive? Marie Curie died on July 4, 1934, at the age of sixty six. Now, more than 80 years since her death, the body of Marie Curie is still radioactive. The Panthéon took precautions when interring the woman who coined radioactivity, discovered two radioactive elements, and brought X-rays to the frontlines […]
