How do you find the hypothesis in a research study? The first few paragraphs of a journal article serve to introduce the topic, to provide the author’s hypothesis or thesis, and to indicate why the research was done. A thesis or hypothesis is not always clearly labled; you may need to read through the introductory […]
What is the type of mass of spread?
What is the type of mass of spread? e) Spreads: A spread is an extension of a cohesive soil or rock mass combined with a general subsidence of the fractured mass of cohesive material into softer underlying material. The rupture surface is not a surface of intense shear. Spreads may result from liquefaction or flow […]
What do polar solvents dissolve?
What do polar solvents dissolve? The rule of thumb is that “like dissolves like”. Polar/ionic solvents dissolve polar/ionic solutes and non-polar solvents dissolve non-polar solutes. For example, water is a polar solvent and it will dissolve salts and other polar molecules, but not non-polar molecules like oil. What are two factors that affect the solubility […]
What are the five imaginary lines?
What are the five imaginary lines? Top 20 imaginary lines on Earth Equator: This is the king of all imaginary lines. Prime Meridian: This line marks zero degrees longitude, and is actually quite arbitrary. Missouri Compromise Line: Tropic of Capricorn: 38th parallel north: Mason-Dixon Line: Washington meridian: 49th parallel north: What two imaginary lines go […]
Which of the following elements is the most reactive Cl Br or I?
Which of the following elements is the most reactive Cl Br or I? 1 Expert Answer Mike – I can tell you the order of reactivity for these specific nonmetals, I<Br<Cl, therefore, Cl is the most reactive nonmetal in this list. Is nitrogen gas heavier than oxygen? Oxygen is denser than both air and nitrogen, […]
What are two properties of oxygen?
What are two properties of oxygen? The Physical Properties of Oxygen are as follows: Color : Colorless. Phase : Gas. Odor : Oxygen is an odorless gas. Taste : A tasteless gas. Conductivity : A poor conductor of heat and electricity. Solubility : Slightly soluble in water, alcohol and some other common liquids. Density : […]
How is science used in basketball?
How is science used in basketball? Basketballs bounce because of the pressurized air inside of them, gravity and Newton’s Laws of Motion. When you dribble a basketball, your hand and gravity both push the ball towards the ground (Law #1). The energy in the compressed air is transferred back to the ball pushing it back […]
How are alkali metals extracted?
How are alkali metals extracted? Alkali metals are generally extracted by electrolysis of their ores. Only electrolytic method is suitable because of high reactive nature of alkali metals. Why do alkali metals have low density? Since alkali metals have a large atomic size and low atomic weight, they have low density. What are the properties […]

Why does a comb attract hair?
Why does a comb attract hair? The charge on the screen attracts dust. The molecules orientate their dipoles, the negative oxygen towards the comb; the positively charged hydrogens away from it. When you comb your hair with a nylon comb, both the comb and your hair become charged. The comb and your hair acquire opposite […]
