What is the formula for impulse? An impulse is equal to the net force on the object times the time period over which this force is applied. Below, we derive impulse from the equation F = ma, which comes from Newton’s second law of motion. What type of word is impulse? noun. an impelling force […]

When can I come or when I can come? But if it’s a question: What time should I be there? Which one is correct “when should I come” or “when will I come”? Both sentences are grammatically correct. “When will I come?” expresses volition (i.e., willingness, determination or promise). How honest should you be in […]

Do the toilets in Australia flush backwards? Australian Toilets Don’t Flush Backwards Because of the Coriolis Effect. The real cause of “backwards”-flushing toilets is just that the water jets point in the opposite direction. Which way does the toilet flush in Australia? Water rotating clockwise in Australia and counterclockwise in the States? It’s a myth. […]

What is the word equation for sodium hydroxide and hydrochloric acid? Let’s see how a neutralization reaction produces both water and a salt, using as an example the reaction between solutions of hydrochloric acid and sodium hydroxide. The overall equation for this reaction is: NaOH + HCl → H2O and NaCl. What happens when sodium […]

What causes rightward shift in supply curve? Price of the product: When there is an increase in the price of the product and if it is more than the marginal cost of production, it enables the firm to earn excess profit by selling at a higher price. So, there is an increase in the supply […]

What would be a good warm up for golfing? Warming up properly before you stretch or swing a club is pretty easy. You can do something as simple as making a few slow-motion golf swings, taking a brisk walk, or doing a few squats and lunges — anything that gets your heart rate up and […]

How does temperature affect viscosity of magma? MAGMA VISCOSITY, TEMPERATURE, AND GAS CONTENT. The effect of temperature on viscosity is intuitive. Like most liquids, the higher the temperature, the more fluid a substance becomes, thus lowering its viscosity. Composition plays an even greater role in determining a magma’s viscosity. What are the factors that affects […]

What is the nuclear charge of an atom with a mass of 23 and an atomic number of 11? What is the nuclear charge of an atom with a mass of 23 and an atomic number of 11? How do you figure this out? Would the answer be (1) 11+ since the atomic number is […]

What does it mean if an element has 8 valence electrons? The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds. How many valence electrons does s 32 have? 6 […]

What are separation techniques? Such separation techniques include filtration or evaporation. Separation process, or a separation method, or simply a separation, is a methodology to attain any mass transfer phenomenon that converts a mixture of substances into two or more distinct product mixtures. What are the steps for crystallization? There are five major steps in […]
