What is the unit of de Broglie wavelength? nanometres What is de Broglie’s relationship? De Broglie proposed that as light exhibits both wave-like and particle-like properties, matter to exhibit wave-like and particle-like properties. On the basis of his observations, de Broglie derived a relationship between wavelength and momentum of matter. This relationship is known as […]

Is neutron degeneracy pressure bigger than electron degeneracy pressure? A white dwarf collapses into a neutron star when its mass overwhelms electron degeneracy pressure, and its mass gets compressed into neutrons. This would seem to imply that neutron degeneracy can support greater pressure than electron degeneracy. Why does a star explode after collapsing? The collapse […]

How long does it take to walk after spinal cord injury? How Long Does It Take to Walk After Spinal Cord Injury? Sometimes, the most physical recovery occurs within the first 6 months after spinal cord injury because the spinal cord experiences a heightened state of plasticity. Can you walk after a spinal injury? Depending […]

How far should I bike for a good workout? It’s more of a total-body workout than biking on the road, which is mostly a lower-body cardio workout. Plan to get on your bike and ride for 30-60 minutes, 3-5 days a week. Start every ride with a warm-up. Pedal at a slow, easy pace for […]

What is a technique? 1 : the manner in which technical details are treated (as by a writer) or basic physical movements are used (as by a dancer) also : ability to treat such details or use such movements good piano technique. 2a : a body of technical methods (as in a craft or in […]

What are the 3 characteristics of prokaryotic? The characteristics of prokaryotic cells are: Membrane bound cell organelles such as Mitochondria, Golgi apparatus, Chloroplasts are absent. A membrane bound well defined nucleus is absent. Genetic material is circular DNA and occurs naked in the cell cytoplasm. The cell size ranges from 0.1 to 5.0 micrometre in […]

What would happen if chemistry didnt exist? Without chemistry our lives would be dull, dark, boring, and short. Without chemistry people would die much younger from diseases such as bubonic plague, since we wouldn’t have antibiotics. We wouldn’t have vaccines, so people would still contract terrible illnesses such as smallpox and polio. Can humans survive […]

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 […]

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 […]
