What does it mean when a nucleus is stable? Definition. Nuclear stability means that the nucleus of an element is stable and thus it does not decay spontaneously emitting any kind of radioactivity. Those nuclei with the highest binding energy per nucleon are the most stable with respect to destructive nuclear reactions. What is the […]
Does all the ice melt calorimetry?
Does all the ice melt calorimetry? Once all the ice has melted, the temperature of the liquid water rises, absorbing heat at a new constant rate. At 100oC the water begins to boil….Heat and Change in Physical State. Substance Mercury Melting Point (oC) –38.9 ΔHfus, (J/g) 11.8 Boiling Point (oC) 357 ΔHvap (J/g) 272 When […]
Why is Nhst bad?
Why is Nhst bad? NHST is unsuitable for large datasets Most NHST studies rely on nil null hypothesis testing (Nickerson, 2000) which means that H0 expects a true mean difference of exactly zero between conditions with some variation around this true zero mean. The p-value is smaller if the test statistic is larger. Why is […]
When a slab of dielectric medium is placed between plates of a parallel plate capacitor which is connected with a battery then the charge on plates in comparison with earlier charge?
When a slab of dielectric medium is placed between plates of a parallel plate capacitor which is connected with a battery then the charge on plates in comparison with earlier charge? Two identical capacitors are connected as shown in the figure. A dielectric slab is introduced between the plates of one of the capacitors so […]
What are the benefits of subject design?
What are the benefits of subject design? The main advantage that the within subject design has over the between subject design is that it requires fewer participants, making the process much more streamlined and less resource heavy. For example, if you want to test four conditions, using four groups of 30 participants is unwieldy and […]
What are the methods of measuring resistance?
What are the methods of measuring resistance? Measurement of Medium Resistance (1Ω – 100kΩ) Ammeter-Voltmeter Method. Wheatstone Bridge Method. Substitution Method. Carey- Foster Bridge Method. Ohmmeter Method. Which method is used for high resistance? Two methods are used to measure high resistance, the constant voltage method and the constant current method. In the constant- voltage […]
Can an explosion trigger an earthquake?
Can an explosion trigger an earthquake? A nuclear explosion can cause an earthquake and even an aftershock sequence. However, earthquakes induced by explosions have been much smaller than the explosion, and the aftershock sequence produces fewer and smaller aftershocks than a similar size earthquake. Not all explosions have caused earthquakes. Can a nuke cause a […]
Is pcl5 an ionic compound?
Is pcl5 an ionic compound? Phosphorus pentachloride Is PCl5 both ionic and covalent? PCl5 is a covalent in gaseous and liquid states but ionic in solid state. Is MoCl6 ionic compound? The result is an electron-pair sharing bond which looks a lot like a covalent bond between Mo & Cl with one electron from Mo […]
How many natural realms are there what are they?
How many natural realms are there what are they? The Four Great Realms: The natural systems encountered in physical geography operate within the four great realms, or spheres, of the Earth. These are the atmosphere; the lithosphere, the hydrosphere, and the biosphere. What are the 3 realms of earth? 3 — EARTH SURFACE REALMS. We […]
