Is black body always black? No radiation passes through it and none is reflected, yet in classical physics, it can theoretically radiate any possible wavelength of energy. Despite the name, black bodies are not actually black as they radiate energy as well. What is a black body Class 11? A black body is an idealization […]

Does increasing effect size increase power?
Does increasing effect size increase power? The statistical power of a significance test depends on: • The sample size (n): when n increases, the power increases; • The significance level (α): when α increases, the power increases; • The effect size (explained below): when the effect size increases, the power increases. Why does increasing the […]
Why was the plum pudding model wrong?
Why was the plum pudding model wrong? He argued that the plum pudding model was incorrect. The symmetrical distribution of charge would allow all the α particles to pass through with no deflection. Rutherford proposed that the atom is mostly empty space. The atom now consisted of a positive nucleus with negative electrons in circular […]
What is an igneous or sedimentary rock that has been changed by extreme pressure and heat quizlet?
What is an igneous or sedimentary rock that has been changed by extreme pressure and heat quizlet? Metamorphic rocks form when high temperature and pressure alter existing igneous and sedimentary rocks. Metamorphic rocks can also be formed from other metamorphic rocks. Rock changes in Metamorphic Rocks. Rock changes into metamorphic form when it experiences intense […]
When a cannonball is fired from a cannon?
When a cannonball is fired from a cannon? This is called the principle of conservation of momentum . Momentum is conserved in collisions and explosions . Conservation of momentum explains why a gun or cannon recoils backwards when it is fired. When a cannon is fired, the cannon ball gains forward momentum and the cannon […]
What is the charge of an electron?
What is the charge of an electron? Electrons. Electrons are found in the periphery of the atom and have a charge of -1. They are much smaller than protons; their mass is 11836 amu. Typically in modeling atoms, protons and neutrons are regarded as stationary, while electrons move about in the space outside the nucleus […]
