Is nuclear power eco friendly? Nuclear energy is considered by some as ecological energy in the sense that producing electricity with nuclear fission emits almost no CO2 or fine particles. On the contrary, coal or oil, and even gas, when put into combustion to produce electricity (or heat, or to power an engine), emit CO2 […]
What are the five characteristics of fungi?
What are the five characteristics of fungi? Characteristics of Fungi Fungi are eukaryotic organisms means they have true nucleus which are enclosed in membranes. They are non-vascular organisms. Fungi have cell walls (plants also have cell walls, but animals have no cell walls). There is no embryonic stage for fungi. They reproduce by means of […]
What is the relationship between temperature and height in the mesosphere?
What is the relationship between temperature and height in the mesosphere? The mesosphere is directly above the stratosphere and below the thermosphere. It extends from about 50 to 85 km (31 to 53 miles) above our planet. Temperature decreases with height throughout the mesosphere. The coldest temperatures in Earth’s atmosphere, about -90° C (-130° F), […]
Does ice melt at 2 degrees?
What is the value of the spring constant k?
How does the nucleus change in beta decay?
How does the nucleus change in beta decay? A beta results in a neutron emitting a high energy electron and becoming a positive proton. Beta decay changes the atomic number of the nucleus by increasing the number of protons, by decreasing the number of neutrons while leaving the atomic mass essentially the same. What does […]
Will and would uses?
Will and would uses? And English learners often get these two confused because they’re used in very similar situations. But they’re not the same. The main difference between will and would is that will is used for real possibilities while would is used for imagined situations in the future. Can Model sentences? She can drive […]
Is a higher moment of inertia better?
Is a higher moment of inertia better? Higher moments of inertia indicate that more force has to be applied in order to cause a rotation whereas lower moments of inertia means that only low forces are necessary. Masses that are further away form the axis of rotation have the greatest moment of inertia. What is […]
How do you find velocity before hitting the ground?
What is the evidence for Pangea?
What is the evidence for Pangea? Glacial deposits, specifically till, of the same age and structure are found on many separate continents that would have been together in the continent of Pangaea. Fossil evidence for Pangaea includes the presence of similar and identical species on continents that are now great distances apart. Why did people […]
