Does a force meter measure weight? The weight of something (or someone) is the force caused by the pull of gravity on the mass of something (or someone). Weight is measured in Newtons (N) and is named after Sir Isaac Newton, who discovered gravity. A force meter (or Newton meter) is used to measure weight. […]
What temperature does it need to be to sunbathe?
What temperature does it need to be to sunbathe? 88° F: Perfect beach temperature. Hot enough that you have motivation to get in the water, not so hot that you bake too quickly. 90° F: Excellent sunbathing temperature. Is 25 degrees warm enough for the beach? Refreshing, but after a while it still feels too […]
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), […]
What is the value of the spring constant k?
Can mechanical waves be transmitted through empty space?
Can mechanical waves be transmitted through empty space? Mechanical waves require the particles of the medium to vibrate in order for energy to be transferred. Sound waves, as with all mechanical waves, CANNOT be transferred or transmitted through empty space (vacuum). What kind of waves travel more distance? The faster wave travels a greater distance […]
What powers does Congress not have?
What powers does Congress not have? Section 9. Powers Denied to Congress Clause 1. Importation of Slaves. In General. Clause 2. Habeas Corpus Suspension. Clause 3. Bills of Attainder and Ex Post Facto Laws. Clause 4. Taxes. Clause 5. Duties On Exports From States. Clause 6. Preference to Ports. Clause 7. Appropriations and Accounting of […]
What are the selection rules for vibrational transitions?
What are the selection rules for vibrational transitions? Thus, the selection rule for a harmonic oscillator transition is ∆v = ± 1. The physical meaning of the vibrational selection rule is this: The vibration must change the molecular dipole moment to have a non-zero (electric) transition dipole moment. Which transition between rotational energy levels is […]
Is nuclear power eco friendly?
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 […]
How do you find velocity before hitting the ground?
What is ab initio method in physics?
What is ab initio method in physics? In nuclear physics, ab initio methods seek to describe the atomic nucleus from the bottom up by solving the non-relativistic Schrödinger equation for all constituent nucleons and the forces between them. A significant challenge in the ab initio treatment stems from the complexities of the inter-nucleon interaction. What […]
