Instead, think of Jane Technologies as the Shopify of weed, and it’s an important distinction. While other startups attempt to build a destination marketplace like Amazon, Jane Technologies i...A hydrated ion is one kind of a complex ion (or, simply, complex), a species formed between a central metal ion and one or more surrounding ligands, molecules or ions that contain at least one lone pair of electrons, such as the [Al (H 2 O) 6] 3+ ion. A complex ion forms from a metal ion and a ligand because of a Lewis acid–base interaction.

Jan 30, 2023 · Which best describes stellar equilibrium? heart. 21. verified. Verified answer. Jonathan and his sister Jennifer have a combined age of 48. If Jonathan is twice as ... This is because solids have a fixed volume, and density is defined as mass per unit volume. Since neither mass nor volume change with temperature for solids, the density remains constant. Therefore, the density of lead at 90°C remains as 11.3 x 10³ kg/m³, the same as at 0°C. The concept that a solid's density doesn't change with temperature ...

Chapter 14 Astronomy. Hydrostatic Equilibrium. Click the card to flip 👆. The structure of the Sun is a matter of balance between the pressure outward and the force of gravity inward: this balance is known as hydrostatic equilibrium. The pressure results from energy finding its way to the surface of the Sun from deep in its interior.Assume that the star is in thermal equilibrium - i.e. at each radius the gas is neither heating up nor cooling down with time. Let the rate of energy generation per unit mass be q (with units erg s-1 g-1). Then: r Shell, mass dm = 4pr2rdr Luminosity at r: L(r) Luminosity at r+dr: L(r)+dL † dL=4pr2rdr¥q dL dr =4pr2rq 4th stellar structure ...

In a fusion reaction, the outward pressure of the hydrogen gas keeps the star in equilibrium. A collapse of the star would be unavoidable if the pressure became too great. short textured haircut womens Best Answer. Copy. In a full moon, the Moon is on the other side of Earth from the Sun.

The dynamic equilibrium, on the other hand, is the point at which products are being generated as fast as they are falling apart. This may not be the same as the chemical equilibrium, as enzymes force many reactions far past ... rafael quintanawhere did austin reaves go to schoolstate men's basketball Short-run equilibrium. An economy is in short-run equilibrium when the aggregate amount of output demanded is equal to the aggregate amount of output supplied. In the AD-AS model, you can find the short-run equilibrium by finding the point where AD intersects SRAS. The equilibrium consists of the equilibrium price level and the equilibrium output.
