<span>Radiometric dating such as carbon 14, Uranium 238, 235, and 234, Thorium 232, Rubidium 87, and Potassium 40. This is not an exhaustive list. Each of these different isotopes have a different half life, so they can be used to measure different ages, from million to billions of years.</span>
A) In Canada there's more hardwood and thus it is more common in the forest product output.
b) The hardwood is predominantly on the north. Hardwood trees are the trees that usually prefer colder climates and since there's not much landmass on the south half on the Earth closer to the pole, they are mostly on the north.
c) Softwood: Pine, Cedar, Cypress . Hardwood: Oak, Birch, Poplar.
If an object that is put in a fluid weighs more than the weight of the fluid it displaces, it will sink. Buoyancy is then, directly related to the weight, or density, of the fluid. A more dense, or heavier fluid will then have the ability to “float” heavier objects. true floating object must be wholly above the surface of the liquid. all objects that float must contain some trapped air and that is the only reason why they float. the amount of liquid on which the object floats matters somehow, i.e. an object will float higher in a larger volume or deeper liquid. The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in. If the density of an object in the fluid is greater than the density of the fluid, the object will sink. If the density is less than that of the fluid, the object will float upward due to the buoyancy from the fluid. Buoyant force is the product of displaced volume times density of the fluid times the acceleration due gravity. Hence increasing the density of fluid will increase the buoyant force.
