e) Use the law of acceleration and find the value of the acceleration of the body that falls freely.

Solutions

Expert Solution

The force acting on any object of mass m on the surface of the planet is its weight which is ma where a is the acceleration of the object.

The force of gravitation acting between the object of mass m and the planet is   where G is the universal gravitational constant, M is the mass of the planet and R is the radius of the planet.

When the object is freely falling, the weight of the object is balanced by the gravitational force between the object and the planet.

is the acceleration of the body that falls freely which only depends on the mass and radius of the planet and is independent of the mass m of falling object. .

Using beers law find the amount of pigment isolated in grams for beta carotene. The e is 139500m^-1*cm^-1 and mw is 536.88 g/mol and the final weight is 3.08ml. The chlorophyll a has an e of 32580 and mw of 893.48g/mol and final volume is 3.22 ml. The wavelength of beta carotene was found to be .544 at 450 nanometers and the chlorophyll a was .280 at 660nm not sure if this information is needed.

(a) A fundamental law of motion states that the acceleration of an object is directly proportional to the resultant force exerted on the object and inversely proportional to its mass. If the proportionality constant is defined to have no dimensions, determine the dimensions of force. (Use the following as necessary: M, L, and T.) (b) The newton is the SI unit of force. According to the results for (a), how can you express a force having units of newtons using...
