When the mass moves away from he axis of the earth (or any spinning object) the conservation of angular momentum causes the earths rotating to slow down thus days would be longer.

How long it would be increased can be determined by using the equation for calculating angular momentum L = (4/5TH)re where r is the radius of the sphere(the radius of the earth is currently 6,367,mom but would be increased to 6367530m if the polar ice caps melting caused sea levels to rise mom), T equals the length of a day which is approximately 86400 seconds.Using these numbers the new length of a day would be calculated by ululating 63675302 (the estimated new radius of earth after the melting of the polar ice caps) by 86400 (approximate length of current earth day in seconds) and dividing this number by 63675002 (the current radius of the earth) which equals 86400. 8 an increase in the length of the day by 0. 8 seconds.

A can of diet soda floats in water, whereas a can of regular soda sinks.Explain this phenomenon in terms of density and in terms of weight versus buoyant force. Support your answer. If the can of diet soda floats it must be less dense then can of regular soda. This is most likely due to the amount or density of the sweetener used.

The artificial sweetener used in diet soda is either less dense than sugar or sweeter than sugar requiring less of it to be used. In order for the diet soda can to float the wrWrightf the can must be less than the buoyant force that would act on it if it was totally submerged. Therefore, the weight of the can is equal to the buoyant force acting on it aucausingt to float.In the case of the can of regular soda the weight of the can is greater than the buoyant force that is acting on it when it is totally submerged causing it to sink. 2.

A 10 kgkegron ball is dropped onto the pavement from a height of 100 m. If half of the heat generated goes into warming the ball, find the temperature increase of the ball. The specific heat capacity of the ball is 450 J/kgcocoExplain why the answer is the same for a ball of any mass.

First we have to calculate the work done by gravity on the ball. This is calculated by multiplying 1 OkOakmass of the ball) by 10mom2soacceleration due o gravity) by 10momdistance traveled).This gives us a work of gravity of 10,000 m2mm2sohich equals 10000 J/kgkegHalf this energy is used to heating the ball so we will use 5,00JOYgkego calculate the change in temperature. Next we need to figure out the heat energy of the ball. This is done by multiplying 450 J/kgkegCcothe heat capacity of Iron) by the 10kegass of the ball) by change in temperature (what we are trying to calculate). So or oror. 11?AT.

This will remain the same regardless of the mass of the ball because the mass is in both sides of the equation therefore, they cancel each other out.
