Find a center of mass of a thin plate of density delta equals 5 bounded by the lines y equals x and x equals 0 and the parabola y equals 20 minus x squared in the first quadrant.

It is necessary to determine the specific heat of an unknown object. the mass of the object is 201.0g it is determined experimentally that it takes 15j to raise the temperature 10°c. what is the specific heat of the object? 3,020,000 j/kg ∙ k 1500 j/kg ∙ k 0.00130 j/kg ∙ k 7.46 j/kg ∙ k
