A piston, A, as shown below, has a diameter of 0.54 cm. A second piston, B has a diameter of 3.8 cm. Determine the force, F, necessary to support the 500.0 N weight in the absence of friction.

You do not need to use E=mc^2. Calculate the sum of mass of products in (u) and mass of reactants in (u). Then, mass of product minus mass of reactants. It will be negative, which means energy is released (exorgenic rxn)and Q will be positive. Now, to fin...

The final answer will be 2.80 MeV On the left side of quation is 11.0216024 (u), on the right side 11.0186074. So,11.0186074-11.0216024=-0.0029954 (we use positiv value for Q).Q= 0.0029954 u *931.5 MeV/u = 2.79 MeV

RBC's of type O do not have surfarce antigens; in the blood of this individual will be naturally occuring antibodies to A type antigens on RBC's of the donor. Reaction between anti-A antobodies with A antigens in the donor's blood will cause type II hyper...
