Not sure how to show crisscross method
Make sure adding the charges together=0 and multiply the elements when necessary to balance charge
The decay of a radioactive isotope can be predicted using the formula: A = Ao[2^(-t/T_0.5)] where A is the amount after time t, Ao is the original amount and T_0.5 is the half-life. Using the equation and the given values, 0.888 g of the sample will remain after 72 minutes.
Answer:
A long uniformly charged wire has charge density λ=0.16μλ=0.16μC/m.
Answer: Flow rate is inversely proportional to viscosity.
Explanation: The relation is called Poiseuille's law, which describes the smooth flow of a fluid along a tube.
