Uncertainty of a Hydrogen Atom from the ground-state energy can be estimated using the Heisenberg's uncertainty principle. Assuming the size of a hydrogen atom is approximately 0.1 nm, prove that the ground state energy of a Hydrogen atom is approximately leV inside a one-dimensional box of length L=0.Inm.

the answer is b & c i believe : )

the population of unionid mussels in the hudson river decreased after zebra mussels were introduced. zebra mussels, a nonnative species, competed with the unionid mussels for food. the zebra mussels were able to outcompete the unionid mussels, allowing the zebra mussel population to increase dramatically over six years. the unionid mussel population decreased due to a lack of food.

hope this :
