Consider a gas of O2 molecules (weight 32 g/mol). The temperature of the gas is such that rotational and translational degrees of freedom are active. When the rotational energy is increased by 6.90e-21 J per molecule by adding heat, by how much is the typical translational energy per molecule increased

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 :
