How do humans impact a watershed? Building dams and rerouting rivers are two examples of ways humans directly impact water in watersheds. Humans also use water as a resource, drawing from watersheds for our drinking water. This does not have to be a negative impact, as water usage can be monitored so that it is […]
What is the first possible excited state?
What is the first possible excited state? stands for singlet corresponding to the plus sign. Thus we have a large effective spin-spin interaction entirely due to electron repulsion. There is a large difference in energy between the singlet and triplet states. What is the value of energy for the first excited state of hydrogen atom? […]

How do you find the current of a coil?
How do you find the current of a coil? To determine the current flow in the wire, first find the inductive reactance of the coil. The inductive reactance equals 6.28 times 60 hertz times 0.3 henries which equals 113.1 ohms. Now use Ohm’s Law and divide 120 volts by 113.1 ohms which equals 1.06 amps. […]

How does water have potential energy?
How does water have potential energy? The water behind a hydroelectric dam stores gravitational potential energy since it is at a higher level than the water on the other side of the dam. As the water falls, this potential energy is converted into kinetic energy, which turns turbines to generate electricity. Does water have a […]
