As you know, the oceans cover most of the earth, and contain a huge amount of resources. protecting these resources is one reason to try and prevent the pollution of the ocean. direct pollution into the ocean, such as trash dumping or chemical spillage, must be dealt with. indirect pollution via the that drains into an ocean must be considered as well. a) aquifer b) bay c) pipe d) watershed

What is the most useful equation for electric power?

Exercise 2. find the wavelength of a photon emitted when an electron jumps from the n = 3 energy level down to the n = 2 energy level. where is this photon in the electromagnetic spectrum?

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
