Can someone help me plz?? Research two natural and two artificial resources for radioactivity, make sure to include three things. 1) Is the product useful or dangerous? 2) What do use the products with or where they end up? 3) The amount of products released.

Current enters a circuit at a: 1.positive terminal 2.negative terminal 3.low potential side 4.resistor

Of is j/kg·k. if a 2.6 kg of isk to k,is ?

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
