Coulomb’s law is an equation that relates the electrostatic force between two objects to their distance and charge. In activity A, you found that the electrostatic force between two objects is proportional to the product of their charges. Combine that with what you have learned in this activity to complete Coulomb’s law below. (Hint: In the equation, k is a constant.) Please help me with this! I've been trying to solve this for days and it's due today!

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?

How are series and parallel circuits simililar? both have multiple paths for electrons to travel. both require resistors in their circuits. both require a switch to complete the circuit. both have at least one path for electrons to travel.
