Fe=(9.0*10^9 N*m^2/C^2)(-32*10^-12C^2)/ (9*10^4 m^2)​

The sun generates both mechanical and electromagnetic waves. which statement about those wave is true?

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?

Simple machines can a. increase force only b. decrease force only c. increase or decrease force
