Aneutral solid metal sphere of radius 0.1 m is at the origin, polarized by a point charge of 9 ✕ 10−8 c at location −0.6, 0, 0 m. at location 0, 0.08, 0 m, what is the electric field contributed by the polarization charges on the surface of the metal sphere?

What type of nuclear decay causes the atomic number of an element to increase by 1?

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?

What component of earth’s atmosphere exists entirely as a result of photosynthesis?
