Suppose that 3 j of work is needed to stretch a spring from its natural length of 36 cm to a length of 46 cm. (a) how much work is needed to stretch the spring from 40 cm to 42 cm? (round your answer to two decimal places.) 0.12 incorrect: your answer is incorrect. j (b) how far beyond its natural length will a force of 25 n keep the spring stretched? (round your answer one decimal place.) cm

In a given chemical reaction, the energy of the products is greater than the energy of the reactants. which statement is true for this reaction?

Will give brainliest! which statement best describes the difference between strong nuclear forces and weak nuclear forces? weak nuclear forces are involved when certain types of atoms break down. strong nuclear forces are responsible for holding atoms' nucleus together. weak nuclear forces hold bonds between atoms together. strong nuclear forces hold together the nucleus of an atom. strong nuclear bonds prevent atoms from falling apart. weak nuclear bonds prevent compounds from falling apart. strong nuclear forces are involved in breaking electrons from their shells. weak nuclear forces hold protons in the nucleus.

The nuclear potential that binds protons and neutrons in the nucleus of an atom is often approximated by a square well. imagine a proton conned in an innite square well of length 105 nm, a typical nuclear diameter. calculate the wavelength and energy associated with the photon that is emitted when the proton undergoes a transition from the rst excited state (n 2) to the ground state (n 1). in what region of the electromagnetic spectrum does this wavelength belong?
