Assuming that the bohr model is valid, what is the kinetic energy of a photoelectron liberated by a photon with a the given wavelength from a state with given z and n

The material that keeps its new shape after it is stretched is called?

This is for my 8th grade science class, i really don’t understand. can someone me? , lol.

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )
