D. At a construction site, a crane lifts a steel beam with a mass of 330 kg. While it is being lifted, the steel beam is at a height of 20 m and is moving with a speed of 1.3
m/s. What is the total mechanical energy of the steel beam at this moment?

c the car's velocity increases constantly over time.

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

explanation:

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
