Un ascensor de masa 495 kg sube a lo largo de 4 pisos (cada piso tiene una altura de 1,2 m) con una aceleración de 0,73 m/s2. Sabiendo que la fuerza de roce en el ascensor al subir es 1350 N. Calcular el trabajo total y la potencia realizada sobre el ascensor para subir los cuatro pisos, si tarda 24 s.

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
