Dos cuerpos de 1 kg y 2 kg descansan sobre un plano horizontal y un plano inclinado 30°, respectivamente, unidos por una cuerda que pasa a través de una polea. Halla: a) La tensión de la
cuerda y la aceleración del sistema suponiendo que no hay rozamiento. b) Haz el mismo cálculo
suponiendo que en los dos planos existe un coeficiente de rozamiento cinético μK = 0,34.
Sol: 3,27 N; 3,6 N.

so easy. just google the electromagnetic waves and it’ll pop up.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer

the inner core.

good luck: )
