Una cuerda horizontal se somete a una tensión de 500N. Su masa es de 0.3 kg y su longitud de 150 cm ,si se pone a vibrar con una amplitud de o,3 m halla : a. La densidad longitudinal b. La velocidad de la onda c. La funcion de onda si la frecuencia es 25s-1

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

(b) which contains higher levels of vitamin b, oranges or spinach?

explanation:

you can eliminate a, c, and d because they are questions based on opinions.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
