Cual es la densidad de un cubo de madera que tiene una masa de 210 gramos y cuatro lados?

Answers

Answer 1

A densidade de amostra, tanto para sólidos quanto para líquidos, é uma medida da quantidade de massa presente em um determinado volume. Ela é frequentemente expressa em unidades como gramas por centímetro cúbico (g/cm³) ou quilogramas por metro cúbico (kg/m³).

No contexto de amostras sólidas, a densidade pode fornecer informações sobre a composição, estrutura e compactação do material. Por exemplo, a densidade de um sólido pode indicar a presença de impurezas, a porosidade do material ou até mesmo ajudar a identificar o tipo de substância presente. A densidade também é um parâmetro importante em muitos cálculos e processos científicos, como na determinação da concentração de soluções, em análises de materiais e em estudos de densidade de populações de organismos.

Quanto às amostras líquidas, a densidade desempenha um papel fundamental na caracterização de líquidos e soluções. A densidade pode ser usada para distinguir diferentes líquidos com base em suas propriedades físicas, auxiliar na determinação da pureza de uma substância líquida e até mesmo fornecer informações sobre a concentração de soluções. A densidade também é um fator importante na flutuabilidade de objetos em líquidos e é usada em muitas aplicações práticas, como na indústria alimentícia, na indústria química e na exploração de petróleo.

Em resumo, a densidade de amostras sólidas e líquidas fornece informações valiosas sobre a composição, estrutura e propriedades físicas dos materiais. É uma medida amplamente utilizada em diversos campos científicos e industriais, contribuindo para a compreensão e manipulação de substâncias sólidas e líquidas em várias aplicações.

one of the main reasons protestant criticisms of the church did not find support in spain was because

Answers

One of the main reasons protestant criticisms of the church did not find support in spain was because humanist ideas were incorporated into Catholic practices in Spain. So, option C is the correct one.

Catholic practices in Spain were heavily influenced by humanist ideas during the Renaissance period. While there may have been fewer people who could read Latin in Spain compared to Northern Europe, this would not be the main reason for the lack of support for Protestant criticisms.

This integration of humanist ideas allowed the Catholic Church in Spain to address some of the concerns raised by Protestant reformers, ultimately preventing the spread of Protestantism in the country.

Furthermore, while Spain was certainly preoccupied with colonizing the Americas, this would also not be the main reason for the lack of support for Protestant criticisms.

Therefore, the correct option is C.

Complete Question

One of the main reasons protestant criticisms of the church did not find support in spain was because

a) there were fewer people who could read Latin in Spain than in northern Europe

b) most Spaniards were preoccupied with colonizing the Americas

29 Halla dos números consecutivos tales que, añadiendo al mayor
la mitad del menor, el resultado excede en 13 unidades a la suma
de la quinta parte del menor con la onceava parte del mayor.

Answers

Answer:

Los dos números son:

10 y 11

Explanation:

a = primer número (menor)

a+1 = consecutivo   (mayor)

entonces:

a+1 + a/2 = a/5 + (a+1)/11 + 13

a + a/2 - a/5 - (a+1)/11 = 13-1

110a/110 + 55a/110 - 22a/110 - 10(a+1)/110 = 1320/110

110a + 55a - 22a - 10(a+1) = 1320

165a - 22a - 10*a - 10*1 = 1320

143a - 10a - 10 = 1320

133a = 1320 + 10

133a = 1330

a = 1330/133

a = 10

a + 1 = 11

Comprobación:

11 + 10/2 = 10/5 + 11/11 + 13

11 + 5 = 2 + 1 + 13 = 16
