Answer:

the speed at which a hummingbird flies

Explanation:

Biology is the science responsible for studying life and the interactions between living beings. When we say that biology is responsible for the study of life, we are referring to living beings and their metabolic, reproductive and evolutionary processes, in addition to studying the construction and influences of these habitats in general. Thus, we can affirm that biology allows the study of:

  • The relationship between fungi and trees
  • The distribution of sand on the ocean floor
  • The way chemicals act in the stomach.

However, biology is not the science responsible for studying the speed with which a hummingbird flies. Although the beixa-flor is a living being, speed is a variable studied by physics, which is another science.

¿Qué importancia tiene el saber sobre las propiedades de la energía?
user100 [1]
En qué medida todos los objetos con los que interactuamos (comida, bebida, mesas, sillas, coches, ordenadores ...) están hechos de materia: es importante conocer las propiedades que encontramos en nuestra vida diaria para poder interactuar con ellos . es decir. por lo que no tratamos de beber sólidos, necesitamos conocer la propiedad del material "fase" como sólido líquido o gas y cómo diferenciarlos. Eso es solo un ejemplo muy simple. La gente siempre se quema, por ejemplo, cuando era evitable, porque no entendió alguna propiedad de la materia que se enseña en la escuela. Saber cómo surgen las diversas propiedades de la materia es importante porque no podemos predecir qué propiedades serán importantes en el futuro y así es como se puede anticipar de manera más confiable cómo se comportarán los objetos. De esa manera, estará mejor equipado para lidiar con asuntos que no haya encontrado anteriormente. Es por eso que se enseñan propiedades que es poco probable que encuentre en su vida diaria, al menos no directamente. Además, el hecho de que nunca se encuentre con una propiedad en particular no significa que no sea importante conocerla. Otras personas ... con las que interactúas, es decir. es posible que tenga que votar sobre algo que se base en una explicación basada. Además, yo diría que nuestras vidas son más ricas si sabemos lo que realmente está sucediendo. 21K vistas Ver votos positivos. -Simon bridge

HELP PLEASE IM STUCK ON THESE QUESTIONS
Diano4ka-milaya [45]

Answer:

a = 10 m/s²

F = 2000 N

m = 8.57 Kg

Explanation:

1) What is the acceleration of a 40 kg object pushed with a force of 400 N?

Acceleration of object = ?

Mass of object = 40 Kg

Force on object = 400 N

Solution:

Formula:

F = ma

by putting values,

400 N = 40 Kg × a

a = 400 N/ 40 Kg   ( N = Kg.m /s²)

a = 10 m/s²

2) What is the force on an 800 kg rock being thrown at 2.5 m/s2?

Acceleration of object = 2.5 m/s²

Mass of object = 800 Kg

Force on object = ?

Solution:

Formula:

F = ma

by putting values,

F = 800 Kg × 2.5 m/s²

F = 2000 Kg. m/s²  ( N = Kg.m /s²)

F = 2000 N

3) What is the mass of a ball being rolled at 3.5 m/s2 from a 30 N force?

Acceleration of object = 3.5 m/s²

Mass of object = ?

Force on object = 30 N

Solution:

Formula:

F = ma

by putting values,

30 N = m ×  3.5 m/s²

m = 30 N / 3.5 m/s²   ( N = Kg.m /s²)

m = 8.57 Kg
