Answer:
La distancia entre los dos cuerpos es aproximadamente 1.269 milímetros.
Explanation:
Asumamos que ambos cuerpos son partículas, la fuerza de atracción (
), en newtons, entre ambos cuerpos se define mediante la Ley de Newton de la Gravitación Universal, cuya ecuación es:
(1)
Donde:
- Constante de la gravitación universal, en metros cúbicos por kilogramo-segundo cuadrado.
- Masas de los cuerpos, en kilogramos.
- Distancia entre los cuerpos, en metros.
Si sabemos que
,
,
y
, entonces la distancia entre los dos cuerpos es:

Es decir, la distancia entre los dos cuerpos es aproximadamente 1.269 milímetros.
The answer is b) false. Stars are mainly classified by their spectra (the elements they absorb) and their temperature.
Answer and Explanation:
The estimation of the mass of the objects is as follows
Given that
The mass of an apple is about 100 g
Just like that, we do some estimation of different objects
A dime is around 1 g
A smartphone is about 100 g
An adult male is approx 100 kg
A college physics textbook is around 1 kg
A ripe banana is around 100 g
A small car is around 1,000 kg
