Answer:

4. B) 69N

5. B) 7.2kg

Explanation:

Dados los siguientes parámetros;

Masa = 7kg

Peso = 71N

La aceleración debida a la gravedad es igual a 9.8m/s².

a. Para determinar el peso de la siguiente masa;

Matemáticamente, el peso viene dada por la fórmula;

Peso = masa * aceleración debida a la gravedad

Peso = 7 * 9.8

Peso = 68.6 ≈ 69 Newton.

b. ¿Cuál es la masa sobre la tierra de un objeto que pesa.

Peso = masa * aceleración debida a la gravedad

71 = masa * 9.8

Masa = 71/9.8

Masa = 7.2 Kilograms.

From the average distance of one of jupiter's moons to jupiter and its orbital period around jupiter, we can determine:

den301095 [7]

Answer: Jupiter's mass

Explanation:

From Kepler's third law:

$T^2=\frac{4\pi^2}{GM}a^3$

where T is the orbital period of a satellite, a is the average distance of the satellite from the Planet, M is the mass of the planet, G is the gravitational constant.

If the average distance of one of Jupiter's moons to Jupiter and its orbital period around Jupiter is given then mass of the Jupiter can be found:

$\Rightarrow M_J=\frac{4\pi^2}{GT_m^2}a_m^3$
