The innermost satellite of jupiter orbits the planet with a radius of 422 × 103 km and a period of 1.77 days. what is the mass o
FinnZ [79.3K]

The mass of Jupitar is obtained from the calculations as 5.8 * 10^-14 Kg.

<h3>What is the mass of Jupitar?</h3>

There are nine planets in the solar system and the sun lies at the enter of our solar system. This is the heliocentric model of the solar system.

Given that;

T^2 = GMr^3/4π

T = period

G = gravitational constant

r = radius

M = mass of Jupitar

Now;

1 day = 86400 seconds

1.77 days = 1.77 days *  86400 seconds/1 day

= 152928 seconds

Making M the subject of the formula;

M =4πT^2/Gr^3

M = 4 * 3.142 * (152928)^2/6.67 × 10^-11 * (422 × 10^9)^3

M = 2.9 * 10^11/5.0 * 10^24

M = 5.8 * 10^-14 Kg

In designing structures in an earthquake-prone region, how should the natural frequencies of oscillation of a structure relate t
Genrish500 [490]

Answer:

Natural frequencies of oscillation and typical earthquake frequencies should be different.

Damping on the structure should be large.

Explanation:

The natural frequency of the structure must be different from the typical earthquake frequency, the more different the better. This is because if both frequencies were the same or similar there is a risk that the building will <u>resonate </u>and collapse.

As for the damping, it must have a high value. This so that the building resists earthquakes better and prevents it from moving dangerously, thus damping on the structure should be large.
