Imagine another solar system, with a star of the same mass as the Sun. Suppose a planet with a mass twice that of Earth (2 Earth
sashaice [31]

Answer:

Time period, T = 403.78 years

Explanation:

It is given that,

Orbital distance, a=1\ AU=1.496\times 10^{11}\ m

Mass of the Earth, m_e=5.972\times 10^{24}\ kg

Mass of the planet, m_p=2m_e=11.944\times 10^{24}\ kg

Let T is the orbital period of this planet. The Kepler's third law of motion gives the relation between the orbital period and the orbital distance.

T^2=\dfrac{4\pi^2}{Gm_p}a^3

T^2=\dfrac{4\pi^2}{6.67\times 10^{-11}\times 11.944\times 10^{24}}\times (1.496\times 10^{11})^3

T=1.28\times 10^{10}\ s

or

T = 403.78 years

So, the orbital period of this planet is 404 years. Hence, this is the required solution.

The mass of 29000 N elevator is
Lana71 [14]

<span>In this case we are given a force of 29,000 N. We know that the equation we  can use is:</span>

Force = mass * acceleration

 

However this is not just any type of force, because this is the weight of the elevator. So when the force is equal to weight, the acceleration acting is simply gravity. Therefore:

 

weight = mass * gravity

 

Calculating for mass:

mass = 29,000 N / (9.8 m/s^2)

<span>mass = 2,959.18 kg</span>
