Earth is 149.6 million meters from the Sun and takes 365 days to make one complete revolution around the Sun. Mars is 227.9 million meters from the Sun and has an orbital period of 687 days. What is the ratio of Earth’s centripetal acceleration to Mars’s centripetal acceleration

Explanation:

The distance of Earth from the Sun is and of Mars from the Sun is . Let assume that both planets have circular orbits. The centripetal accelaration can be found by using the following expression:

Since planet has translation at constant speed, this formula is applied to compute corresponding speeds:

Earth:

Mars:

Now, centripetal accelarations can be found:

Earth:

Mars:

The ratio of Earth's centripetal acceleration to Mars's centripetal acceleration is:

the largest known star in the universe is uy scuti, a hypergiant with a radius around 1,700 times larger than the sun.jul 26, 2018

explanation:

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
