Answer:
What does this mean i don't get you??
Separation by density filtration because lead slightly interacts with magnets also.
As the distance from the Sun increases the time to orbit the Sun increases. <em>(a)</em>
Examples:
-- Nearest planet to the sun: Mercury. Time to orbit the sun: 88 days
-- 3rd planet from the sun: Earth. Time to orbit the sun: 1 year
-- 5th planet from the sun: Jupiter. Time to orbit the sun: 12 years
-- 9th closest object to the sun: Pluto. Time to orbit the sun: 248 years
Another pair of examples:
-- Object in a near Earth orbit: International Space Station
Time to orbit the Earth: 90 minutes
-- Object in a far Earth orbit: the Moon
Time to orbit the Earth: 27.3 days
The reason for all of this is: Two things about orbits.
1). The larger the orbit is, the farther the object has to travel around it.
2). The farther out the object is, the slower it travels in its orbit.
This is simply the way gravity works.

Answer:
3 × 10⁴
Explanation:
We are given two numbers,
and 
We have to divide n₁ by n₂. We know that,

Here, n = -5 and m = -9
So on dividing we get :

Hence, on dividing n₁ by n₂ obtained number is 3 × 10⁴.
