Hi guys, now in this problem, we have this sun and this is earth and the radius of the what i mean the distance between the sun and the earth is given to us 1 .5 times 10 to 10 to 1 .5 m .m .m .m .m.
00:12
And the mass of the earth is also given to us 5 .97 times 10 to 24 kc.
00:18
So in this case we need to find out a linear momentum.
00:21
This linear momentum, p is equal to mv.
00:25
Now i know the mass of the earth.
00:30
But i don't know what is the velocity of the earth in order to find out velocity as in order to velocity is at 2 i r divide by d this is a distance between sun and the earth and this is time period for taking one orbit around the sun now how much time it will take to sun it will take to earth to take one orbit around the sun which is what 365 days so this is 2xr, this is 2x, let me write all this value.
01:07
If i'm writing this, i know what is v.
01:09
So let me write this value in this p, this is 2xr, divide by t...
