Answer:
The point on the rim
Explanation:
All the points on the disk travels at the same angular speed 
, since they cover the same angular displacement in the same time. Instead, the tangential speed of a point on the disk is given by
where
is the angular speed
r is the distance of the point from the centre of the disk
As we can see, the tangential speed is directly proportional to the distance from the centre: so the point on the rim, having a larger r than the point halway between the rim and the axis, will have a larger tangential speed, and therefore will travel a greater distance in a given time.
As per Weins displacement law the wavelength of light for which we get the peak of the graph is always inversely proportional to the temperature.
So we can say
So here if temperature becomes more cool then wavelength will increase
here we know that
It means the hottest star out of all three is star 3
and coolest star is star 1
now if we star 2 becomes cooler then it means its temperature will go near to star 1 and hence it will more look like to star 1.
So correct answer is
it will look more like Star 1
That statement is as false as false can be.
Roughly 78% of the Earth's surface is covered by water,
and Hydrogen is a major component of water.
On the surface of the Earth, you really have to try hard
to be far away from a cheap source of Hydrogen.
The momentum would be 9 kg
