Explanation:

The quantity at which the speed of formation of the star depends is called the "star formation rate".
Astronomers estimate that in our Galaxy the star formation rate is about 3 solar masses per year
According to "solar mass per year" the mass of interstellar gas and dust related to about 3 times the mass of the Sun goes into stars each year).
However, the whole of the mass doesn't necessarily go in the formation of 1 star.

Answer:

see explanation

Explanation:

There is an increasing demand for materials and natural resources from a growing global population, especially those in more economically developed countries. The world's resources are being used up more quickly. The consumption of resources is spread unequally between MEDCs (more economically developed countries), who use more resources, and LEDCs (less economically developed countries), who use less.

The gap between the rich and poor is more evident when the resources are shared so unevenly and unfairly and natural resources like materials and natural energy cannot reach the demand of the people which can have consequences and be very difficult to manage. Having a lack of these materials in a country can result in prices going up for them, and the industry could be harder to work in because of a lack of materials.

Here when car in front of us applied brakes then it is slowing down due to frictional force on it

So here we can say that friction force on the car front of our car is given as

$F_f = \mu m g$
