According to Kepler third law the relation between orbital period and radio of matter in the Galaxy is given by
Where,
a = Radius of start orbit
p = Orbital Period
M = Total mass in a sphere of radius centered on galactic center
Our values are given as
Replacing we have,
Therefore the mass of the galaxy within the sun's orbit is 108Billion the mass of the sun.
Answer:
The gravity model predicts that the optimal location of a service is directly related to the population of people in a given location and inversely related to the distance people must cover in search of it.
An optimal service is directly dependent on the size of people in that given area . The larger the people the larger the customers and vice versa.
If the place is far then less people will patronize because people won’t be willing to go through such stress to get such goods or services.
Answer and Explanation:
DE BROGLIE 'S HYPOTHESIS :
- According to De broglie the matter have dual nature it can behave as particle as well as wave
- According to this hypothesis all matter have wave like property and having wavelength.
- The de broglie wavelength is given by
here h is plank's constant and P is momentum - This hypothesis determines the probability of finding the object at a give point
