Answer:
The value is 
Explanation:
From the question we are told that
The orbital period is 
Generally for the centripetal force acting one of the stars will be equal to the gravitational force between the stars and this can be mathematically represented as
=> 
Here m represents the mass of each star given that they have same mass and this equal to the mass of the sun whose value is
d(2 * r) is the diameter of the orbit which is distance between each star
r is the radius of the orbit
G is the gravitational constant with value 
v is the velocity of the stars which can be mathematically represented as
So
=> ![r =[ \frac{Gm T^2}{16 \pi ^2} ]^{\frac{1}{3} }](https://tex.z-dn.net/?f=r%20%3D%5B%20%20%5Cfrac%7BGm%20T%5E2%7D%7B16%20%5Cpi%20%5E2%7D%20%5D%5E%7B%5Cfrac%7B1%7D%7B3%7D%20%7D)
=> ![r = [\frac{6.67 *10^{-11} * (1.989 *10^{30}) * 2704320^2}{16 * (3.142)^2} ]^{\frac{1}{3} }](https://tex.z-dn.net/?f=r%20%3D%20%20%5B%5Cfrac%7B6.67%20%2A10%5E%7B-11%7D%20%2A%20%281.989%20%2A10%5E%7B30%7D%29%20%2A%202704320%5E2%7D%7B16%20%2A%20%283.142%29%5E2%7D%20%5D%5E%7B%5Cfrac%7B1%7D%7B3%7D%20%7D)
=> 
Generally the distance between the star is
=> 
=>
Answer:
The value is 
Explanation:
From the question we are told that
The power rating of the bulb is 
The frequency is 
The percentage of the input power that is emitted as visible light is 
Generally the amount of power emitted as visible light is mathematically represented as
=> 
=> 
Generally the amount of energy emitted as light is mathematically represented as
Here n is the number of photon , h is the Planks constant with value 
Generally this power emitted as visible light is mathematically represented as
=> 
=> 
=> 
=>
Answer:It shows the size of the range of the moisture contents at which the soil remains plastic. In general, the plasticity index depends only on the amount of clay present. It indicates the fineness of the soil and its capacity to change shape without altering its volume.
Answer:
Explanation:
Unstable nucleus tends to emit small particles of matter(alpha or beta particles) with an attendant emission of electromagnetic radiation and some amount of energy.
For every atomic nucleus, there is a specific neutron/proton ratio which ensures stability of the nucleus.
Any nucleus with a neutron/proton combination different from its stability ratio (i.e either too many neutrons or too many protons) will be unstable and split.
The will emit some small particles and radiations until they become stable.
