Answer: 
1.85
Explanation: Estimate the total mass of a binary system is done by a reformulation of <em>Kepler's Third Law</em>, which states that the square of the period of a planet's orbit is proportional to the cube of its semimajor axis, i.e.:
where
a is semimajor axis in astronomical units (AU);
P is period measured in years;
is total mass of the two-stars system;
For the two stars faraway in the Milky Way:
1 year is equivalent of 365 days, so period in years:
P = 1.63 years
Calculating total mass:
1.85
<u>The total mass of the two-object system is 1.85 mass units.</u>
Answer:
The difference between a molecule and a compound is that a compound is made up of atoms from different elements.
Molten Mattet Seeps through the crust and forms new land.
Answer:
Induced emf, 
Explanation:
We have,
Number of turns in the coil, N = 40
Radius of coil, r = 3 cm = 0.03 m
The field increases from 0 to 0.75 T at a constant rate in a time interval of 225 s.
It is required to find the magnitude of the induced emf in the coil if the field is perpendicular to the plane of the coil. The induced emf is given by :
, is magnetic flux
So, the magnitude of induced emf is 
.
A substance which allows the un-interrupted flow of electric current is called an electric conductor
