Answer:
Magnetic field, B = 0.199 T
Explanation:
It is given that,
Radius of circular loop, r = 11.7 cm = 0.117 m
Magnetic flux through the loop, 
The magnetic flux linked through the loop is :
Here, 
or
B = 0.199 T
So, the strength of the magnetic field is 0.199 T. Hence, this is the required solution.
Answer:
A sloping surface separating air masses that differ in temperature and moisture content is called a front.
Answer:
Factors determining the state of substances
* Inter molecular force : substances having strong intermolecular force will be solid and substance with weak inter molecular force will be gas.
* Nature of chemical bond:
Ionic compounds are generally solid in nature because of strong intermolecular force.
Polar covalent compounds may be solid or liquid
Non polar covalent compounds generally gas
* Electro negativity difference: greater the electronegativity difference, greater will be the intermolecular force.
