We are asked to solve for the arc length of the intercepted arc and the formula is shown below:
Arc length = 2*pi*r(central angle/360°)
r = 5 feet
central angle = 10°
Solving for the arc length, we have:
Arc length = 2*3.14*5 (10/360)
Arc length = 0.872 feet
The arc length is 0.872 feet.
Kepler stated three laws of planetary motion.
First law states that the pathway of a planet is an ellipse with the Sun at one of the foci.
Second law states that an imaginary line joining the Sun and a planet sweeps out equal areas during equal lengths of time.
Third law states that the square of the period of the orbit of a planet is directly proportional to the cube of the length of the distance from the Sun.
Therefore, the answer is that Kepler's second law of planetary motion states that planets cover the same area during equal time periods.

Answer:
AlN has highest melting point among given.
Explanation:
As per ionic model, ionic compounds are held together by electrostatic force. The ionic compound having strong electrostatic force will have high melting point.
Electrostatic force is proportional to charge and size of constituent ions.
In case of MgO
Charge on Mg = +2
Charge on O = -2
In case of LiF
Charge on Li = +1
Charge on F = -1
In case of AlN
Charge on Al = +3
Charge on N = -3
In case of RbF
Charge on Rb = +1
Charge on F = -1
In case of CaS
Charge on Ca = +2
Charge on S = -2
As magnitude of electrostatic force is highest in AlN, therefor, it has highest melting point.
