Kepler's laws follow which law discovered by sir isaac newton?

a. universal laws of attraction
b. universal gravitational law
c. universal law of force
d. universal law of friction

B. Universal Gravitational Law

Explanation:

As we know that Kepler gives three laws regarding the planetary motion of all planets around the sun

All his laws are derived from the basic Theory of law of attraction by gravitation.

Universal law of attraction given by Sir Issac Newton says that if two masses are placed at some distance from each other then the net force between two masses is given as

here we know that

= masses of two objects

= distance between two objects

it is b. absorbs thermal energy

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
