d Newton Found GRAVITY? • In 1665, the University of Cambridge temporarily closed due to an outbreak of the bubonic plague. As a result, Isaac Newton head to work from home. he USED this time to develop calculus and the theory of gravity. • Sir Issac Newton was only 23 years old when he discovered the law of gravity. • In fact, Newton does not discovered gravity; he only discovered that the gravity is universal. More to know –– Everything pulls on everything else in a simple way that involves only mass and distance. – Newton's law of Universal Gravitation STATES that every object attracts every other object with a force that for any TWO objects is directly proportional to the mass of each object. Hope it helps you dear.

ElectromagnetsAn electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets USUALLY consist of wire wound into a coil.Explanation:here is your ANSWER if you LIKE my answer please follow

The ATTACH themselves more at the of MAGNET .

our eyes has a tiny functional blind spot about the size of a PINHEAD. In this tiny area, where the optic nerve passes through the surface of the RETINA, there are no photoreceptors. Since there are no photoreceptor CELLS DETECTING light, it creates a blind spot.

a) Initial kinetic energy KE = 1/2 m1v12 + 1/2 m2v22 = joules. The following calculation expects you to enter a final velocity for mass m1 and then it calculates the final velocity of the other mass REQUIRED to conserve momentum and calculates the kinetic energy either gained or lost to make POSSIBLE such a collision.b) Newton's second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate. In the SIMPLEST case, a force applied to an object at rest causes it to accelerate in the direction of the FORCEC) Initial velocity 3 m/s. This velocity component will not be altered by normal acceleration. hence this component velocity after 4 s is 3 m/s.d) ACCORDING to the concept of kinetic energy of rolling & translation energy,hence,Total K.E of rolling body = 12I ω 2 + 12m v2 (V = R ω ) = 12 I ω 2 e

Materials that can be magnetized, which are also the ones that are strongly ATTRACTED to a magnet, are called ferromagnetic (or FERRIMAGNETIC). These include the ELEMENTS iron, nickel and COBALT and their alloys, some alloys of rare-earth metals, and some naturally occurring MINERALS such as lodestone.

PolesExplanation: POLES have the HIGHEST MAGNITUDE MAGNETIC ENERGY (#OrginalAnswer)

polesExplanation:A magnet , no matter how BIG or small, will ALWAYS have two POLES.

tion:Wavelength of red LIGHT is greater than that of violet light. And, refractive index of any light is inversely proportional to the wavelength. Therefore, refractive index of red light is less. ... THUS, when violet light is replaced with red light, ANGLE of MINIMU deviation decreases.

light travels in a straight LINE is CALLED RECTILINEAR PROPOGATION of light

ors don't ALLOW CURRENT to flow through it. Electric charges are absent in INSULATOR#HopeItHelps

true COMPASS can be used to FIND east west DIRECTION at any PLACE

Like poles repel each other and unlike poles attract each other.Thus, like poles repel and unlike poles attract each other. COMPLETE answer: Electrons in the ATOMS of any magnetic MATERIAL spin around the nucleus mainly in one direction.Hope it HELPS you
