Two ball bearings of mass m each moving in opposite directins with equal speed v collide head on with each other.predict the out

come of the collision considering them to be perfectly elastic

Yo sup??

since the collision is elastic therefore we can say that the two balls will then move in opposite direction.

If ball 1 was moving from east to west then after collision it will move from west to east

and if ball 2 was moving from west to east then it will start moving from east to west.

Hope this helps.

What characteristics of EM waves did you discover?
jarptica [38.1K]

The characteristics of electromagnetic waves typically represent as follows:

  • There are changes in the electric and magnetic fields simultaneously so that both fields have maximum and minimum values ​​at the same time and place.
  • The direction of the electric field and the magnetic field are perpendicular to each other. The direction of both is perpendicular to the direction of the wave propagation.
  • The shape of electromagnetic waves is transverse waves.
  • It has general wave characteristics like polarization, reflection, refraction, interference, and diffraction.
  • The amount of the electric field (E) is directly proportional to the magnitude of the magnetic field, with the relationship E = cB.
  • The universal constant of the velocity of electromagnetic waves in a vacuum is \boxed{ \ c = 3 \times 10^8 \ m/s. \ }
  • The speed at which electromagnetic waves propagate depends merely on the electrical and magnetic properties of the medium that it travels on.
  • Because electromagnetic waves do not contain an electric charge, they do not experience any possible deviation in the electric or magnetic fields.
<h3>Further explanation</h3>
  • Two physicists who contributed significantly to developing the concept of electromagnetic waves are Faraday and Maxwell around 1831-1864.
  • From the observations, Faraday suggested that changes in the magnetic field cause an electric charge to flow in the loop of wire, contributing in the emergence of an electric field.
  • Maxwell proposed a reverse process, which is a change in the electric field will generate a magnetic field.
  • As follows, according to Faraday's Law, changes in sinusoidal magnetic fields generate electric fields which also change sinusoidally.
  • Meantime, according to Maxwell's Hypothesis, changes in sinusoidal electric fields generate magnetic fields which also change sinusoidally.
  • Furthermore, there is a process of combining electric and magnetic fields that propagate in all directions called electromagnetic waves.

It is strong elastic and light .it is lutrous and easy to wash. so it become very popular for making clothes
Marrrta [24]

Answer:

Nylon fibres

Explanation:

Nylon fibres are synthetic polymers made of repeating units linked by amide links. It is a thermoplastic silky material which can be remoulded in any shape.

Nylon fibres have the property of strong elastic and light in weight that is why used for making ropes,  combat uniforms, and parachutes. Nylon Fibres are also lustrous and easy to wash so widely used in textile industry for making swimwear, track pants, shorts, and draperies.

Hence, the correct answer is "Nylon fibres".
