What are the difference between conductor and insulator? ​

Physics
1 answer:
Anvisha [2.4K]3 years ago
5 0

Answer:

  • A conductor allows energy e.g. electric charge or heat to pass through it easily. While an insulator does not let electric current or heat to travel through it.
  • Insulators have strong molecular bonds. While molecular bonds are very weak in conductors.
  • Insulators have very low conductivity. While in conductors, it is very high.
  • Insulators have a very high resistance and therefore the electrons are held together very firmly. The conductors, on the other hand, have a very low resistance.
  • Insulators do not have any electric field, neither inside nor on the surface. While in conductors, it is found on the surface and continues to be zero in the inner part of the conductor.

Illusion [34]
Boyle's law is a gas law, stating that the pressure and volume of a gas have an inverse relationship, when temperature is held constant. If volume increases, then pressure decreases and vice versa, when temperature is held constant.

A 0.14-kg baseball is moving at 41 m/s. A 0.058-kg tennis ball is moving at 67 m/s. Which of the two balls has higher kinetic en
lbvjy [14]

Answer:

The kinetic energy of tennis ball is higher than that of baseball.

Explanation:

mass of baseball m_{b} = 0.14 kg

velocity of baseball v_{b} = 41 m/s

mass of tennis ball m_{t}  = 0.058 kg

velocity of tennis ball v_{t}= 67 m/s

To find: the kinetic energy of baseball KE_{b} and tennis ball KE_{t}

We know that the kinetic energy is given by the equation,

KE = \frac{mv^{2}}{2}

the kinetic energy of baseball KE_{b} = \frac{m_{b}v_{b}  ^{2}}{2}

                                                           = \frac{0.14 * 41^{2}}{2}

                                                           = 117.67 J

the kinetic energy of tennis ball KE_{t} = \frac{m_{t}v_{t}  ^{2}}{2}

                                                             = \frac{0.058 * 67^{2}}{2}

                                                             = 130.181 J

Hence KE_{t} > KE_{b}, the kinetic energy of tennis ball is higher than that of baseball

Parallel rays of monochromatic light with wavelength 583 nm illuminate two identical slits and produce an interference pattern o
romanna [79]

Answer:

  I = 2.18 10⁻⁴ W / m²

Explanation:

The two-slit interference pattern is described by the expression for constructive interference.

             d sin θ = m λ

If we also want to know the distribution of intensities we must perform the su of the electric field of the two waves, and find the intensity as the square of the velvet field, obtaining the expression

              I = I_max cos² ((π d /λ L) y)

where d is the separation of the slits, λ  the wavelength, L the distance to the screen e and the separation of the interference line with respect to the central maximum

 

let's reduce the magnitudes to the SI system

λ  = 583 nm = 583 10⁻⁹ m

L = 75.0 cm = 75.0 10⁻² m

d = 0.640 mm = 0.640 10⁻³ m

y = 0.900 mm = 0.900 10⁻³ m

let's calculate the intensity of this line

        I = 5 10⁻⁴ cos² ((π 0.640 10⁻³ /583 10⁻⁹ 0.75 10⁻²) 0.900 10⁻³)

        I = 5 10⁻⁴ cos2 (413.84)

         I = 5 10⁻⁴ 0.435

        I = 2.18 10⁻⁴ W / m²
