Explain the difference between a conductor and an insulator. Give two examples of each.
docker41 [41]
There are different kinds of conductors, most notably electrical and thermal conductors. But they are often inclusive of each other (electrical conductors are typically good thermal conductors). A conductor transmits something through its body with high efficiency while an insulator does not transmit very well. In the case of electricity, a conductor transmits electrical energy between two points while an insulator blocks the flow of electricity. Two examples of conductors are copper and silver. Two examples of insulators are wood and styrofoam.

A 0.900 kg block is attached to a spring with spring constant 14.5 N/m . While the block is sitting at rest, a student hits it w
olga55 [171]

Answer:

1. A=0.0847\ m

2. v=0.050\ m.s^{-1}

Explanation:

Given:

  • mass of block, m=0.9\ kg
  • spring constant, k=14.5\ N.m^{-1}
  • maximum velocity of block, v_m=34\ cm.s^{-1}

1.

<u>We know from the energy of oscillating spring:</u>

E=\frac{1}{2}.k.A^2= \frac{1}{2}.m.v_m^2

\frac{1}{2}\times 14.5\times A^2=\frac{1}{2}\times 0.9\times 0.34^2

A=0.0847\ m

2.

Now, given that:

instantaneous position, x=0.15\times A=0.0127\ m

we find angular speed,

\omega=\sqrt{\frac{k}{m} }

\omega=\sqrt{\frac{14.5}{0.9} }

\omega=4.013\ rad.s^{-1}

So we have

v=x.\omega

v=0.0127\times 4.013

v=0.051\ m.s^{-1}
