When a carpet is beaten with a stick dust particles off ...why

Physics
1 answer:
Luda [366]3 years ago
7 0

Answer:

An object's inertia tends to resist any change in its state of rest or motion. If a carpet is beaten with a stick then the carpet begins to move. But, the particles of dust are trying to resist their state of rest.

PLEAASE HELP KE WITH THESE THREE YOULL GET POINTS
lozanna [386]

Answer:

  1. 0.0121
  2. 19.8387
  3. 2.2632

Explanation:

1.

\mathrm{The\:solution\:for\:Long\:Division\:of}\:\frac{0.01223}{1.01}\:\\\mathrm{is}\:0.0121

2.

\frac{\begin{matrix}\space\space&\textbf{\space\space}&\space\space&\space\space&\space\space&4&9&10\\ \space\space&\textbf{1}&9&.&8&\linethrough{5}&\linethrough{10}&\linethrough{0}\\ -&\textbf{0}&0&.&0&1&1&3\end{matrix}}{\begin{matrix}\space\space&\textbf{1}&9&.&8&3&8&7\end{matrix}}\\\\=19.8387

3.

0.1886\times 12\\\\Multiply\:without\:the\:decimal\:points,\:then\:put\:the\:decimal\:point\:in\:the\:answer\\1886\times\:12=22632\\\\0.1886\mathrm{\:has\:}4\mathrm{\:decimal\:places}\\12\mathrm{\:has\:}0\mathrm{\:decimal\:places}\\\\\mathrm{Therefore,\:the\:answer\:has\:}4\mathrm{\:decimal\:places}\\\\=2.2632

Total Internal Reflection
Firdavs [7]

Answer: The light beam will not diffract out of the prism.

Explanation: The angle the light is entering the prism is greater than the critical angle therefore total internal reflection will occur. Hope this helps :)

What would happen to Mars (orbiting around the Sun, obviously) if its tangential velocity was reduced
Rama09 [41]

Answer:

It would eventually crash into the Sun

Explanation:

If the mars is orbiting around the sun, the gravitational force of attraction is between the sun and mars supply the necessary force required for the centripetal motion.

If a planet is in centripetal motion, it is constantly falling towards the sun with the acceleration equal to the gravitational strength at that point.

If the centripetal acceleration of the planet is removed, still the planet would accelerate linearly falling towards the sun.

Hence, if the planets tangential velocity was reduced to zero, It would eventually crash into the Sun

Use the second laws of thermodynamics to explain how an incandescent bulb might be less efficient than a compact fluorescent bul
Vsevolod [243]

An incandescent bulb produces light that comes from the heating of a filament. A compact fluorescent bulb produces light when a substance is hit by electromagnetic radiation. Compact fluorescent bulbs are more efficient than incandescent bulbs.

The first law of thermodynamics is a version of the law of conservation of energy, adapted for thermodynamic processes. Therefore, a system with lower heat emissions would be more efficient.

The second law of thermodynamics states that the total entropy of an isolated system (the thermal energy per unit temperature that is unavailable for doing useful work) can never decrease. In our context, it means that the system with the least amount of losses would be more efficient. As a conclusion the fluorescent bulb would be more efficient.
