3 To improve the acoustics in auditorium, a sound reflector with mass
of 200 kg is suspended by a chain from the ceiling. What is its
weight? What force (magnitude and direction) does the chain exert
on it? What is the tension in the chain? Assume that the mass of the
chain itself is negligible.

Sagot :

To improve the acoustics in auditorium, a sound reflector with mass of 200 kg is suspended by a chain from the ceiling thus thet force (magnitude and direction) does the chain exert on it =1960 N.

What is Newton's third regulation?

Ths  0.33 regulation states that for each movement (pressure) in nature there's an identical and contrary response. If item A exerts a pressure on item B, item B additionally exerts an identical and contrary pressure on item A. In different words, forces end result from interactions.

  1. Weight of reflector = mg
  2. =200^ * 9.8
  3. =1960 N
  4. Force exerted with the aid of using chain =1960 N
  5. Direction = upwards
  6. Tension at the chain = weight of reflector
  7. =1960 N
  8. Weight of reflector =mg =100 * 9.8
  9. =980N
  10. Magniyof pressure reflector exerts on earth = 980 N
  11. (Due to movement response pair of forces, consistent with Newton's 0.33 regulation of motion.
