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.
- Weight of reflector = mg
- =200^ * 9.8
- =1960 N
- Force exerted with the aid of using chain =1960 N
- Direction = upwards
- Tension at the chain = weight of reflector
- =1960 N
- Weight of reflector =mg =100 * 9.8
- =980N
- Magniyof pressure reflector exerts on earth = 980 N
- (Due to movement response pair of forces, consistent with Newton's 0.33 regulation of motion.
