The correct Answer is:
To solve the question regarding the sound level generated by the takeoff of a jet plane, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Question:** The question asks for the sound level in decibels (dB) generated by the takeoff of a jet plane. 2. **Identifying the Options:** The options provided are 80 dB, 50 dB, 100 dB, and 150 dB. 3. **Knowledge of Sound Levels:** We need to recall the typical sound levels associated with various sources. - Normal conversation is around 60 dB. - A lawnmower is about 90 dB. - A jet plane during takeoff is known to produce very high sound levels. 4. **Researching Jet Plane Sound Levels:** It is widely known that the sound level produced by a jet plane during takeoff can reach very high levels, often cited around 150 dB or more. 5. **Selecting the Correct Answer:** Based on the information gathered, the sound level generated by the takeoff of a jet plane is approximately 150 dB. 6. **Final Answer:** Therefore, the sound of **150 dB** is generated by the takeoff of a jet plane.

Assertion : A brief expoosure to extremely high sound level, 150dB or more generated by take off of a jet plane or rocket, may damage ear drum or dislocate ear ossicles and permanently impair the hearing ability. Reason : In India, the Air (Prevention and Control of Pollution ) Act came into force in 1981, but was amended in 1987 to include noise as an air pollutant.

150 dB or more sound is generated by

Pollutant of jet planes is:

The level of sound is attenuated by 30 dB by a sound absorber. The intensity of sound will decrease by a factor of

The pollutants released by jet planes are :

A supersonic jet plane moves parallel to the ground at speed v= 0.75 mach (1 mach = speed of sound). The frequency of its engine sound is v_0= 2kHz and the height of the jat plane is h= 1.5 km. At some instant an observer on the ground hears a sound of frequency v= 2v_0 . Find the instant prior to the instant of hearing when the sound wave received by the observer was emitted by the jet plane. Velocity of sound wave in the condition of observer =340 m"/"s .

Waves produced by supersonic jet planes are
