A 69 kg driver gets into an empty taptap to start the day's work. The springs compress 2×10−2 m . What is the effective spring c
natulia [17]

Answer:

3.4\cdot 10^4 N/m

Explanation:

The spring system in the taptap obey's Hooke's law, which states that:

F=kx

where

F is the magnitude of the force applied

k is the spring constant

x is the compression/stretching of the spring

In this problem:

- The force applied is the weight of the driver of mass m = 69 kg, so

F=mg=(69 kg)(9.8 m/s^2)=676.2 N

- The compression of the spring is

x=2\cdot 10^{-2} m=0.02 m

So, the spring constant is

k=\frac{F}{x}=\frac{676.2 N}{0.02 m}=3.4\cdot 10^4 N/m

In what factors sound can be heard​
MariettaO [177]

Explanation:

Loudness of sound is a measure of response of sound to our ear. Loudness of sound is not simply the energy reaching the human ear, but it also tells about the sensitivity of human ear detecting this energy. Loudness of sound is measured in decibel (dB). As energy reaching the ear depends on square of amplitude, loudness of sound depends on various factors namely,

(i) Amplitude of sound waves

(ii) Sensitivity of ear

(iii) Distance from the source of the sound and the listener.
