Answer: the intensity of sound at a rock concert will be 6.31 × 10^12 time louder than that of a whisper.
Explanation: Given that sound at a rock concert power is 130 dB of intensity l2
a whisper power is 2 dB of intensity l1
Using the formula
130dB - 2dB = 10Log(I2/I1)
128/10 = logI2/I1
12.8 = log (I2/I1)
I2/I1 = 6.31 × 10^12
Therefore, the intensity of sound at a rock concert will be 6.31 × 10^12 time louder than that of a whisper.
Answer: Gravity will be on you since you are falling. For instance if you where skydiving you are free falling which will be similar to the car. Therefore gravity does play a role because whatever goes up must come down.
Explanation:
The mechanical advantage of a machine is the ratio of the force produced by the machine to the force applied to it. Therefore, we may calculate the applied force using:
Mechanical advantage = force by machine / force applied
6 = 2 / force applied
Force applied = 1/3
Thus, the distance that the effort must move will be 1/3 inch
