The "ringing sound" are actually the soundwaves travelling from the phone to your ears.
Springs in series will experience the same force all throughout and the elongation will add up. Springs in parallel will experience different forces and the elongation will be the same for each. The ranking will be from lowest to highest:
Case 3
Case 2
Case 1
Case 4
Case 5
- Pressure = 2000 Pa
- Mass = 100 Kg
- We know, Force = mass × acceleration due to gravity
- Acceleration due to gravity = 9.8 m/s^2
- Therefore, the force = (100 × 9.8) N = 980 N
- We know, Pressure =
- Therefore, area of contact
