Answer:
0.0257259766982 m
Explanation:
= Atmospheric pressure = 101325 Pa
= Initial diameter = 1.5 cm
= Final diameter
= Density of water = 1000 kg/m³
h = Depth = 40 m
The pressure is
![P_1=P_2+\rho gh\\\Rightarrow P_1=101325+1000\times 9.81\times 40\\\Rightarrow P_1=493725\ Pa](https://tex.z-dn.net/?f=P_1%3DP_2%2B%5Crho%20gh%5C%5C%5CRightarrow%20P_1%3D101325%2B1000%5Ctimes%209.81%5Ctimes%2040%5C%5C%5CRightarrow%20P_1%3D493725%5C%20Pa)
From ideal gas law we have
![\dfrac{P_1V_1}{T_1}=\dfrac{P_2V_2}{T_2}\\\Rightarrow \dfrac{P_1\dfrac{4}{3\times8}\pi d_1^3}{T_1}=\dfrac{P_2\dfrac{4}{3\times8}\pi d_2^3}{T_2}\\\Rightarrow \dfrac{P_1d_1^3}{T_1}=\dfrac{P_2d_2^3}{T_2}\\\Rightarrow d_2=(\dfrac{P_1d_1^3T_2}{P_2T_1})^{\dfrac{1}{3}}\\\Rightarrow d_2=(\dfrac{493725\times 0.015^3\times (20+273.15)}{101325\times (10+273.15)})^{\dfrac{1}{3}}\\\Rightarrow d_2=0.0257259766982\ m](https://tex.z-dn.net/?f=%5Cdfrac%7BP_1V_1%7D%7BT_1%7D%3D%5Cdfrac%7BP_2V_2%7D%7BT_2%7D%5C%5C%5CRightarrow%20%5Cdfrac%7BP_1%5Cdfrac%7B4%7D%7B3%5Ctimes8%7D%5Cpi%20d_1%5E3%7D%7BT_1%7D%3D%5Cdfrac%7BP_2%5Cdfrac%7B4%7D%7B3%5Ctimes8%7D%5Cpi%20d_2%5E3%7D%7BT_2%7D%5C%5C%5CRightarrow%20%5Cdfrac%7BP_1d_1%5E3%7D%7BT_1%7D%3D%5Cdfrac%7BP_2d_2%5E3%7D%7BT_2%7D%5C%5C%5CRightarrow%20d_2%3D%28%5Cdfrac%7BP_1d_1%5E3T_2%7D%7BP_2T_1%7D%29%5E%7B%5Cdfrac%7B1%7D%7B3%7D%7D%5C%5C%5CRightarrow%20d_2%3D%28%5Cdfrac%7B493725%5Ctimes%200.015%5E3%5Ctimes%20%2820%2B273.15%29%7D%7B101325%5Ctimes%20%2810%2B273.15%29%7D%29%5E%7B%5Cdfrac%7B1%7D%7B3%7D%7D%5C%5C%5CRightarrow%20d_2%3D0.0257259766982%5C%20m)

The central nervous system.
Answer:
Forces that the rider applies to the pedals, saddle and handlebars during speeding, hill climbing and starting are estimated from cine film records using elementary mechanics. The results are compared with force measurements obtained from an instrumented pedal. Pedal forces of up to three times bodyweight were recorded during starting. Handlebar loads were always significantly large.
