What is the pressure on a swimmer 10 m below, the surface of a lake ? |
|
Answer» SOLUTION :Here, `h = 10 m, G = 9.8 ms^(-2) , rho_w = 1000 KG m^(-3)` PRESSURE on a swimmer10 m below the surface of the lake. `P = P_(a) + h rho g = (1 xx 10^5) + (10 xx 9.8 xx 10^3)` `=10 xx 10^4 + 9.8 xx 10^4 = 19.8 xx 10^4` `P = 1.98 xx 10^5 ~~ 2 atm`. |
