A. 10 million N
B. 9.8 million N
C. 98 million N
D. 980 million N
Wrong Points Earned: 0/1
Correct Answer: A
Your D
Homework Equations
p=f/a
density=rho
rho=mass/volume
rho(water)=1000kg/m^3 or 1g/cm^3
The Attempt at a Solution
to float the buoyant force must equal the weight of the boat?
so rho*V*g=m*g
rho=m/v
1000=10million/v
v=1000/10million
1000kg/m^3*(1000/10million)*9.8)=10million*9.8
??wait, where am i solving for?? there is no open variable that needs solving egh...
