The cabinet is being pulled with 200N and is being rested by a force equal to 200N. That is why it is not being moved. 


<span>Although the force of static friction can equal Fk=µs*F=m*g*µs=(30kg)*(9.8m/s^2)*(0.80)=235 N. It is not resisting the 200N force with 235N. Imagine if you pushed something with 200N and it pushed you back with 235N, especially a cabinet. You would think that the cabinet was alive.</span>

48 grams 12cm^3, what would the density of the material be
Licemer1 [7]
Density is mass over volume:

D =  \frac{m}{V}

In your case, mass is 48 grams and volume is 12cm^3

If you put that into the equation, you will get your density:

D =  \frac{m}{V} =  \frac{48g}{12cm^{3} } =4g/ cm^{3}
