Block B in rests on a surface for which the static and kinetic coefficients of friction are 0.59 and 0.40, respectively. The ropes are massless. What is the maximum mass of block A for which the system remains in static equilibrium?

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

the answer is to check all of them! they all apply well at least i think so!

the answer is b, have negligible mass

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.
