Thank you! It makes sense now

okay, thank you! :)

An object is completely under water, hovering, neither rising nor sinking. Its mass is 100 kg. What is the buoyant force on the object, in Newtons? (a) 12,460 (b) 17,860 (c) 16,080 (d) 9800 (e) none of these Since buoyant force is equal to the weight of the object, I figured I could...

I'm still a little confused.. So would I plug it into m=pv? 12=1000 x V

Thank you! :)

A 12 kg wooden block is floating in a swimming pool. The density of the wood is 600 kg/m3. How many cubic meters of water does the block displace? (a) 0.044 (b) 0.066 (c) 0.012 (d) not enough information to answer (e) none of these I'm really confused on this concept. I know that the...

A 1.2 kg block is pushed beneath the water and held there. What is the buoyant force (in N) acting on the block? (a) not enough information to answer (b) 11.76 (c) 1.2 (d) 14.56 (e) none of these Since buoyant force is equal to the wt of the water displaced, I used the equation w=mg...

Oohhh, so I would calculate the buoyant force and then subtract that from the weight of the boulder, so I get the force that the boulder exerts on the ground? If I multiply volume x density of water x force of gravity: 0.4 x 1000 x 9.8 = 3920 and then subtract this from 20,000 I get 16080...

I know the weight of the boulder is 20,000 N and the volume is 0.4 m^3 Wouldn't the answer just be 20,000? Since the force is the same thing as weight? the options are: (a) 12,460 (b) 17,860 (c) 16,080 (d) 14,450 (e) none of these

difference between the amount of water displaced by a floating vs submerged object?? I'm so confused. Let's say you have the mass and density of a floating object. How would you find the volume of the water displaced? And how is this different from finding the volume of water displaced by...
