1.)
So I would have to convert the meters to cm?
buoyant force= 1g/cm cubed x 100 cm cubed x 980 cm/s squared
buoyant force = 980 gcm/s squared
So, the weight equals 980 g?
Yes, it is. It's given me that the volume is 1 meter cubed. But I thought I had to know how much of the water that's displaced to find out the buoyant force. If the buoyant for is the amount of the object immersed, then it would be 1/3 meter cubed. But then all I know is that the weight is equal...
1.) 1 m3 object is floating in water. A third of the object is submerged. How much does the object weigh?
2.) Consider a floating hollow plastic box that has negligible mass. The volume of the box is 0.002 m3. If a 3.5 kg piece of copper is placed in the box, will the box sink or...
Homework Statement
Describe what happens to an object traveling close to the speed of light from
the point of view of a stationary observer.
(Hint--there are three differences).
The Attempt at a Solution
I just don't understand what it means by there being three differences?
