Intro Tab:
1. How can you use a block and the other tools on the Intro tab to determine the density of the "Oil"?
2. Determine what forces act on an object when is it in a fluid. How are the forces similar and different when the object sinks, floats immersed in the fluid, and when it is only partially submerged.
3. Give specific examples that you could use to explain what buoyancy is and how an objects weight can appear to change when in a fluid. Make sure to include situations where the object sinks, floats immersed in the fluid, and when it is only partially submerged.
Playground Tab:
4. Explain how you can use the information about the block and the fluid to determine if the block will sinks, floats immersed in the fluid, and when it is only partially submerged.
5. How can you determine the apparent mass of an object if you know the density of the object and the density of the fluid?
6. Challenge: Explain how an object that is more dense than water can be kept afloat by placing it on an object that is less dense than water.
Suppose you hold a f=5.0 cm magnifying glass 3.0 cm from a 2.0 mm high ant. how large is the image of the ant
The uniform rectangular plate of mass m is suspended by three cables. Determine the tension in each cable.
A 2.00 kilogram package is released on a 53.1 degree incline, L =4.14 meter from a long spring with force constant 120 N/m that is attached at the bottom of the incline. Find the speed of the package just before it reaches the spring
A rocket with an initial mass of 1000kg adjusts its thrust by varying the rate at which mass is ejected. The ejection speed relative to the rocket is 40 km/s. If the acceleration of the rocket is to have a magnitude of 20 m/s2 at an instant when its ..
Hoover Dam produces electricity for residents of Nevada, Arizona, and California. The dam is 200 meters tall. Lake Mead sits at the top of the dam and contains about 10 billion cubic meters of water. Estimate how much gravitational potential energy i..
