Hi I need help with this Multiple Choice question:
A 10 cm^3 piece of wood if forced to be fully submerged 2.0 m below the surface of the lake. Which statement below is true?
Density of wood is larger than the density of water.
A) Buoyant force acting on the wood is less than the weight of the piece of wood.
B) The buoyant force acting on wood piece would be larger if this object was submerged 3.0 m below the surface of the lake.
C) To know whether buoyant force is larger than the weight, one needs to know the specific value of atmospheric pressure.
D) All of these statements are false.
When water fills a narrow glass tube, the top surface of the water turns out not to be flat. First, (i) describe what the surface of water in a glass tube looks like (you may draw a picture instead of or in addition to your written answer). Next, (ii) state the term used to describe this phenomenon. Then, briefly (iii) explain why the surface of the water changes in this way. Finally, (iv) explain how the volume of water in such a tube is properly determined given what happens to the water’s surface.
Please answer parts B, C and D!
A beachball has a diameter of 24 cm and weighs about 6N.
A-What is the volume of the beachball? Then, use this number to calculate the beachball’s average density in kg m-3.
B-What is the volume of water displaced by the beachball if it is in the pool?
C- Now, using a rope, you tie the beachball to the bottom of the pool so only half of the ball is submerged. What would the diagram look like?
D- What is the buoyant force of the tethered beachball? What is the tension on the rope?
