What is the force of gravity acting on the block (the weight) in water?
The force of gravity on a block is the same, whether it is in air or in the water. The apparent weight (the force you need to keep it from falling) is less in water, due to the buoyancy force, which counteracts the weight.
A block of styrofoam floats on water while a same size block of lead lies submerged in the water The buoyant force is greatest on the?
The block of Styrofoam floats on water while a same size block of lead lies submerged in the water. The buoyant force is greatest on the lead. Compared to an empty ship, the same ship loaded with Styrofoam will float lower in the water.
Does the ship sink or rise in salt water?
The ship has two forces that affect the fraction of its volume that is above the surface of the water. The ship's weight is the downward force. The buoyant force is the upward force. Since the ship is floating, the magnitudes of these two forces are equal. The buoyant force is dependent on the density of the water. The density of salt water is greater than the density of fresh water. Let's look at the equation below. Buoyant force = Density * g * Volume of displaced water According to the equation, the buoyant force is directly proportional to the density. Since salt water is denser than fresh water, the buoyant force will be greater in salt water than fresh water. This force will push the ship up higher than if the ship was floating in fresh water. You could do this at home. Make a saturated solution of salt water. Then place a small wooden block into a glass of salt water. Use a ruler to measure the height of the fraction of the block that is above the surface of the salt water. Then place the block into a glass of fresh water and measure the height of the fraction of the block that is above the surface of the fresh water. You will see that the block is floating higher is salt water than in fresh water.
Why a piece of wood left under water come to the surface?
Due to buoyant force
Two solid blocks of identical size are submerged in water One block is lead and the other is aluminum Upon which is the buoyant force greater?
I would say the the lead displaces less water. Think about the sizes and densities. If you have a block of lead and a block of aluminum (weighing the same), common sense tells you, the lead block is going to be a lot smaller due to his great density. Therefore, smaller block displaces less water
A block of plastic is released under water will it sink or come up to the surface of water?
The density of water is greater than that of plastic. When a block of plastic is under water, the magnitude of the buoyant force or upthrust exerted by water on the block is greater than the magnitude of the weight of the block. Hence, the block of plastic released under water will come up to the surface of water.

A wooden block is in such perfect contact with the bottom of a water tank that there is no water beneath it. Is there a buoyant force on the block?
No. In fact, it's a question of density not of buoyancy. As it is less dense than the water, the water will sink below the block.
What force is needed to keep a wooden block of density 720 kg and volume 1.0 m3 under water?
Using the rough rule-of-thumb: 1 liter of water = 1 kg.-- The block sinks until it has displaced 720 liters of water. At that point,the mass of the displaced water has the same weight as the mass of theblock has, and the block sinks no further.-- The block still has 280 liters of its volume above water. If that were submerged,another 280 kg of water would be displaced.-- The additional 280 kg of water would weigh (280 x 9.8) = 2,744 newtons (617.3 pounds).That much additional buoyant force would fight the effort to submerge the block.It takes an additional 2,744 newtons (617.3 pounds) to keep the block under water.
A block of wood of mass 3.5 kg floats in waterCalculate the buoyant force on the block?
mass of the block is 3.5kg so block is floats on the water then we are say density of the body less than the water there is only along normal force acting the body buoyant force=mass*gravity B=3.5*9.8 B=34.8Kg/m/sec^2. thank you

A steel block has a volume of 0.08m3 and a density of 7840kgm3 what is the force of gravity acting on the block in water?
Density = 7,840 kg/m3 Volume = 0.008 m3 (= 8 liters). Mass = (7,840 x 0.008) = 62.72 kg Force of gravity on the block = (9.8 x 62.72) = 614.656 newtons (138.27 pounds) Bouyant force = weight of 8 liters of water = 78.4 newtons (17.64 pounds) Weight of the block in water = (614.656 - 78.4) = 536.256 newtons (120.64 pounds)
A steel block has a volume of 0.08 m and a density of 7840 kgm What is the force of gravity acting on the block the weight in water?
5362.56 NEWTONS
What Force pulls thing under water?
It's because of Density.
Where is the engine no stamped on a 390 F E big block ford?
On my '65 Galaxie500XL, it was on the front, right face of the block. Located just under the head, and to the right of the water pump. On my '65 Galaxie500XL, it was on the front, right face of the block. Located just under the head, and to the right of the water pump.
Can water block gps?
Water is a great blocker of GPS signals. That is why it is hard to get a GPS position under leaf trees: they have water in their leaves.
