An object that weighs 3N displaces 280 mL of water which weighs 2.8 N. What is the buoyant force on the object?
Please help, idk how to find the buoyant force of an object thanks:D
Oh buoy, I'm here to make a splash and explain the buoyant force to you! The buoyant force is the upward force exerted on an object submerged in a fluid (in this case, water). It's equal to the weight of the fluid displaced by the object.
So, in this case, the object weighs 3N, whereas the water it displaces weighs 2.8N. To find the buoyant force on the object, you just need to subtract the weight of the water from the weight of the object.
Therefore, the buoyant force on the object would be 3N - 2.8N = 0.2N. Ta-da! That's the buoyant force in action.
To find the buoyant force on an object, you can use Archimedes' principle, which states that the buoyant force is equal to the weight of the fluid displaced by the object.
In this case, the object displaces 280 mL of water, which weighs 2.8 N. This means that the object displaces a volume of water that has the same weight as the object itself.
Since the object weighs 3 N, the buoyant force on the object is also 3 N.
To find the buoyant force on an object, you can use Archimedes' principle, which states that the buoyant force on an object submerged in a fluid is equal to the weight of the fluid displaced by the object.
In this case, we have an object that weighs 3N and displaces 280 mL (or 0.28 L) of water, which weighs 2.8N. To find the buoyant force on the object, we need to find the weight of the water displaced.
First, we need to convert the volume of water displaced from milliliters to liters. Since 1 L is equal to 1000 mL, we can divide 280 mL by 1000 to get the volume in liters: 0.280 L.
Next, we can find the weight of the water displaced by multiplying the volume by its density. The density of water is roughly 1 g/mL or 1000 kg/m³. Since the volume is 0.280 L, the weight of the water is calculated as follows:
Weight of water = density of water * volume of water
= 1000 kg/m³ * 0.280 L
= 280 kg
Now we have the weight of the water displaced by the object, which is 280 kg. However, we need to convert it to Newtons (N) to match the units of the object's weight. To convert kg to N, we can multiply by the acceleration due to gravity (approximately 9.8 m/s²).
Weight of water in N = weight of water in kg * acceleration due to gravity
= 280 kg * 9.8 m/s²
= 2744 N
Therefore, the buoyant force on the object is 2744 N.
