You could put a 1 kg weight inside the barrel to make it weigh 8 kg.
You can put a hole in the barrel to make it weigh 8 kilograms.
An empty barrel that weighs 9 kilograms can be reduced to 8 kilograms by putting a hole in it. The hole has to be large enough to remove exactly 1 kilogram from the barrel.
To make the barrel of water weigh 12 pounds, you would need to remove 8 pounds of water from the barrel.
A 1000 gallon plastic container typically weighs around 200-250 pounds when empty. The weight can vary depending on the specific design and thickness of the plastic used to make the container.
You have to add AIR.
You can put a hole in the barrel to make it weigh 8 kilograms.
Wait a couple of hundred years and put anti-gravity in it. Put air in it and take it on a ride on the vomit comet aircraft to have the barrel experence weightlessness. Maybe you could just take the top off and let it fill with the sorrounding air and it will weigh less while the top is off. BEST ANSWER: A HOLE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!11
The correct wording is "Empty vessels make the most noise". When you knock on a empty barrel, it's loud, a full barrel is quiet. SO, he who has nothing to say - says too much.
An empty barrel that weighs 9 kilograms can be reduced to 8 kilograms by putting a hole in it. The hole has to be large enough to remove exactly 1 kilogram from the barrel.
a big hole
Helium has a lower density than air, therefore replacing the air in the barrel with helium decreases the mass of the barrel system thus the weight is decreased.
To make the barrel of water weigh 12 pounds, you would need to remove 8 pounds of water from the barrel.
Use a density factor to make a barrel to ton conversion. The ton is a metric weight and the barrel is a volume measurement.
The weight of empty bottles can vary based on their size and material. For example, a standard empty plastic bottle (like a 500ml bottle) typically weighs around 10-15 grams. Therefore, it would take approximately 67,000 to 100,000 empty plastic bottles to make a ton. For glass bottles, which weigh more (around 300 grams for a standard bottle), it would take about 3,333 empty glass bottles to make a ton.
by first weighing the tank when empty, then a 20 lb tank will weigh 20lb plus the empty weight when full. . so if the tank weighs 15 lb empty and now weighs 25 lb , then it is half full , or half empty !!!!!!!!!!!!
To solve this problem, we need to understand the concept of buoyancy. When the bucket is half-filled with water, the water exerts an upward buoyant force equal to the weight of the water displaced. Since the weight of the half-filled bucket is 30kg, the weight of the water in the bucket is 30kg. This means the weight of the empty bucket is 20kg (50kg - 30kg = 20kg).
I would add -5
