Why is a sinker necessary in determining the lifting effect of water?
Wiki User
∙ 9y ago
A sinker is necessary to determine the lifting effect of water because it helps to counteract the buoyant force exerted by the water on the object. By adding a sinker, you can measure the force required to keep the object submerged, which allows you to calculate the buoyant force acting on the object.

Why is there need to dry the sinker before using it?
Drying the sinker before using it helps to remove any moisture or contaminants that might affect the accuracy of the measuring scale. Moisture can add weight to the sinker, leading to incorrect measurements. Therefore, ensuring the sinker is dry helps to maintain the precision of the measurement process.
What mass of lead is required to make a 1 cm cubed fishing sinker?
AnswerThe density of Lead is 11.35kg per cubic metre this means that 100cm X 100cm x 100cm = 1 cubic metre so 1000000 cubic cm makes 1 cubic metre 1 cm cubed of lead = 11.35/1000000 =0.00001135 kg 0.01135 grams of lead in 1 cm cubedEDIT: The density of lead is 11,340kg per cubic metre - not 11.35kgs - Water has a density of 1,000 kgs per cubic metre, lead does not float on water, but it would if a cubic metre of it only had a mass of 11.35kgs!Otherwise the formula used for the calculation above is correct.1cm3 of lead has a mass of 11.340g
What does lead (the element) look like?
Pure lead looks is very shiny and looks like silver when it is first melted and cooled to room temperature. It will remain shiny for several days. As the exposed surface oxidizes, it will turn dull and grey. After years of oxidization, it will turn a white color, and will "look" like chalk but it will still be hard.
Are all volcanoes the same?
No, not all volcanoes are the same. Volcanoes can differ in terms of their size, shape, eruption style (explosive or effusive), composition of magma, and frequency of eruptions. These variations can lead to different volcanic hazards and impacts on surrounding areas.
What metric unit do people use to measure weight?
Weight is a force, and can be described in terms of any unit of force. The basic unit of force in the Metric system is the "Newton". If you were fishing for "kilogram", you used the wrong bait. Although it's true that 16 out of every 19 people will use the kilogram to describe weight, it's still wrong.
Why there is a need for a sinker in determining the specific gravity of objects lighter than water?
A sinker is needed to help submerge the lighter object in water to accurately measure the change in water level caused by its displacement. This helps determine the volume of the object, which is necessary to calculate its specific gravity. Without the sinker, the object may float and not displace enough water for an accurate measurement.
What important assumption have you made in determining the amount of heat released by the lead sinker?
One important assumption made is that the heat released is solely due to the lead sinker cooling down and not influenced by external factors such as nearby heat sources or changes in environmental conditions. Additionally, it is assumed that the transfer of heat is uniform throughout the sinker and follows standard thermodynamic principles.

How fast does a sinker fall through water?
The sinking speed of a sinker through water can vary based on factors such as its weight and shape. On average, a sinker can fall at a rate of about 2-5 feet per second in still water. However, this speed can change depending on the size and design of the sinker.
How do you throw a sinker?
It's really up to you. You don't want to pick one too big because it will drive the fish away. You want one that will just hold the line where you want it. If you are just fishing on a lake or still water then you would probably be fine with a 1 or 2 ounce sinker. Southernfishing101.webs.com
What happens to a dog who eats a fishing bobber a sinker and a hook?
Eating a fishing bobber, sinker, and hook can be very dangerous for a dog. These items can cause internal injuries, blockages, or even poisoning. Immediate veterinary attention is necessary to remove the objects and provide appropriate treatment to prevent any complications.
