How much force is needed to push a nearly weightless but rigid 1-l carton beneath a surface of water?

In order to submerge the 1-liter carton, you must displace 1-liter of water.
The carton will be buoyed up by the weight of that 1-liter of water.
The mass of 1-liter of water is nominally 1 kilogram.
On earth, 1 kilogram of mass weighs 2.205 pounds. (rounded)
That's the force needed to keep the carton submerged.

What does the inner core have?
inner core of earth? it contains melted rocks, metals and minerals since the core has nearly the surface temperature of sun
What happens to light when it hits a surface?
Three things can happen 1. Absorb the light, like black clothing 2. Bounce off the surface, like a mirror 3. Nearly all the light can go through, like a window
Do liquids that have higher tension produce drops that are flatter or more nearly sperical ttan liquids with lowersurface tension?
Surface tension causes molecules to hold to themselves more tightly. Therefore high surface tension liquids, like pure water, will form a taller drop and low surface tension substances, like oil, will spread out and be flat.
When will an object float on a fluid's surface?
To be straight in answering,I would write that if that particular object has its density nearly equal to the density of fluid displaced by its submerged part then only the object will be likely to float in the fluid.
Why do beads of water often from on a slippery surface such as a freshly waxed car?
Short answer:Water beads form on a surface when the cohesion of the water molecules with each other is much greater than the adhesion of the water to the surface. Water cohesion results in water having high surface tension and hence a strong tendency to form spherical droplets. Water adhesion to waxy or oily materials is small. The result is a tendency to form water beads.This phenomena, or the lack there of, is called wetting and has been studied for centuries. The cohesion of a liquid is directly related to the surface tension of a liquid. Water, which has a high surface tension, readily forms beads on materials which are hydrophobic, i.e. materials with a small adhesion to water. The waxed surface of a car has small adhesion and so water beads form regularly. The raw painted surface of the car would have more adhesion with water and so greater wettability. The opposite extreme, the tendency of a liquid to wet a surface due to strong adhesion, is critical to a situation such as lubrication where the liquid should coat the solid surface. It is the two properties combined, adhesion and cohesion, which determine wettabilty and beading.Long Answer:When one speaks of water beading on a surface, one means the formation of small droplets of water on a surface. This phenomena depends not only on the properties of water and the surface, but most importantly on the property of the interaction of the water with the surface. In science, this is the topic of "wetting" and one describes the tendency in terms of the "wettability" of a particular combination of liquid and surface. Beading is a manifestation of low wettability or little wetting.A liquid droplet on a surface tends to form a more nearly spherical shape if the forces of attraction (or cohesion) between the liquid molecules is strong and the forces between the liquid and and the solid (adhesion) are weak. We associate strong cohesive forces of a liquid with a high surface tension and a high surface tension opposes wetting. Water is an example of a liquid with high surface tension.The interaction of water with a surface like wax or plastic or Teflon is an example weak adhesion or weak forces between the liquid molecules and solid surface. Thus, wetting is highly unfavorable and formation of nearly spherical droplets is favored and we say water beads. Surfaces like metal or glass have somewhat stronger adhesive forces so wetting is greater and droplets are less spherical.
Are electrons nearly weightless particles?
yes.
Where on earth is the mantle?
The mantle isn't on the Earth, it is in the Earth. On land the uppermost part of the mantle is 15 to 45 miles beneath the surface. It extends down to the core-mantle boundary at a depth of nearly 1800 miles.
What is meaning of the prefix sub?
The latin Prefix 'Sub' can mean 'under', 'beneath', or 'below' (such as in the Word 'Subconscious'), 'inferior to', or 'part of' (such as in the Word 'Subhuman'), 'less than normal' (such as in 'Substitute'), or 'almost/nearly' (such as in the Word 'Subcentral').
What is the surface temperature of the sun is nearly?
6000 k
Is there more land or water on earth?
There is more water on Earth than land (surface area). Water covers nearly 71% of the Earth's surface. While Earth's surface is mostly water, Earth is nearly all rock. Just 0.5% of the planet by weight is water. -Thong Tran
The global ocean blankets nearly percent of Earth's surface.?
Ocean water makes up about 71% of the Earth’s surface.
Where is the ivory claw in skyrim?

What is the nearly level land on Earth's surface called?
Plains.
Which axial skeletal bone has a small flat articular surface?
Facet has a small, nearly flat articular surface
Does a basketball have a lot of surface to volume ratio?
No. A sphere has the smallest surface to volume ratio possible and a basketball is nearly spherical in shape (it has surface dimpling and seams).
What increases the surface area of this part of the brain?
The folds in the brain increase the surface area. It nearly triples the surface area. As we grow, more of these bends form.
When maritime tropical air mass is cooled by a colder ground surface the weather often is what?
Stays nearly the same but the surface temperature
