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 happens to light when it hits a surface?
When light hits a surface, three things can happen: it can be absorbed by the surface, reflected off the surface, or transmitted through the surface. The amount of light that is absorbed, reflected, or transmitted depends on the properties of the surface material.
What are two forces that affect nearly all motion?
Two forces that affect nearly all motion are gravity, which pulls objects towards the Earth's center, and friction, which opposes the motion of objects moving against a surface.
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.
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').
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.
What is the nearly level land on Earth's surface called?

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.
Are electrons nearly weightless particles?
Electrons have a very small mass, approximately 9.11 x 10^-31 kilograms. While their mass is small compared to larger particles, electrons do have a measurable weight due to their mass.
What is the surface temperature of the sun is nearly?
The surface temperature of the sun is around 5,500 degrees Celsius (9,932 degrees Fahrenheit).
What covers nearly 98 percent of Antarctica?
Fresh-water ice covers nearly 98 percent of the Antarctic continent, equal to 10 percent of the earth's surface.
What is the name given to a large area of level or nearly level land on earth surface?
