Answer:

osmosis

Explanation:

The process that allows the vacuoles of plants to fill back up with water after a period of wilting is osmosis.

Osmosis is the movement of water molecules from a region of higher water potential to a region of lower water potential through a semi-permeable membrane. Water enters the vacuoles of plants osmotically once water becomes available in their cells.

The availability of water in the cytosol makes it to have a higher water potential than the cell sap. In this case, the vacuole membrane or the tonoplast acts as the semi-permeable membrane and allows water to diffuse into the vacuole.

Answer:

B. Maria wrapped the ice cube tightly in cotton and aluminum foil.

Explanation:

According to this question, a class is performing an experiment to keep an ice cube solid for as long as possible. However, in the experimental procedure that will be used to actualize this aim, certain protocols must be duly observed to avoid error in the experiment.

Among the listed options containing actions taken by students, wrapping the ice cube tightly in cotton and aluminum foil is a likely source of error to the experiment. This is because aluminum, owing to its metallic properties, is a good conductor of heat. Hence, Aluminum foil will conduct heat and cause the ice cube to melt faster than normal.

This will jeopardize the aim of the experiment, which is to keep an ice cube solid for as long as possible.

Answer:

The ability to do work or cause change is called energy. Energy comes from many sources, and is found in two main forms. One form, potential energy, is energy that has the potential, in an object at rest, to do work later. An example of this would be a car parked at the top of a hill with its brakes on.

Explanation:

i'm built different

Energy is defined as the ability to do work or cause change . It is common

and present in all forms of living and non-living organisms.

The primary source of energy is regarded as the solar(light) energy which

helps in the production of chemical energy by plants in the form of

food(starch)

Subsequent inter-conversion of forms of energy occurs such as conversion

of  chemical energy to electrical , kinetic energy etc.

Answer:

Q = I * t = 2 Coulomb / sec * 1000 sec = 2000 Coulombs transferred

E (energy) = V * Q = I * t * 240 V

E = 240 J / Coul * 2000 Coul = 480,000 Joules

Answer:

the mass of each object and the mass of each object and the distance between them

Explanation:

Answer:

The Law of Conservation of Mass states that matter cannot be created nor destroyed. It can only be transformed from one state or substance to another. This means that this law applies to both physical and chemical changes. In physical changes, the substance before and after the phase change still has the same mass.

Explanation: Hope it helps

Answer:

A

Explanation:

I think its a because A would be heavier making it go down faster than B. its like when you drop a father compared to a ball, the feather is lighter so it will go down slower than the ball because it has more mass

Answer:

Well, There are a couple reasons it could seem like nobody loves you...

Explanation:

One reason is that people really do love you, they just were never shown love and affection so they are unsure of how to show that to you. Another reason could be that it's god telling you that you are meant for much bigger and greater things. Maybe it's him reminding you that, yeah, people really suck, but that's life, and you're better than that. If you make the right decisions in life, you will be able to stand taller than they ever did. I hope this helps.. : )

Answer:

The amount of moisture air can hold is dependent on its temperature and pressure. The warmer the air the greater the quantity of water vapour it can contain. The air temperature is measured with a normal thermometer this is the Dry-Bulb reading. The actual amount of moisture known as the mixing ratio is measured in grams of water per kilogram of dry air. When air at a certain temperature is saturated it cannot hold any more moisture. The relative humidity of the air is the ratio of the actual amount of moisture in the air to the fully saturated amount.

We can use evaporation to measure the amount of moisture in the air. A wet cloth is placed over the bulb of a thermometer and then air is blown over the cloth causing the water to evaporate. Since evaporation takes up heat, the thermometer will cool to a lower temperature than a thermometer with a dry bulb at the same time and place. The depression in Wet-Bulb temperature allows the humidity to be calculated. If the air is fully saturated (100% relative humidity) the water cannot evaporate, so both the wet and dry bulb temperatures are the same. If the dry and wet bulb temperatures are set to the same value the calculator will show the saturation mixing ratio the amount of water in saturated air at that temperature.

If partly saturated air is cooled without changing its pressure or amount of water vapour, a point is reached when it becomes saturated. The moisture will be given up as dew or ice crystals. This temperature is the Dew Point. This is why condensation will form on a bottle of cold beer, as the air in the vicinity of the bottle is cooled below its dew point. Meteorological reports usually quote the temperature and dew point as well as the station pressure. Moisture content and relative humidity can be calculated from these figures.

The Psychrometer is the name of a device containing both a wet and dry bulb thermometer. This can be a fixed device for meteorology or a handheld sling psychrometer that is often used in air conditioning applications.

Explanation:

The force = 1.334 x 10⁴ N

Gravity is a force that arises because of the attraction between objects with mass.  

The magnitude of this attraction is proportional to the mass of the object.  

The greater the mass of the object, the greater the gravitational force  

Relationships can both be stated in  

Newton's Gravity Law:  

[tex]\rm F=G.\dfrac{m_1.m_2}{r^2}[/tex]

with F = gravitational force,  N

G = gravitational constant,  6.67 x 10⁻¹¹ Nm²/kg²

m1, m2 = mass of object,  kg

r = distance between two objects.  m

m₁= 1 kg

m₂=2 x 10²⁰ kg

r = 1 x 10³ m

The force acting on the smaller object=The force acting on the larger object(Newton's Third Law)

[tex]\tt F=6.67\times 10^{-11}\dfrac{1\times 2.10^{20}}{(1\times 10^3)^2}\\\\F=1.334\times 10^4~N[/tex]
