Which of these statements describes the relationship between mass and weight?
(1 Point)
Mass is always greater than weight.
Mass of an object changes based on location, weight stays constant.
Mass of an object is constant, weight changes based on location.
Mass and weight are the same measurement.
Answer:
Usually, the relationship between mass and weight on Earth is highly proportional; objects that are a hundred times more massive than a one-liter bottle of soda almost always weigh a hundred times more—approximately 1,000 newtons, which is the weight one would expect on Earth from an object with a mass slightly greater ...

How does the law of conservation of mass apply to chemical changes?
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.

A 1 kg object is located at a distance of 1.0 x 103 m from the center of a larger
object whose mass is 2.0 x 1020 kg.
a. What is the size of the force acting on the smaller object?
The force = 1.334 x 10⁴ N
Further explanationGravity 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:

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

A 35 kg child has 190 J of kinetic energy after sledding down a hill. What is the child's speed in meters per second at the bottom of the hill?
Given: Mass= 35kg
Ekinetic= 190 J
Analysis: Ek= mv^2/2
solution: 190J=35v^2/2
V=square root(2×190)÷2= 3.2 m/s
The child's speed in meters per second at the bottom of the hill is 3.235 meter/sec.
What is Kinetic Energy?It is the type of energy an object has due to its motion. it is directly proportional to the product of mass and the square of the velocity of the object. It is given by the formula,
Kinetic Energy = 0.5 × Mass × (Velocity)²
Given that the mass of the child is 35 kg and the kinetic energy of the child after sledding down a hill is 190 J. Therefore, the speed of the child can be written as,
Kinetic Energy = 0.5 × Mass × (Velocity)²
190 J = 0.5 × 35 kg × (Velocity)²
(Velocity)² = 190 J / (0.5 × 35 kg)
(Velocity)² = 10.857142
Velocity = √10.857
Velocity = 3.235 m/sec
Hence, the speed is 3.235 m/sec.

HELP! A class is performing an experiment to keep an ice cube solid for as long as possible. which students actions could be a source of error in this experiment?
A. Jody included a fan in her experiment, and Katie did not use a fan.
B. Maria wrapped the ice cube tightly in cotton and aluminum foil.
C. Jerrie used different sized ice cubes each time he repeated the experiment.
D. Carey measured the quickly melting cube every 5 minutes.
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.

If plants do not get watered, they will start to wilt because their central vacuoles are empty. When they get water again, they will stand back up because their vacuoles have filled back up. What process allows their vacuoles to fill back up with water? *
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.

why does nobody love me?
Answer: I’m sure theirs people out there that like you, and if there isn’t, you should just focus on yourself.
Explanation:
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 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.

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

What is the relative humidity if the dry-bulb temperature is 18°C and the wet-bulb temperature is 11°C?
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.

A tennis racket strikes a tennis ball with a force of 100 N. With what force
does the ball strike the racket? *
Answer:
-100N
Explanation:
Newton's third law of motion states that to every force exerted on one body, there is an equal and opposite force. This means that if object A exerts an ACTION force on B, there is a force called REACTION FORCE, which is equal and opposite, exerted on A by B.
The action and reaction forces are equal in size/magnitude but opposite in direction. In this case where a tennis racket strikes a tennis ball with a force (action force) of 100N, the ball will strike the racket with a reaction force of -100N.
