Sample Response: The root beer exerts a force on all
sides of the ice cream. These forces are all equal and
cancel each other out. Gravity pushes downward on the
ice cream. This can also be called the weight of the ice
cream. Buoyant force pushes the ice cream upward. The
ice cream floats because the buoyant force is greater than
the weight of the ice cream.

PLEASE HELP ME!!!!!!!! Explain why understanding the process of combustion requires using an atomic model of mass and not a continuous one.
Answer:
Three things are required in proper combination before ignition and combustion can take place---Heat, Oxygen and Fuel.
There must be Fuel to burn.
There must be Air to supply oxygen.
There must be Heat (ignition temperature) to start and continue the combustion process.

Answer:
rubbing alcohol and bleach creates chloroform which is quite dangerous. Chloroform damages the liver, causing hepatitis, and it can also harm the kidneys, brain, heart, and bone marrow. Respiratory injuries can also come from chloroform exposure, they include respiratory depression, pneumonitis, and pulmonary edema.
why unit of force is derived unit?
Answer:
Because it is the product of two more basic units, mass and acceleration. The calculation of force is as follows:
Force=mass*acceleration
Mass is a base unit, acceleration is a derived unit calculated as a function of length and time which are both base units.
Any unit definition that is a function of more basic units is considered a derived unit.

Which force is equal but opposite to the one shown ?
Answer:b
Explanation:
i just know
The arrow in the photo represents a force. The ground applying a force on is equal but opposite to the one shown. Therefore, option B is correct.
What is force ?A force is an influence that has the power to alter an object's motion. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Force is used to describe a body's tendency to modify or change its state as a result of an external cause. When force is applied, the body can also alter its size, shape, and direction.
In terms of a physical action or movement, force is essentially a push or pull that acts on an item or energy. When two things come into contact, it occurs. Additionally, a body is in motion when it is moving.
Thus, option B is correct.

Which could describe the motion of an object? distance = 1 meter and displacement = 10 meters distance = 10 meters and displacement = 100 meters distance = 0 and displacement = 10 meters distance = 10 meters and displacement = 10 meters
Answer:
Distance = 10 meters and displacement = 10 meters
D.
The right statements which could describe the motion of an object are:
distance = 10 meters and displacement = 1 meterdistance = 10 meters and displacement = 0distance = 10 meters and displacement = 10 meters Distance is known to be a scalar quantity. it shows the rate or ground an object has covered when in motion. Displacement is known also to be a vector quantity. It shows the rate o how far out of place an object is been. it is known as the object's overall change in position.Distance is measured in interval between two locations measured along the actual path connecting them.
Displacement is measured the interval between two locations measured along the shortest path connecting them.
Conclusively, the motion of an object is done by the position, speed, direction, and acceleration.

emergency (30 points) what conclusion can you make about the relationship between temperature and pressure?
Answer:
This relationship between pressure and volume is known as Boyle's lawA law that states that at constant temperature, the volume of a fixed amount of a gas is inversely proportional to its pressure., after its discoverer, and can be stated as follows: At constant temperature, the volume of a fixed amount of a gas is. The pressure law states that for a constant volume of gas in a sealed container the temperature of the gas is directly proportional to its pressure. This can be easily understood by visualising the particles of gas in the container moving with a greater energy when the temperature is increased.
Explanation:
Answer:
basically increased temperature causes an increase in pressure. and vise versa.

A cup of gold colored metal beads was measured to have a mass 425 grams. By water displacement, the volume of the beads was calculated to be 48.0 cm3. Given the following densities, identify the metal.
Gold: 19.3 g/mL
Copper: 8.86 g/mL
Bronze: 9.87 g/mL
Given parameters;
Mass of gold colored metal beads = 425g
Volume of water displaced by beads = 48.0cm³
Unknown;
Identity of the metal = ?
Given densities;
Gold: 19.3 g/mL
Copper: 8.86 g/mL
Bronze: 9.87 g/mL
Density is an intensive property of any substance. This implies that we can use the density of any substance to identify it.
Density can be defined as the mass per unit volume of a substance. Every substance has a unique mass per volume.
Mathematically;
Density = [tex]\frac{mass}{volume}[/tex]
where mass is in kg or g
volume is in m³ or cm³
To find the density, we must know the mass and volume.
In this problem, the volume of the gold metal beads is the same as the volume of water displaced. This is a way to measure volume of solids.
Since the volume is given in cm³, and we are comparing with choices that have units in g/mL, we simply convert the volume in cm³ to mL
1cm³ = 1mL³
So therefore, volume of gold colored metal is 48mL
Now input the parameters given and solve for the density;
Density = [tex]\frac{425g}{48mL }[/tex] = 8.85g/mL
From the given densities, we clearly see that copper is the metal since they both of similar densities.
