Answer:
Increase the amount of gas
Explanation:
By increasing the pressure of the solution, the amount of gas will have to increase. Solubility of gases increases as the pressure is made to increase. Before the pressure was increased, the gases moved freely about. But as it was increased, theses gases had more frequent collisions within this solution. Causing an increase. The liquid on its own will experience no changes.

An air conditioner with a resistance of 50.0 Omega(R1) and a computer with a resistance of 20.0(R) are connected in parallel to a 120.0-V source through a 2.00-0 resistor (R3) series, as shown below. Find the current through the computer when the air conditioner is on and when is off
Answer:
the value of current will be 6A for the both case.
Explanation:
the voltage difference between two sides of the computer will be 120V .it will not depend on while the conditioner is on or off. so for the both case it will be same.
as we know current I=V/R
so for the both case I=120/20=6(ans)
A baby carriage is sitting at the top of a hill that is 35 m high. The
carriage with the baby has a mass of 1.5 Kg. What is the potential
energy?
Answer:
[tex]\boxed {\boxed {\sf E_p= 515.025 \ J}}[/tex]
Explanation:
Potential energy is found using this formula:
[tex]E_p= mgh[/tex]
The mass of the baby in the carriage is 1.5 kilograms and the height is 35 meters. Assuming this is on Earth, the gravitational acceleration is 9.81 meters per square second.
[tex]m=1.5 \ kg \\g= 9.81 \ m/s^2\\h= 35 \ m[/tex]
Substitute the values into the formula.
[tex]E_p= (1.5 \ kg )( 9.81 \ m/s^2)(35 \ m )[/tex]
Multiply the first numbers together.
[tex]E_p= 14.715 \ kg*m/s^2 (35 \ m )[/tex]
Multiply again.
[tex]E_p= 515.025 \ kg*m^2/s^2[/tex]
1 kilogram square meter per square second is equal to 1 Joule.Our answer of 515.025 kg*m²/s² is equal to 515.025 J[tex]E_p= 515.025 \ J[/tex]
The potential energy is 515.025 Joules.

What happens when you throw a basketball up toward the hoop? If you are lucky, the ball sinks into the net. You score two points before the ball drops down to the ground. The basketball isn’t heavy. Why doesn’t it stay up in the air when you throw it? Have you ever heard the saying, What goes up must come down? This saying helps explain what happens to the basketball. It is being acted on by an invisible force called gravity. Gravity is the force in the universe that attracts all objects to each other.
Gravity has existed since the beginning of the universe. It holds everything in the universe in place. We know it is always there. It is hard to understand how it works. First, you need to understand that there is gravitational attraction between all objects. There is gravitational attraction between you and Earth, between Earth and the Moon, and between Earth and the Sun. You cant feel the gravitational attraction between you and Earth. However, it is what keeps your feet planted firmly on the ground. Imagine spinning around and around on a merry-go-round. As long as you hold on, you will stay on the merry-go-round. Don’t let go! You will fly off and land on the ground. This analogy helps us visualize the gravitational attraction between Earth and you. Earth is spinning on its axis. Gravity keeps you on Earth rather than flying out into space.
Now think about the gravitational attraction between Earth and the Moon. The same force that keeps you on Earth pulls the Moon and Earth together. This attraction keeps the Moon in orbit around Earth. Also think about the affect of the Moons gravitational force on Earths oceans. The gravitational pull of the Moon makes the ocean tides rise and fall.
There is attraction between you and Earth and between the Moon and Earth. The Sun also has a gravitational pull on Earth. This attraction makes the Earth orbit the Sun. The Suns attraction is very strong. All objects in the solar system orbit around this medium-sized star. What would happen if the Suns gravitational attraction suddenly disappeared? All the planets, including Earth, would fly off into space just like you would if you let go of the merry-go-round.
There is gravitational attraction between all objects. Why is the effect stronger in some cases? For example, Earths gravity has a more powerful effect on you than the Suns gravity. How could this be possible? After all, the Suns gravitational attraction holds all of the objects in the solar system. The force of gravity between two objects actually depends on two things. It depends on the mass of the two objects. It also depends on the distances between them. The greater the mass of the objects, the greater the gravitational force between them. In other words, the bigger an object is, the more gravity it has. Distance also has a large effect. The closer objects are to each other, the stronger their gravitational force of attraction. As they get farther apart, the force between them gets weaker. The Sun is much more massive than Earth, but the distance between you and Earth is less. The gravitational pull of the Sun has little effect on you because the distance is so large.
Gravity is the invisible force that attracts all objects, no matter their size or mass. The Sun has the strongest gravitational force of any object in the solar system. It attracts all astronomical objects into orbit around itself. Without this force, everything would fly off into the universe.

I believe gravity is the most important aspect of our universe. Without it we would all be floating off into the universe. There wouldn’t be any orbits; instead, all planetary bodies would simply float around, running into each other when they crossed paths and just wandering forever.
There is a gravitational force between all objects in the universe. Gravitational force is what keeps all components of our solar system in orbit around the Sun, as well as moons in orbit around planets. The force of gravity affects Earth's tides and holds us on Earth's surface. The force of gravity between objects depends on their masses and the distance between them.
Gravity is hard to understand and scientists have little to no understanding of how it works. We know that gravity is out there, but the specifics are often lost on us. Plants, animals, and humans are all able to grow tall due to the pull on Earth from the Sun. Without the Sun we would all just stretch out along Earth's surface.

A net force of 16n causes a mass to accelerate at a rate of 5m/s2 determine the mass
Answer:
3.2 kg
Explanation:
From Newton's second law of motion: [tex]F=ma[/tex], where F is the force needed to give a mass m an acceleration a. Here, we have F = 16N and a = 5 m/s². Substituting those values in to our formula gives us 16N = (5 m/s²)m, and solving for mass gives us 16/5 = 3.2 N/(m/s²).
Since a Newton is defined with the units kg·(m/s²), the units of acceleration in the numerator an denominator cancel, leaving us just with units of mass, so our mass is exactly 3.2 kg.
If a ball has 300 Joules of potential energy at its highest point, how much kinetic energy will it have at its highest speed?
A; less than 300 Joules
B; more than 300 Joules
C: exactly 300 Joules
D; cannot be determined
If a ball has 300 Joules of potential energy at its highest point, Then the kinetic energy is the same at that point i.e exactly 300 Joules. The correct option is (C).
What are kinetic and potential energy?When a body has a mass of m kg and travels a velocity of v m/s then the kinetic energy is given by,
KE=1/2mv²
And when a body is at a height of h meter from the ground and the mass of the body is m kg, then the potential energy is given by,
PE= mgh
Where g= acceleration due to gravity= 9.81m/s²
At The highest point, the kinetic energy is equal to the potential energy.
i.e at the highest point,
KE=PE
Hence If a ball has potential energy at the highest point is 300J that means the kinetic energy at the point is the same i.e 300J.

You are crouched at the "start" line. Bang! The race begins and 7 seconds later you end up 60 yards down the track. What was your "acceleration?"
Answer:
a = 7.35 ft / s²
Explanation:
For this exercise we must use the kinematics relations
x = v₀ t + ½ a t²
as the runner leaves the starting line his initial velocity is zero
x = ½ a t²
a = [tex]\frac{2x}{t^2}[/tex]
let's reduce the distance to foot
x = 60 yd (3ft / 1yd) = 180 ft
let's calculate
a = 2 180 / 7²
a = 7.35 ft / s²

give three examples of the types of materials that would be used when
building houses where their thermal conductivity would need to be
considered.
Answer:
wood ,clay brick ,aluminum, and copper.
Explanation:
Three examples of types of material that would be used when building houses where their thermal conductivity are copper, aluminum, fire brick, and carbon steel.
What is thermal conductivity?Thermal conductivity is the rate at which heat is transferred from one object to another by conduction over a material's unit cross-section area.
Therefore, a substance's thermal conductivity will decrease as the distance between its atoms increases.
This is because a substance's molecules will move more randomly with the greater distance between them, which will lead to less efficient energy transfer. Metals have a much higher heat conductivity than liquids.
Therefore, copper, aluminum, fire brick, and carbon steel are three examples of materials whose heat conductivity would be employed for constructing homes.

The weight of a body is dependent on the gravitational force of its location.
WEIGHT:Weight is a force measured in Newton. It is often used interchangeably with mass, however, they are very different.
Weight refers to the mass of an object or body in relation to gravity. This means that gravity determines the weight of an object.
Weight changes as the gravitational force changes. This means that if a body is taken farther away from the surface of the earth, the weight changes because the gravitational force determines weight.
