According to the Boyle's law, as pressure is inversely proportional to volume at constant temperature the the new volume of gas is 40 ml.
What is Boyle's law?Boyle's law is an experimental gas law which describes how the pressure of the gas decreases as the volume increases. It's statement can be stated as, the absolute pressure which is exerted by a given mass of an ideal gas is inversely proportional to its volume provided temperature and amount of gas remains unchanged.
Mathematically, it can be stated as,
P∝1/V or PV=K. The equation states that the product of of pressure and volume is constant for a given mass of gas and the equation holds true as long as temperature is maintained constant.The nature of graph obtained when gas obeys Boyle's law is hyperbolic curve.

Name 2 types of electric circuits based on their connection pattern
Answer:
When there are two or more electrical devices in a circuit with an energy source, there are a couple of basic ways by which we connect them. They can either be connected in series or parallel
[tex]\huge\bold\green{Answer:-}[/tex]
Series Circuit:-A series circuit has only one path for electricity to flow from one point to another. The amount of electricity in the circuit is consistent throughout any component in the circuit. When electricity flows through a series circuit, its rate of flow (speed) will never fluctuate. The total resistance of a series circuit equals the sum of individual resistances. The more resistors that a series circuit has, the more difficult it is for electrons to flow.
Parallel circuit:-A parallel circuit has multiple paths for electricity to flow from one point to another. According to website All About Circuits, “all components are connected between the same set of electrically common points.” Often, resistors and sources will be connected between two sets of electrically common points. In a parallel circuit, electricity can flow in multiple directions horizontally and vertically. The components of a parallel circuit will have the same voltage across their ends and will have identical polarities.

an object falls from a high building and hits the ground in 9.0 seconds.ignoeing air resistance,what is the distance that it fell?
Answer:
kinematic eq. d = Vi*t + 1/2a*[tex]t^{2}[/tex]
Explanation:
Vi=0
d=1/2 a*[tex]t^{2}[/tex]
d= 1/2(9.8)[tex]0.9^{2}[/tex]
d=3.969 m
The distance from which the object falls is 393.9 meters.
Given that, an object falls from a high building and hits the ground in 9.0 seconds and air resistance = 0
So the distance can be calculated by the formula given below.
[tex]s = vt + \dfrac{1}{2} at^2[/tex]
Where, [tex]s[/tex] is the distance in meters, [tex]t[/tex] is time (in seconds) taken by the object in motion, [tex]a[/tex] is the acceleration of the object in meter per second square and [tex]v[/tex] is the final velocity in meter per second.
In this case, object falls from high building to the ground so the final velocity would be zero. Gravitational acceleration is -9.8 meter per second square.
Substituting the values in the above formula,
[tex]s = (9.0\times0) + \dfrac{1}{2}(-9.8\times(9.0)^2)\\s = 0 + (-9.8\times81\times0.5)\\s = 396.9 \;\rm m[/tex]
The distance from which the object falls is 393.9 meters.

Answer:
m = 68,486,6 g is the answer.
Explanation:
To calculate mass you use formula:
m= V*r
To avoid remembering this formula you can see the type of unit on each given variable. We can see that we have g/cm^3 and cm^3. If we multiply them, we negate cm^3 and cm^3 and we are left with g which is unit for mass.

Describe a ways car manufacturers try to reduce drag and why.
Aerodynamics is a way to reduce drag that uses car manufacturers.
What is aerodynamic ?
Aerodynamics is the motion of the air. airplane flies cause of aerodynamics.
Aerodynamics is the study of forces that are resulted by motion of the air.
To reduce the aerodynamic drag further, the manufacturers use character lines on the exteriors of the car's body right from its concept stage. These lines help the air to pass smoothly over the body and thus, reducing the air resistance.
cars have flat vertical face in front. When it moves through air, drag force directly proportional to the velocity applies on the car which opposes motion of the car. after studding aerodynamics when we make triangular like shape to the front body of the car, it cuts the air and front air goes from side of the car which reduces oppose to the motion, and car can have more speed.

A dog walks 21 m north and then walks 35 m west to bury a bone. What is the displacement of the dog?
Answer:
40.8 m North West.
Explanation:
Please see attached photo for diagram.
In the attached photo, R represent the displacement of the dog.
The displacement (R) of the dog can obtained by using the pythagoras theory as illustrated below:
R² = 35² + 21²
R² = 1225 + 441
R² = 1666
Take the square root of both side.
R = √1666
R = 40.8 m North West.
Therefore, the displacement of the dog is 40.8 m North West.

John can't describe a penny because he never learned what one looked like in the

John and Susan find a penny, and Susan says, "I bet you can't tell me what is on the penny". John's inability to describe the penny is an example of a failure to encode.
The ability to encode a piece of information is to be able to translate or explain the body of information at a later date or time. When John thinks about what is on the penny, he couldn't describe it because he never learned how to encode the information on the piece of the penny in the first place.
Retroactive interference is a process whereby fresh memories interfere with the recovery of old memories. This sort of interference has a retrograde impact rendering it more challenging to recall previously learned information.
On the other hand, proactive interference is a process whereby old memories interfere with the recovery of fresh new memories.
Therefore, we can conclude that since John has never learned what a penny looked like before, he doesn't have previous information about it. As such, the only correct option is (2)
