The correct answer is:
C. Press the gas pedal while the car is running.
A driver can cause a car to accelerate by pressing the gas pedal.
What is Acceleration?
Acceleration is the rate at which an object's velocity changes over time. It is a vector quantity that includes both the magnitude (or speed) and direction of the change in velocity. In simpler terms, acceleration refers to the rate at which an object speeds up or slows down, or changes its direction of motion.
Acceleration is caused by forces acting on an object, such as a push or pull. In the case of a car, pressing the gas pedal causes the engine to generate more power and push the car forward, resulting in an increase in velocity and acceleration. Conversely, pressing the brake pedal causes the car to slow down and decelerate.
The gas pedal controls the amount of fuel and air that is delivered to the engine, which in turn determines how fast the engine runs and how much power it generates. Other factors that can affect a car's acceleration include the car's weight, the condition of its engine and transmission, the road surface and gradient, and the driver's skills and techniques.

which nonmetal has the greatest chemical activity?
Answer:
element fluorine
Explanation:
Since the noble gases are a special group because of their lack of reactivity, the element fluorine is the most reactive nonmetal. It is not found in nature as a free element. Fluorine gas reacts explosively with many other elements and compounds and is considered to be one of the most dangerous known substances.

The _________ force between the sun and the Earth keeps the Earth in its orbit. The period of ______ is the time it takes for Earth to complete one orbit.
Question 1 options:
revolution, gravitational
rotate, gravitational
gravitational, rotate
gravitational, revolution
Gravitational force is the force between the sun and the Earth keeps the Earth in its orbit. The period of revolution is the time it takes for Earth to complete one orbit.
What is gravitational force?Gravitational force is a kind of attraction force which acts between the two bodies.
Sun's gravitational force is a 3 dimensional attraction force under which earth is present. And due to centripetal force of sun, orbit of earth is present in the stationary state. Earth revolves around the sun to complete one round of orbit and this motion is known as revolution of earth.
Hence, gravitational force is present between the sun and the earth, and revolution is the time to complete one orbit.

“Nature vs. nurture” is a debate about
A
whether a trait is learned or inherited.
B
the traits of plants vs. the traits of animals.
с
whether animals can teach humans new traits.
D
whether a trait was acquired outdoors or indoors.
Answer:
Letter A
whether a trait is learned or inherited
Explanation:
The nature versus nurture debate involves the extent to which particular aspects of behavior are a product of either inherited (i.e., genetic) or acquired (i.e., learned) influences. Nature is what we think of as pre-wiring and is influenced by genetic inheritance and other biological factors.
The debate called Nature vs. nurture is about whether a trait is learned or inherited. This is an investigation on learned traits and nurtured traits in humans. Thus option A is correct.
What are learned traits ?All living things are learning something during their growth. These learning mold up one's personality and cannot be created by birth. Like the good characteristics we are learning from schools. These behaviors are called learned traits.
Some traits or behaviors are created by birth itself and they are called natural traits. The nature versus. nurture debate is a philosophical, scientific, and cultural discussion about whether human culture, conduct, and personality are largely influenced by nature or nurture.
Environment, culture, and experience are the most prominent definitions of nurture in this discussion, whereas nature is frequently regarded as genetic or hormone-based behaviors, characteristics, and dispositions.

How many seismograph stations are needed to use the S-P-method? Why?
a minimum of three seismograph stations are needed to find an earthquake's epicenter using the S-P time method.
Scientists use triangulation to find the epicenter of an earthquake. When seismic data is collected from at least three different locations, it can be used to determine the epicenter by where it intersects. ... Knowing this helps them calculate the distance from the epicenter to each seismograph.

A volume of gas at 1.10 atm was measured at 507 ml. What will be the volume if the pressure is adjusted to 1.90
atm?
Answer:
294mL
Explanation:
We can use this equation to find the unknown volume:
[tex]P_1V_1=P_2V_2[/tex]
To solve, plug in the values we have and solve for the unknown value:
[tex](1.10atm)(507mL)=(1.90atm)V_2\\\frac{(1.10atm)(507mL)}{1.90atm} =V_2\\V_2=293.53mL[/tex]
Rounding to three significant figures gives you the value of 294mL

A gardener cut her finger while pruning shrubs. She noticed that after two weeks the wounds had nearly healed with just a small scar remaining. Which statement describes what will happen next?
A. Each one of the individual cells near the wound will grow in size to cover the injured part.
B. Cells will be transported from distant areas to the wound to cover the injured area.
C. The cells near the wound will produce identical cells by mitosis to repair the damaged tissues.
D. A material will be released by the injured cells that will cover the wound and repair the cells.
Answer:
c

The wound will be healed by the production of new cells near the wound by the cell replication process and the therefore the identical cells are produced by the mitosis to repair the damaged tissues.
Note the below points about mitosis;
The mitosis is a process in which the cell replication occurs.In mitosis, the single parent cell is divided into two identical daughter cells by the process of cell division, it takes by time.The mitosis involves the healing of wound, growth of the organisms, replacement of the worn out cells.Thus, mitosis is the process involved in the healing of wound in living beings.
Therefore, we can say that the answer of the question is C. The cells near the wound will produce identical cells by mitosis to repair the damaged tissues.

At a constant temperature the pressure on a 10.0L sample of gas is charged from 1140 torr to 1.00 atm. What is the new volume of gas sample?
Answer:
15 L
Explanation:
From the question given above, the following data were obtained:
Initial volume (V₁) = 10 L
Initial pressure (P₁) = 1140 torr
Final pressure (P₂) = 1 atm
Final volume (V₂) =?
Recall:
1 atm = 760 torr
The new (i.e final) volume of the gas can be obtained as follow:
Initial volume (V₁) = 10 L
Initial pressure (P₁) = 1140 torr
Final pressure (P₂) = 760 torr
Final volume (V₂) =?
P₁V₁ = P₂V₂
1140 × 10 = 760 × V₂
11400 = 760 × V₂
Divide both side by 760
V₂ = 11400 / 760
V₂ = 15 L
Therefore, the new volume of the gas is 15 L

If the pressure of a gas at constant volume is 4.5 atm at 100 °C, wh
will the pressure be if the temperature is changed to 350 °C?
Answer:
New pressure = 7.51 atm
Explanation:
Given that,
Initial pressure, P₁ = 4.5 atm
Initial temperature, T₁ = 100°C = 100+273 = 373 K
Final temperature, T₂ = 350°C = 350 + 273 = 623 K
We need to find the new pressure. Using the below relation as follows :
[tex]\dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}\\\\P_2=\dfrac{P_1T_2}{T_1}\\\\P_2=\dfrac{4.5\times 623}{373}\\\\P_2=7.51\ atm[/tex]
So, the new pressure is 7.51 atm.

What type of molecule would deviate the most from ideal gas behavior?
Answer:
molecule at low temperature and high pressure
Explanation:
this is because two of the postulates of kinetic theory of gases hold true only when there is low pressure and high temperature. as the pressure goes on increasing and temperature goes on decreasing, a molecule will deviate from ideal behavior.
As the temperature of a gas is increased, the average kinetic
energy of its molecules
Answer:
Increases.
Explanation:
Temperature is the measure of the average kinetic energy of a system. As temperature increases, so will kinetic energy. As kinetic energy increases, speed increases.
