Answer: Different ways of distributing energy have different short-term and long-term environmental consequences.
Explanation:
Due to the big issue of some energy sources being non-renewable and some being renewable, lawmakers have a lot on their plate. Non-renewable sources of energy are harmful to the environment, but they work the best. Renewable sources of energy cost a lot and work, but they require a lot of effort.
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.

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
“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.

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
Explanation:
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.

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.

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
