Answer:
Potential,Kinetic
Explanation:
When an object is higher up on a surface it has more Gravitational Potential Energy whilst when an object is lower down but moving fast it has more kinetic energy. So when the object moves down the ramp energy is transferred from the gravitational potential energy store to the kinetic energy store.

what is the acceleration of 1 m/s?
Answers
Answer:
Newton es la fuerza que provoca una aceleración de 1 m/s2 en un cuerpo de 1 kg. La segunda ley de Newton establece que la fuerza y la aceleración son directamente proporcionales, pero no hay que olvidar el efecto de la masa.

Which option correctly describes the pattern of valence electrons on the periodic table?
O The number of valence electrons increases from right to left
O The number of valence electrons increases from bottom to top.
O The number of valence electrons increases from top to bottom
O The number of valence electrons increases from left to right.
Answers
Answer:
O The number of valence electrons increases from left to right.
Explanation:
In general, the number of valence electrons is the same within a column/group. When the group number increases, the # of valence electrons also increases.
The option correctly describes the pattern of valence electrons on the periodic table is the number of valence electrons increases from left to right. Thus, option D is correct.
What is atomic mass?In universe every particle have some mass associated with it whether it is small or large. According to Dalton's theory of atomic structure every particle is made up of with atoms. The average mass of atomic particle is called as atomic mass. This is commonly calculated as per international agreement in terms of a unified atomic mass (amu).
It can also be defined as 1/12 of the mass of a carbon atom-12 in its ground state. The mass of atom can also be calculated as the mass of protons and neutrons which almost equal to atomic mass. This small change is due to the binding energy mass loss.
Calculation:-
As per given above question:-
99% H-1
0.8% H-2
0.2% H-3
So,
Atomic mass = (99x1 + 0.8x2 + 0.2x3)÷100%
Atomic mass = 1 amu,
Therefore, The option correctly describes the pattern of valence electrons on the periodic table is the number of valence electrons increases from left to right. Thus, option D is correct.

1) Would a person's weight on Earth be the same as it would be on the moon? Explain using the key words weight, mass & gravity.
Answers
Answer:
The force gravity exerts on a person determines the person's weight. Even though your mass would be the same on Earth and the moon, if you weigh 132 pounds (60 kilograms) on Earth, you would weigh about 22 pounds (10 kilograms) on the moon.

• Acceleration: change in velocity compared with the time it takes to change
- Average Acceleration: (Final Velocity - Starting Velocity) / Time
• Velocity: expressed in meters per seconds (m/s)
• Time: expressed in seconds (s)
• Acceleration is measured in meters per second per second
- meters per second squared (m/s²)
Picture #2:
• Acceleration is a vector
- magnitude
- direction
• Acceleration: increases and decreases in speed
• Positive Acceleration: increase in speed
- sliding down from a hill
- small velocity -> large velocity
• Negative Acceleration: decrease in speed
- car slowing then
- high velocity -> low velocity
- initial velocity is larger than final velocity
- (v2 - v1) will be negative
- acceleration “a = (v2 - v1) / t” will be negative
• Acceleration and velocity (rate of motion) in the same direction = speed will increase.
• Acceleration and velocity in opposing directions = speed will decrease
Picture #3:
• Acceleration: rate at which velocity changes
• Velocity is a vector: has magnitude & direction
- magnitude or direction changes = the velocity changes
• Object accelerates speed = direction of motion or both magnitude and direction changes
• Acceleration depends on amount of time for the change to take place and how much velocity changes
- Small change in velocity can be a large change in acceleration if the change occurred quickly.
- Large change in velocity can be a small change in acceleration if the change occurred slowly.
- Increasing speed by 5 m/s in 5 seconds is smaller acceleration to increase speed by 5 m/s in 1 second.
Picture #4:
• An object changing the direction of motion experiences acceleration even when not speeding up or slowing down
• An object is always turning.
• Centripetal Acceleration: acceleration in circular mode.

think about the statement "every decision has an environmental impact"?what decision do you make that add carbon dioxide to the environment?what decision do you make that would add less carbon dioxide to the environment then you currently add?
Answers
Explanation:
Certain actions and/or their method can affect the environment, such as leaving the sink on while brushing your teeth or not turning off a light when you leave the room. I personally make decisions to prevent my association with Greenhouse gases by turning off lights when I leave a room, using minimal water, recycling, etc.
Answer:
Answers may vary. View explanation.
Explanation:
There are every day decisions that may add carbon dioxide to the environment.
Problems:
Burning of fossils fuels. Example: Using cars as transportation. The average car releases around 4.6 metric tons of carbon dioxide per year.Deforestation. Carbon dioxide is released from dead organisms such as trees. Example: As of 2021, 15 billion trees are lost to deforestation.Solutions:
Instead of taking your car to work or school, carpool with a friend. Riding your bike and taking the bus are also good solutions that help minimize carbon dioxide releases.In spare your time, grab a couple of friends and plant some trees! Even planting just a few trees is a great start to help the planet.Have a great day!
