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.

How do planets with larger masses apply greater gravitational forces on objects compared to planets with less mass?
Answer:
more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.

Explanation:
In many environments, the temperature of the ground and the air right above the ground are both very similar in the middle of the night. Engineers have proposed developing a portable pop-up hammock that would allow people to sleep suspended in the air above the ground in emergencies. It will take time and money to develop a really lightweight, easy to collapse, low cost design. Before they invest the resources to do this, explain whether what you learned about energy transfer makes this an idea worth pursuing. Would suspending a person in a hammock, wrapped in one of the blankets you chose above, decrease the amount of temperature change compared to sleeping directly on the ground with one of these blankets? Explain.
Answer:
yes i think so
Explanation:
Hammock is a good idea to reduce the effect of cold in night. It is more better than sleeping directly on the ground with one of these blankets, because, the heat will transfer from us to the cool ground which make us more cool.
What is heat transfer?Heat is able to transfer from the hotter region to colder region based on the temperature gradient. The temperature gradient occurs from the difference in heat radiated in each regions.
The convection current in air occurs due to this temperature gradient. During winter seasons, the colder grounds can absorbs the heat from our body and make us cool. Thus, contact with the ground in colder nights make us more cool.
The same advantage of air circulation around your body on warm nights is provided by a nylon hammock. Additionally, a cozy under blanket (like this one from Cedar Ridge or this one from Little Shop of Hammocks) will keep your backside warm when the weather drops.

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.
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.

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?
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!

A rock is taken from the Moon back to Earth. Which of the following correctly
describes the changes to its mass and weight?
a. Its mass has no change, and its weight decreases.
b. Its mass has no change, and its weight increases.
c. Its mass decreases, and its weight has no change.
d. Its mass increases, and its weight increases
The mass of the rock remains unchanged, and its weight increases.
What is Weight ?
Weight is the force exerted by the earth on an object at the surface of the earth. Mathematically -
W = m x g
where -
m is the mass of object
g is acceleration due to gravity
Given is a rock is taken from the Moon back to Earth.
Mass and weight are completely different from each other. Mass is the amount of matter present inside the body whereas weight is the force exerted by earth on any object on its surface. Mathematically -
W = mass x acceleration due to gravity
W = Mg
The ratio of Weight to mass is [g] (9.8).
W/M = g
Mass of a body remains constant throughout the universe but its weight depends upon the value of acceleration due to gravity of the environment of the planet or any other celestial body in which it exists. Hence, because of this only, the mass of rock remains same but its weight increases as it is brought back to earth since the acceleration due to gravity on earth is greater than that on moon.
Therefore, the mass of the rock remains unchanged, and its weight increases.
