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
Answers
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.

Buffalo, New York is a city located near a large lake called Lake Erie. Buffalo receives an average of nearly 94 inches of snowfall a year. Using your knowledge of temperature and what you have read, explain why Buffalo receives so much snow.
Answers
Answer: it is further away from the equator
Explanation:
The simple answer to why Buffalo receives so much snow, and why it is is often confined to a specific area, is lake effect snow. Lake effect snow occurs most frequently during cold snaps in early winter. It happens when the transfer of heat and moisture from the warm waters of the Great Lakes to the cold air creates a shallow layer of atmospheric instability, causing air to rise quickly. As the moisture rises and condenses, it begins to fall as snow–and often, a lot of snow. Depending on which direction the winds are blowing, areas in the snow belts near the Great Lakes (including Buffalo) can see several feet of snow in just a few days. According to the National Weather Service, in the Buffalo area, when cold air from Canada moves over the still unfrozen, relatively warm Great Lakes, the lake moisture and instability from this temperature contrast build one or more bands of snow. These bands are then deposited over locations downwind from the lakes, with some areas receiving much more snow than others, depending on their location and the wind direction.

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.
