have the same mass were sliding across the ice. They were each pushed by a player, but not all from
the same direction. Each curling stone changed speed as a result of being hit. Use the information in
the diagram to answer.
Which curling stone(s) experienced the strongest force when hit? How do you know?
Answer:
=1200N

Usable forms of nitrogen can intentionally be increased in the soil by(1 point)
lightning.
planting more trees.
allowing organic matter to decompose.
planting fewer beans.
Usable forms of nitrogen can intentionally be increased in the soil by allowing organic matter to decompose. Therefore, option C is correct.
What is organic matter ?Organic matter is defined as anything that contains carbon compounds formed by living organisms. It includes lawn clippings, leaves, stems, branches, moss, algae, lichens, animal parts, manure, droppings, sewage sludge, sawdust, insects, earthworms, and microbes.
The majority of organic matter in soil comes from plant tissue. Plant residues have a moisture content of 60-90 percent. Carbon (C), oxygen, hydrogen (H), and trace amounts of sulphur (S), nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), and magnesium make up the remaining dry matter (Mg).
Microorganisms such as bacteria, viruses, fungi, protozoa, and algae are among the living components of soil organic matter. Plant roots, insects, earthworms, and larger animals such as moles, mice, and rabbits are also included.
Thus, option C is correct.

What is relative mass of an atom
Answer:
Explanation:
The relative atomic mass of an element is a weighted average of the masses of the atoms of the isotopes - because if there is much more of one isotope then that will influence the average mass much more than the less abundant isotope will.
Hydrogenation of double and triple bonds is an important industrial process. Calculate (in kJ) the standard enthalpy change ΔH for the hydrogenation of ethyne (acetylene) to ethane:
H−C≡C−H(g)+H2→H3C−CH3(g)
Bond enthalpies (in kJ/mol):
C−C (342)
C≡C (818.4)
C−H (403.4)
H−H (433.7)
Answer:
a
Explanation:
j
The standard enthalpy for the hydrogenation of ethyne to ethane is C−C (342).
What is Hydrogenation?Chemical reaction between a substance or element and molecular hydrogen that often occurs with the aid of a catalyst It's possible for the reaction to just involve the addition of hydrogen to a double or triple bond holding two atoms together or for the hydrogen to cause the dissociation (breaking up) of the molecule (called hydrogenolysis, or destructive hydrogenation).
Depending on the catalyst used, typical hydrogenation reactions include the reactions of hydrogen and nitrogen to produce ammonia and hydrogen and carbon monoxide to produce methanol or hydrocarbons.
In the presence of a catalyst, nearly all organic molecules having numerous bonds connecting two atoms can react with hydrogen.
Therefore, The standard enthalpy for the hydrogenation of ethyne to ethane is C−C (342).

The starting position of this object is m. The object is traveling at a velocity of m/s.
Answer:
The starting position of this object is 3 m
The object is traveling at a velocity of 3 m/s
Explanation:
The object's final position after 5 seconds, starting from an initial position of m with a velocity of m/s and constant acceleration of 2 [tex]m/s^2[/tex], is given by s = 5m + 50[tex]s^2[/tex] m.
To find the object's final position after 5 seconds, we can use the following equation of motion:
[tex]\[ s = ut + \frac{1}{2}at^2 \][/tex]
where:
- [tex]\( s \)[/tex] is the final position,
- [tex]\( u \)[/tex] is the initial velocity,
- [tex]\( t \)[/tex] is the time, and
- [tex]\( a \)[/tex] is the acceleration.
Given:
Initial position [tex](\( s_0 \))[/tex] = m
Initial velocity [tex](\( u \))[/tex] = m/s
Acceleration [tex](\( a \)) = 2 m/s\(^2\)[/tex]
Time [tex](\( t \))[/tex] = 5 s
Substituting these values into the equation, we have:
[tex]\[ s = (m/s) \times (5s) + \frac{1}{2} (2 \, \text{m/s}^2) \times (5s)^2 \][/tex]
Simplifying further:
[tex]\[ s = 5m + \frac{1}{2} \times 2 \, \text{m/s}^2 \times 25s^2 \][/tex]
[tex]\[ s = 5m + 2 \, \text{m/s}^2 \times 25s^2 \][/tex]
[tex]\[ s = 5m + 50s^2 \, \text{m} \][/tex]
Therefore, the object's final position after 5 seconds is [tex]\( s = 5m + 50s^2 \, \text{m}\)[/tex].

magnesium reacts with oxygen and forms magnesium oxide , for example
Answer: When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide, which is a compound. ... After it burns, it forms a white powder of the magnesium oxide. Magnesium gives up two electrons to oxygen atoms to form this powdery product. This is an exothermic reaction.

D. Flagellum
In the given diagram, the structure labeled with an arrow is the nucleus. Therefore, option (B) is correct.
What is the nucleus of a cell?The nucleus is the most integral component of the cell. A nucleus can be defined as a double-membraned eukaryotic cell organelle that consists of genetic material.
The nucleus is typically the most evident organelle in the cell. The nucleus is entirely bound by membranes and is surrounded by the nuclear envelope.
The contents of the nucleus distinguish from the cytoplasm by the membrane. The nucleus contains hereditary information about the cell and controls its growth and reproduction.
The nucleus is not just a storage section for DNA but also occurs to be the home of cellular processes. In the nucleus, DNA can be duplicated and the process is named as named DNA Replication and produce an identical copy of the DNA.

5. When a copper metal is exposed to moist air for a long time,then a green coating is formed on its surface .What is the green material formed on its surface. Support your answer with word equation.Is it acidic or basic in nature.
PLEASE HELP ME !!!!
Answer:
A. oxygen
B. chlorine
2. iodine
(a) because aluminium is a soft malleable metal. it can be made to in sheets to form thin wrapping sheets. also, it does not react with food items.
(b) because metals are good conductors of heat and electricity. the immersion rod needs electric supply to get heated and to heat liquids.
(c) they're kept in kerosene to keep them from coming in contact with oxygen and moisture as they react to form their hydroxides.
4. Magnesium is a metal. Metals react with oxygen to form metallic oxides. So Magnesium oxides are basic in nature. But nonmetals react with oxygen to form nonmetallic oxides. These oxides differ from metallic oxides because they are acidic in nature. Nonmetallic oxides react with water to form acids. Therefore, Sulphur dioxide is acidic in nature. Magnesium oxide is basic in nature.
5. Copper forms a green deposit on its surface when exposed to air which is usually a mixture of copper carbonate and copper hydroxide. It's acidic in nature.
