Answer: KL
Explanation:
The side of Figure T' that is congruent to side 1 of Figure S using relevant transformations is; KL.
How To Carry out Rotational Transformation?When rotating a shape 90° clockwise, it is expressed as;(x, y) → (y, -x).
When reflecting the image over the y-axis, it is expressed as (x, y) → (-x, y).
Carrying out the two transformations would mean that we are reflecting a shape over the y = -x line, where;
(x, y) → (-y, -x).
Thus, the side of Figure T' that is congruent to side 1 of Figure S is KL.

Explanation:
When Barium chloride is formed, what questions will the student need to know prior to making the formula???
Answer:
Valency of the two elements
Explanation:
In order to correctly formularize the compound, the student needs to ask of the valences of the elements involved.
Chlorine has valency of -1, while Barium +2.
The exchange of valency gives the formula [tex]BaCl_{2}[/tex].
Another explanation is that Barium donates 2 electrons which the chlorine atoms accept, in order to form the covalent bond.

The volume of a gas is 450 mL when its pressure is 1.00 atm. If the temperature of the gas does not change, what is the pressure when its volume is changed to 2.00 L?
Use P Subscript 1 Baseline V Subscript 1 = P Subscript 2 Baseline V Subscript 2.
0.225 atm
0.444 atm
2.25 atm
4.44 atm
Answer:
0.225 atm
Explanation:
v1=450ml÷1000=0.45l(1l=1000ml)
P1=1
v2=2.00l
p2=?
p1v1=p2v2
p2=p1v1/v2
=1×0.45/2
=0.225
so the answer is first one
This question is based on Boyle's law as temperature is constant. Boyle's law is derived from ideal gas equation only at constant temperature. Thus the pressure calculated is 0.225atm.
What is Boyle's law?
Boyle's law is a law which states that at constant temperature, the pressure that is exerted by an ideal gas on the walls of the container is inversely proportional to the volume occupied that gas.
Ideal gas is a gas where there is no forces of attraction or forces of repulsion between the particles . The volume of container is equal to the volume occupied by the gas.
Mathematically,
Initial condition to final condition
[tex]P_{1}V_{1} \rightarrow P_{2}V_{2}[/tex]
[tex]P_{1}[/tex]=1.00atm
[tex]V_{1}[/tex]=450 mL=0.45l
[tex]P_{2}[/tex]=?
[tex]V_{2}[/tex]=2.00L
Substituting all values in given equation
[tex]P_{1}V_{1} \rightarrow P_{2}V_{2}\\P_{2}=P_{1}V_{1}\div V_{2}[/tex]
[tex]P_{2}[/tex]=(1×0.45)÷2.00
[tex]P_{2}[/tex]=0.225atm
Thus the pressure when volume changed to 2.00 is 0.225atm.

A student uses a force of 46 Newtons to push her bike 57 meters. How much work has she done?
W = F x D
Answer:
The displacement is 0.05 meters. The angle between the upward force and the upward displacement is 0 degrees. The work for 1 push-up is approximately. W = 10 N * 0.05 m * cos 0 degrees = 0.5 Joules. If the squirrel does a total of 5.0 Joules of work, then it must have done about 10 push-ups.

How is a mixture different from a compound?
a. Mixtures have 2 or more components
b. Mixtures are commonly found in nature
c. Solids, liquids, and gases can form mixtures
d. Each substance in a mixture keeps most of its characteristic properties
Answer:
d. Each substance in a mixture keeps most of its characteristic properties
Explanation:
Compound is formed by the fixed composition of two or more substances while mixture is formed by the different composition of two or more substances.
Compound and mixture are different from each other as each substances in mixture shows its own properties while compounds shows a different new properties.
Hence, the correct answer is "d".
Four oranges were placed in a series circuit. Approximately what voltage did this produce?
Answer:
Four times the original amount if only one orange was used
Explanation:
We can assume that the oranges all have equal voltages. Connecting them in series will have an increasing effect on the voltage delivered. In our case, this will produce 4 times the voltage of the circuit when only one orange is used.
Whenever simple cells are connected in series, the voltages of the individual cells are added up to form the voltage of the whole circuit.
Let us assume that the voltage of each of the oranges is approximately 0.9 volts. The Voltage produced when the 4 oranges are joined in series is 0.9 + 0.9 + 0.9 + 0.9 = 3.6 volts

Which of the elements has the same Lewis dot structure as calcium (Ca)?
A.Barium (Ba)
B.Potassium (K)
C.Germanium (Ge)
D.Argon (Ar)
Answer:
[tex]\boxed {\boxed {\sf A. \ Barium (Ba)}}[/tex]
Explanation:
Lewis dot structures illustrate the valence electrons in an element.
Valence electrons are the outermost electrons in an atom that bond with other atoms by accepting or releasing electrons. The groups, or columns, of the Periodic Table have the same number of valence electrons.Calcium is in group 2.
The other elements in this group are:
Beryllium, Magnesium, Strontium, Barium, and RadiumSo, all these elements have the same lewis dot structures because they have the same number of valence electrons.
Based on the answer choices, choice A is correct.

Answer: 1. Actually, mass does not affect velocity. The sum of all forces that act on the object causes the acceleration a while the mass m resists it.
2. just say it's the force into the height that it covers from one point to another. ... (a) At point .
Explanation:
The problem is about Conservation of Energy, between Potential Energy and Kinetic energy changes.
Given is friction-less roller coaster. it is also assumed that there is no loss of energy due to air friction.
And so regardless of what path the ball takes, the work done by gravity doesn't depend on the path, it only depends upon the height through which it falls.
3. The principle of the conservation of mechanical energy states that the total mechanical energy in a system (i.e., the sum of the potential plus kinetic energies) remains constant as long as the only forces acting are conservative forces.
What is “the process in which electrons are rearranged without direct contact”???
Answer:
Induction
Explanation:
The process whereby electrons are rearranged without direct contact with one another is called induction.
By induction electrons can get charged without them having to be in contact with one another.
When a charged body is brought to the vicinity of the electrons, either an attraction or repulsion force is set up. Similar charges causes repulsion If a negatively charged body is brought near the electrons, there would be heavy repulsion and the electrons would be forced to rearranged. This effect is product as a result of a force field.Ducks and geese have small, fluffy feathers called "down."

What is the specific heat of a 123 g substance that requires 4.56 J of heat in
order to increase its temperature by 12.32 °C?
A) 0.00301 J/g °C
B) 0.457 J/g °C
0 6910 J/g °C
D) 2.19 J/g °C
E) 0.0220 J/g°C
Answer: A. [tex]0.00301J/g^0C[/tex]
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
[tex]Q=m\times c\times \Delta T[/tex]
Q = Heat absorbed = 4.56 J
m = mass of substance = 123 g
c = specific heat capacity = ?
Change in temperature ,[tex]\Delta T=T_f-T_i=12.32^0C[/tex]
Putting in the values, we get:
[tex]4.56J=123g\times c\times 12.32^0C[/tex]
[tex]c=0.00301J/g^0C[/tex]
The specific heat of a 123 g substance that requires 4.56 J of heat in order to increase its temperature by 12.32 °C is [tex]0.00301J/g^0C[/tex]

When solid converts to gas then heat is required to break the intermolecular forces of attraction between the particles. In this process heat increase but temperature remains the same. Therefore, the correct option is option C.
What is phase transition?Phase transition is a process in which transition takes place from one state to another of a medium on changing temperature or pressure. Phase transition is a physical process as there is no breaking of old bond and forming of new bonds takes place.
During phase transition temperature remain constant as the extra heat that is given to the system that goes into breaking of intermolecular forces of attraction between the particles. So overall temperature remains same but heat keeps on increasing. Among all the given option, expansion is the only process in which change of state does not take place.
Therefore, the correct option is option C.
