A motorcycle starts at rest and moves a distance of 460m .
If it has constant acceleration of 4m55 m/s2 what is its final velocity
Answers
Answer:
The final velocity of the motorcycle is 64.7 m/s
Note: Since the value for the acceleration of the motorcycle is not clear, it is assumed to be 4.55 m/s² in the calculation
Explanation:
Using the equation of motion that contains all the given values in the question: v² = u² + 2as
where v is final velocity; u is initial velocity; a is acceleration; s is horizontal distance
v = ?, u = 0 (since the motorcycle starts from rest), a = 4.55 m/s², s = 460 m
v² = 0² + 2 * 4.55 * 460
v² = 4186
take square root of both sides
v = 64.7 m/s
Therefore, the final velocity of the motorcycle is 64.7 m/s

What is the enthaply of dissolution?
Answers
Answer:
The enthalpy change of solution refers to the amount of heat that is released or absorbed during the dissolving process (at constant pressure).
Explanation:
The enthalpy of solution is most often expressed in kJ/mol at constant temperature. The energy change can be regarded as being made of three parts, the endothermic breaking of bonds within the solute and within the solvent, and the formation of attractions between the solute and the solvent. An ideal solution has a null enthalpy of mixing. For a non-ideal solution it is an excess molar quantity.

a Molecules

C Pure elements
d All of the above
Answers
Answer:
D. All of the above
Explanation:
Molecules, ions, and pure elements might be included in a chemical reaction. Therefore, option (d) is correct.
What is a chemical reaction?A chemical reaction can be described as a reaction that brings the chemical conversion of one chemical substance to another chemical substance. The reactions cause chemical changes that include the rearrangement of electrons in order to create and break bonds between atoms.
The compound or molecules which are primarily utilized in a reaction are called reactants. Chemical reactions give products, which possess characteristics different from the reactants of the reaction.
Chemical reactions take place at a definite rate of reaction at a given concentration, temperature, and pressure. The rate of reaction increases with the rising temperature of the reaction as more activation energy is available for reactant molcules collisions.
Therefore, in a chemical reaction reactants and products can be present as Molecules, ions, and pure elements.

Type of Solution
Explanations about the differences of
the two solutions
Saturated solution
Unsaturated solution
Answers
Answer:
See explanation
Explanation:
A saturated solution is a solution that contains just as much solute as it can normally hold at a given temperature in the presence of undissolved solute. An unsaturated solution contains less solute than it can normally hold at a given temperature. A saturated solution can not dissolve more solute whereas an unsaturated solution can comfortably dissolve more solute until it attains saturation at a specified temperature.

Conglomerate rocks are colorful and attractive; however, it is rarely used as ornamental stone for interior use because of its unreliable physical strength and durability.
Conglomerate has very few commercial uses, though it can be crushed to make a fine aggregate that can be used when a low-performance material is needed.
Conglomerate forms where sediments of rounded clasts at least two millimeters in diameter accumulate. Because of the large size of the clasts, it takes a very strong water current to transport and shape the rocks. As they tumble through the running water or moving waves, they form their rounded shape.
These rocks can be found in sedimentary rock sequences of all ages. They probably make up less than one percent by weight of all sedimentary rocks.

There is free rotation about the carbons of ethane but not th
of ethane. This is due to the fact that
A. the carbons in ethane are round
Balkenes do not rotate
C. the carbons in ethane are linked by double bonds
D. the carbon in ethane are smaller than those of ethane
Answers
Answer:
C. the carbons in ethene are linked by double bonds
Explanation:
The reason for the lack of free rotation about the carbons of ethene is that they are linked with with double bonds.
In single bonds afforded with the ethane compound, there is free rotation.
The double bonds confer a special restriction on the rotational potential of the bonded atoms round the carbon.
