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].

The appropriate question is; the correct question is:
What will be the object's final position after 5 seconds if it starts at an initial position of m and is traveling at a velocity of m/s, subject to a constant acceleration of 2 [tex]m/s^2[/tex], without any significant external forces or constraints affecting its motion?

What happens to air when it is heated by the sun?
water vapor changes to liquid
it rains
it descends
it rises
Answer:
D. It rises
Explanation:
Heat energy is released when the sun comes in to contact with the air. It then gets pushed into the atmosphere which creates a bubble of air that is warmer, causing that bubble to rise.

why are phase changes intensive properties?
Answer:
Intensive properties, such as density and color, do not depend on the amount of matter. Both extensive and intensive properties are physical properties, which means they can be measured without changing the substance's chemical identity.

Which scenario best describes motion?
A. a toy train in position 4 on a number line
B. a race track that is 100 meters long
C. a ball rolling from point A to point B
D.a student living 150 miles from Chicago
The scenario which best describes motion is a ball rolling from point A to point B as it is moving.
What is motion?Motion is defined as a phenomenon which is described with respect to change in object's position with respect to time.It is given in terms of displacement,velocity,distance ,acceleration,speed.
Branch of physics which deals with motion of objects without any reference to it's cause is called kinematics while the branch which studies forces and their effects on motion is called as dynamics.
Motion applies to various systems like objects,bodies, matter particles ,radiation ,curvature.There are three laws of motion which are proposed by Newton.Classical mechanics is based on Newton's law of motion.Relativistic mechanics is based on modern kinematics.

The figure of speech is hyperbole and through it, the reader can infer that Seabiscuit is a very fast horse.
What is a hyperbola?A hyperbole is a figure of speech that allows a term within the text to be emphasized through exaggeration. In the text above, we can see that the narrator claims that Seabiscuit is the fastest horse in the universe.
This is an exaggeration, since there are no horses in the entire universe, nor would it be possible to determine which is the fastest. However, this exaggeration serves to show the reader how fast Seabiscuit is, despite its physical structure.In the text above, we can see that the narrator claims that Seabiscuit is the fastest horse in the universe.
Therefore, The figure of speech is hyperbole and through it, the reader can infer that Seabiscuit is a very fast horse.

Use complete sentences to differentiate between acids and bases on the basis of touch. Give an example of each type.
Answer:
There are several theories to explain the difference between an acid and a base. One of the most complete theories is Lewis's theory, because it encompasses several compounds that other theories do not include. According to Lewis's theory, an acid is a substance capable of accepting a pair of electrons. And Lewis bases are substances that have the ability to donate a pair of electrons.
An example of an Lewis acid-base reaction is ammonia and boron trifluoride:
BF3 (is the acid) + NH3 (is the base) → H3N - BF3
Some differences of acids and bases to the touch are:
• Acids are sour in taste while Bases are bitter in taste. This is due to the pH that indicates acidity or basicity, and is defined as the hydrogen potential of a solution. The pH indicates the concentration of hydrogen ions in a substance. Substances with pH less than 7 are considered acidic, while substances with a pH greater than 7 are considered as bases (alkaline).
• Acids are highly corrosive, and can cause chemical burns to the skin, or respiratory damage when inhaling their gases. An example is sulfuric acid (H2SO4), which can corrode steel. The bases instead have a feeling of soap or slippery to the touch.
• Acids react with metals to produce compound and hydrogen gas while bases do not react with metals. For example, copper is attacked by nitric acid by reaction:
Cu(s) + 4HNO3(aq) ⇒ Cu(NO3)2(aq) + 2NO2(g) + 2H2O(l)
• Acids turn blue litmus paper into red whereas in case of Bases they turn red litmus paper into blue.
• The bases are irritating to the skin, as they dissolve the skin fat, and can destroy organic matter by its caustic effect. An example is Sodium Hydroxide (NaOH)
• Acid and bases are good conductors of electricity in aqueous solutions.
Explanation:
HOPE THIS HELPS
Answer:
Acids can burn your skin when touched because acids are highly corrosive, whereas bases are slimy and have a slippery feel. An example of an acid is citric acid, which can be used as a disinfectant or in foods and candies as a flavor enhancer. Bleach is an example of a base and is used for cleaning and has whitening properties.

Explanation:
If heat or energy is absorbed during a chemical reaction, then the reaction is considered:
endothermic
synthesis
combustion
exothermic
If heat or energy is absorbed during a chemical reaction, then the reaction is considered as an endothermic reaction. The enthalpy change of an endothermic reaction is positive.
What is an endothermic reaction ?The reaction in which heat energy is absorbed by the reactants is called an endothermic reaction. The enthalpy change in an endothermic reaction is positive.
The reaction in which heat is evolved from the system to the surroundings is called an exothermic reaction in which the enthalpy change is negative.
By absorbing heat energy, reactants becomes energetic enough to overcome the barrier potential of the reaction. Therefore, the potential energy diagram of an endothermic reaction will show less energy for reactants than that of products.
