1. KCIO3 -> KCI - O2. Reaction Type
Answers
Answer:
thermal decomposition reaction
Explanation:
The reaction 2KCIO₃ → 2KCI + 3O₂ is a decomposition reaction. It dissociates into its constituent elements.
Decomposition reactions involve the breakdown of a compound into two or more simpler substances. In this case, potassium chlorate (KCIO₃) decomposes into potassium chloride (KCI) and oxygen gas (O₂).
The balanced equation for the reaction is:
2KCIO₃ → 2KCI + 3O₂
This reaction is typically initiated by applying heat to KCIO₃, causing it to decompose into its constituent elements.
Therefore, The reaction 2KCIO₃ → 2KCI + 3O₂ is a decomposition reaction. It dissociates into its constituent elements.

Electric cables for your lamp have a plastic rubber coating around the wire. Explain why this material surrounds the metal cable.
This is 100 points
Answers
Answer:
theyre used to prevent accidental contact with other conductors of electricity, which might result in an unintentional electric current through those other conductors.
Explanation:
Metal cables are conductor of electricity but plastic rubber coating is insulator and can not conduct current. To avoid unnecessary flow of current and safely current transmission, this material surrounds the metal cable.
What are conductor and insulator?Materials that easily permit the flow of electricity are referred to be electrical conductors. Conductivity is the quality of conductors that enables them to conduct electricity.
Insulators are substances that prevent electrons from freely moving from one elemental particle to another. The charge stays in the same spot and does not spread across the surface if we transfer any quantity of charge to such an element at any time.
Copper, aluminum, gold, and silver are a few examples of common conductors. Wood, rubber, plastic, and glass are a few typical insulators.

Describe how rainforests are more diverse than arctic ecosystems. Give examples of ecological diversity, species diversity, and genetic diversity.
Answers
Answer:
Rainforests contain around 50% of all life on Earth and only take up 6% of the Earths surface area. It contains more species of plant and animals than any other ecosystem. It's climate and geography lend it to growing more plant life which sustains many small animals. The arctic is inhospitable to most species because of the extreme cold. It's food webs do not sustain themselves well as there are fewer species at the bottom the the chain. The genetic variations are greater at the equator than the arctic giving the organisms a greater chance to survive.
Rainforests are far more diverse than arctic ecosystems because of the amount of sunlight and the rain it receives throughout the year.
What are biomes?
Biomes can be defined as regions specified by particular biological and geographical communities that evolved because of the shared regional climate of that region.
Generally, there are mainly five major types of biomes those are forest desert grassland aquatic, and tundra.
Even though they only cover 6% of the planet's surface, rainforests are home to about 50% of all living. More plant and animal species may be found there than in any other habitat.
The high temperature of the arctic makes it uninhabitable for the majority of creatures. Because there are fewer species at the base of the food chain, its food webs are unable to support themselves.
Because there are more genetic variants around the equator than in the north, species there has a better chance of surviving.
Thus, rainforests are far more diverse than arctic ecosystems.

A commercial jet liner takes off with an average acceleration of 3 g. How long does it take to reach the end of its runway which is 1524 meters away?
Answers
Answer:
The time taken for the commercial Jet liner to reach the end of its runway is 10.18 s.
Explanation:
Given;
average acceleration of the commercial Jet liner, a = 3g = 3 x 9.8 m/s² = 29.4 m/s²
distance traveled by the commercial Jet liner, s = 1542 m
The time taken for the commercial Jet liner to reach the end of its runway is calculated as follows;
s = ut + ¹/₂at²
where;
u is the initial velocity of the commercial Jet liner = 0
s = 0 + ¹/₂at²
s = ¹/₂at²
2s = at²
[tex]t = \sqrt{\frac{2s}{a} } \\\\t = \sqrt{\frac{2 \times 1524}{29.4} } \\\\t = 10.18 \ s[/tex]
Therefore, the time taken for the commercial Jet liner to reach the end of its runway is 10.18 s.

A rocket pushes exhaust 10, 000 N. Without any other forces acting on the rocket, how much force does the rocket go forward? *
Answers
Answer:
10,000 N
Explanation:
Given that a rocket pushes exhaust 10, 000 N. Without any other forces acting on the rocket, how much force does the rocket go forward?
Solution
Since there is no any other additional forces, according to Newton's 3rd law of motion which state that:
In every action there will be equal and opposite reaction.
The action expelled by the rocket through its exhaust system is of 10000N.
The reactive force will be equal and opposite which will be same -10,000 N
Therefore, the rocket will go forward with a force of magnitude 10,000 N

Answer:
, pfx = pix + Jx.
Explanation:
The momentum principle tells us that impulse transfers momentum to an object.
If an object has 2 kgm/s of momentum, a 1 kgm/s impulse delivered to the object
increases its momentum to 3 kgm/s. That is, pfx = pix + Jx.
Just as we did with energy, we can represent this “momentum accounting” with a
momentum bar chart. For example, the bar chart of FIGURE 11.6 represents the ball

the magnitude of the electrostatic force experienced by the positive charge.
a. 6.32 N
b. 2.27 N
c. 3.42 N
d. 4.45 N
Answers
Answer:
b. 2.27 N
Explanation:
Fe = (k)(Q1)(Q2) / d²
k ≈ 9 × 10⁹ N m² / C² [Coulomb's Constant] or 8.98 × 10⁹ (nearest hundredth).
q = particle charge [Coulombs; C]
d = distance [Meters; m]
Fe = Electrostatic force [Newtons; N]
________________________________
Fe = (9×10⁹)(3.5 × 10^(-8)(-4.5 × 10^(-6))/(.25)² N =
(9)(3.5)(-4.5) × (10^(9))(10^(-8))(10^(-6) / (.25)² N =
(9)(3.5)(-4.5) × (10^(9 - 8 - 6)) / (.25)² N =
(-141.75) × 10^(-5) / (.0625) N =
141.75 × 10^(-5) / (.0625) N
[opposite direction] =
(1.4175 × 10^(2)) × 10^(-5) / (.0625) N
[opposite direction] =
1.4175 × 10^(-3) / .0625 N
[opposite direction] =
1.4175 × 10^(-3) / 6.25 × 10^(-2) N =
14.175 / 6.25 N [opposite direction] =
2.268 N ≈ 2.27 N [opposite direction].
