Answer:
Centripetal acceleration of the wheel is
.
Explanation:
We have,
Diameter of a Ferris wheel is 60 m
Radius of the wheel is 30 m
Speed of the wheel is 2.09 m/s
It is required to find the centripetal acceleration of the wheel. The formula of centripetal acceleration is given by :

So, the centripetal acceleration of the wheel is
.
Answer:
Electronegativity is probably the biggest thing that plays into reactivity. Therefore, since fluorine has a higher electronegativity than chlorine, fluorine is more reactive.
Explanation:
I got it right
Answer:If a bouncing ball has a total energy of 20 J and a kinetic energy of 5 J, the ball’s potential energy is 15J.
If the kinetic energy of the ball decreases, then the potential energy will Increase.
Explanation:
Answer:
54.075KJ
Explanation:
Since methane is the limiting reactant.
From the reaction equation,
16 g of methane absorbs 206 KJ of energy
4.20 g of methane will absorb 4.20 × 206/16 = 54.075KJ of energy was absorbed.
From the equation, the value of the enthalpy of reaction is positive, this means that energy is absorbed in the reaction of methane and water. Hence the answer.
Answer:
Combustion reaction
General Formulas and Concepts:
<u>Chemistry</u>
- Synthesis Reactions: A + B → AB
- Decomposition Reactions: AB → A + B
- Single-Replacement Reactions: A + BC → AB + C
- Double-Replacement Reactions: AB + CD → AD + BC
Explanation:
<u>Step 1: Define</u>
2C₂H₂ + 5O₂ → 2H₂O + 4CO₂
<u>Step 2: Identify</u>
Any organic molecule reacting with oxygen to produce water and carbon dioxide is a combustion reaction.
We also see from the RxN that is is a double replacement reaction.
