Explanation:
Activation energy and reaction rate
The activation energy of a chemical reaction is closely related to its rate. Specifically, the higher the activation energy, the slower the chemical reaction will be. ... The released energy helps other fuel molecules get over the energy barrier as well, leading to a chain reaction.
Answer:
g ≈ 7.4 m/s²
Explanation:
The acceleration due to gravity on planet XX is ...
g = GM/r² = (6.67·10^-11 × 4·10^22)/(6·10^5)^2
g ≈ 7.4 m/s²
Main Answer:
Assume that the temperature rises by 9.9 F
Initial Temperatures will be C1, F1
Final temperatures will be C2, F1 + 9.9
The relation between celsius and fahrenheit temperature is as follows:
C = 5/9(F - 32)
Increase in temperature in celsius will be
C2 - C1 = F2 - F1
C2 - C1 = 5/9 ( F1 +9.9 -32) - 5/9 ( F1 -32)
C2 - C1 = 5/9 ( F1 +9.9 -32 - F1 +32)
C2 - C1 = 5/9 (9.9)
C2 - C1 = 5.5C
Explanation:
What is temperature?
Temperature is defined as the degree of coldness or hotness of an object or a substance. Generally, it is measured in various temperature scales. They are celsius, fahrenheit, kelvin.

Answer:
Speed; v = 17 m/s
Explanation:
We are given;
Radius; r = 110m
Angle; θ = 15°
Now, we know that in circular motion,
v² = rg•tanθ
Thus,
v = √(rg•tanθ)
Where,
v is velocity
r is radius
g is acceleration due to gravity
θ is the angle
Thus,
v = √(rg•tanθ) = √(110 x 9.8•tan15)
v = √(288.85)
v = 17 m/s
