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.
The correct formula to use is: F = G [M1*M2] /r^2
Where,
G = the force of gravity
M1 = the mass of the first object [the mass of the astronaut]
M2 = the mass of the second object [the mass of the planet]
r = the distance between the two objects in metre
F = 6.67 * 10^-11 [66.5 * 8.43 * 10^23] / [4.40 * 10^6]^2
F = 193N.<span />

Answer:
2m/s^2
Explanation:
we can use this formula to get the answer:
(vf - vi) / t = a
Since vf= 10m/s, vi=0m/s, and t=5
We can just substitute the values into the formula to get the result
that is:
(10 - 0) / 5 = 2m/s^2
