Okay, so what temperature does is increase the speed of particles (their kinetic energy). This means that a higher percentage of particles are going to have the required energy (activation energy) to cause a reaction. This however does not actually change the activation energy; all it does is change the amount of particles that HAVE the activation energy. hope that helped
4. Dark Energy.
This is the mysterious force causing the expansion of space. No one has ever seen this force.
Answer:
Mineral Wool
Explanation:
The mineral wool is a porous material that restricts thermal energy by trapping air in.
The kinetic energy K = 0.5 * m * v² must be equal to the potential energy U = m * g * h.
m mass
v velocity
h height
g = 9.81m/s²
The mass m cancels out:
0.5 * v² = g * h
Solve for height h and transform to distance traveled.
(sin (4°) = height / distance)
