I think the correct answer from the choices listed above is the second option. For endothermic reactions, the reactants have less energy than the products. Which would mean that energy should be added to the reaction for it to proceed. Hope this answers the question.
Constantine I helped to socially and politically unify the early byzantine empire by tolerating and even promoting christianity.
Answer:
10.87 m
Explanation:
Total length of the wire = 25 m
Let the length of one piece is y and other piece is 25 - y
Let the side of square is a.
So, 4 a = y
a = y / 4
And the side of triangle is b
3 b = (25 - y)
b = (25 - y) / 3
Area of square, A1 = side x side =
A1 = y² / 16
Area of equilateral triangle, A2 =
Total area, A = A1 + A2
For maxima and minima, fins dA /dy
It is equal to zero.
9y = 173.2 -6.928 y
15.928 y = 173.2
y = 10.87 m
So, the length of wire to make square is 10.87 m.
A calorimeter measures the amount of heat in a chemical reaction. So the answer would be C, specific heat.
Answer:
Annihilation
Explanation:
Annihilation is the phenomenon that occurs when a particle of matter and its corresponding anti-particle of antimatter collide with each other. When this collision occurs, the particle and antiparticle "disappear", and all their mass is converted into pure energy, according to Einstein's famous equation:
where
E is the energy released
m is the mass of the two particles together
c is the speed of light
Annihilation is the process that releases the largest amount of energy at all, since the whole mass of the particles involved is 100% converted into energy. An example of annihilation is the electron-positron annihilation.
