Answer: true
Explanation:
In chemical reactions, an energy barrier exists between reactants and products. The magnitude of this energy barrier determines the rate of reaction. A lesser energy barrier implies that reactants are converted to products faster since the energy required is not too much. On the other hand, a large energy difference between reactants and products will lead to a slow reaction with very poor yield of products if any.
Answer:
I don't see a diagram so I am just gonna guess
Explanation:
I believe that the sample at location (E) is older. This is because it would be more down stream so I was at location (A). Where as the rock at location (A) is newer because its more up stream.
Answer:
Particle take 0.11 min to travel 158 m distance.
Explanation:
Given data:
Speed of particle = 1.5 Km/m
Distance to cover = 158 m (158/1000 = 0.158 Km)
Time taken = ?
Solution:
Formula:
s = d/t
s = speed
d = distance
t = time
Now we will put the values in formula.
1.5 Km/m = 0.158 Km / t
t = 0.158 Km /1.5 Km/m
t = 0.11 min
Thus, particle take 0.11 min to travel 158 m distance.
