Answer:
14 m
Explanation:
Applying,
P.E = WH............ Equation 1
Where P.E = potential energy at the highest vertical height, W = weight of the toy rocket, H = Vertical height.
Note: At the highest vertical height, the kinetic energy is 0 J
Therefore,
Mechanical energy(M.E) = Potential Energy(P.E)
make H the subject of the equation
H = P.E/W......... Equation 2
From the question,
Given: W = 10 N, P.E = 140 J
Substitute these values in equation 2
H = 140/10
H = 14 m
Answer:
We can cause delamination.
Explanation:
The reason why is because the probability of causing delamination increase considerably when we use Hole-filling fasteners. If we use a typical rivet, these tends to expands in order to fill the hole.
If we analyze the force applied by the expanded rod will cause that the matrial will be deteriorated and will cause that the material to delaminate around the edges of the hole and we can cause possible control and no protection to the material.
Answer:
i believe it's carbon. i may be wrong. but i haven't done atoms in almost 2 years. sorry if it's wrong. :)) hava good day
