Answer:
E = 1.25×10¹³ N/m²
Explanation:
Young's modulus is defined as:
E = stress / strain
E = (F / A) / (dL / L)
E = (F L) / (A dL)
Given:
F = 10 kg × 9.8 m/s² = 98 N
L = 1 m
dL = 10⁻⁵ m
A = π/4 (0.001 m)² = 7.85×10⁻⁷ m²
Solve:
E = (98 N × 1 m) / (7.85×10⁻⁷ m² × 10⁻⁵ m)
E = 1.25×10¹³ N/m²
Round as needed.
Answer:
Explanation:
Near the earth's surface where gravity is approximately 10 m/s² downward
v = u + at
v = 5 + (-10)(1) = -5 m/s
so it has the same speed but in the opposite (downward) direction.
Answer:
<h2>D. erosion of the rule of law.</h2>
Explanation:
This can be described as an erosion of the rule law, because this type of policies is offering a huge gap inside the law, it can be distorted is such many ways, that at some point it won't represent an actual functional law. The subjectivity behind <em>"to avoid testifying in trials if they declare that their testimony could damage national security or interests" </em>is too much. A member of the legislature could avoid testifying into important cases just with the excuse that is national security.

Answer:
100 W
Explanation:
The power can be defined as energy change / time taken
Or
Energy used/time taken
So in this case you get,
Power = 2500/25 = 100 W
