Answer:
A: In all cases, the acceleration was the same.
Explanation:
I know this because its a clear obvious answer not only that it was one of my USA TESTPREP questions and it was right.
All you mainly have to do is the math - F=ma , In each case , the acceleration is 5 m/s squared
Answer:
Potential energy: stored energy
Explanation:
Energy is the capacity to do work. It exists in various forms which can be converted from one form to another. It is measured in Joules (J).
The energy possessed by an object at rest is called potential energy. It is a form of mechanical energy. It is a stored energy which can be converted to kinetic energy when the object start to move.
The best match between an established energy type and its use or trait as given in the question is: Potential energy: stored energy
Answer:
Stress = 4.67 * 10^-7 N/m²
Explanation:
Young's modulus of the material = Stress/Strain
Given
Young's modulus = 228 x 10^9 Pa
Stress = 106,483 Pa
Required
Strain
From the formula;
Strain = Stress/Young modulus
Strain = 106,483 /228 x 10^9
Stress = 4.67 * 10^-7 N/m²
