Answer:
the tensile stress of the steel wire is 2.5 x 10³ Nm⁻².
Explanation:
Given;
applied force, F = 5000 N
cross sectional area of the steel wire, A = 0.2 m²
The tensile stress of the steel wire, is calculated as;
Therefore, the tensile stress of the steel wire is 2.5 x 10³ Nm⁻².
It would be from electrical to kinetic, so i would say a
The container that contains a greater volume of water will contain a greater mass of water.
The volume of the cube is given by:
V = s³
V = volume, s = side length
Given values:
s = 3m
Plug in and solve for V:
V = 3³
<em>V = 27m³</em>
<em />
The volume of the sphere is given by:
V = 4πr³/3
V = volume, r = radius
Given values:
r = 3m
Plug in and solve for V:
V = 4π3³/3
<em>V = 113m³</em>
<em />
The sphere contains more mass.
The efficiency of the engine at the given useful energy and input energy is 28%.
The given parameters:
- <em>Input energy of the engine, = 125 J</em>
- <em>Useful energy of the engine, 35 J</em>
The efficiency of the engine is defined as the ratio of the output energy (useful energy) to the input energy and it is calculated as follows;
Thus, the efficiency of the engine at the given useful energy and input energy is 28%.
