Answer:
153.6 kN
Explanation:
The elastic constant k of the block is
k = E * A/l
k = 95*10^9 * 0.048*0.04/0.25 = 729.6 MN/m
0.12% of the original length is:
0.0012 * 0.25 m = 0.0003 m
Hooke's law:
F = x * k
Where x is the change in length
F = 0.0003 * 729.6*10^6 = 218.88 kN (maximum force admissible by deformation)
The compressive load will generate a stress of
σ = F / A
F = σ * A
F = 80*10^6 * 0.048 * 0.04 = 153.6 kN
The smallest admisible load is 153.6 kN
The answer to your question will be C. because they are very inexpensive and are readily available but they will eventually deplete because we use them faster than they can be produced we use what has been building up.
Answer:
Examples include cars, buildings, clothing, and tools. Nonmaterial culture refers to the abstract ideas and ways of thinking that make up a culture. Examples of nonmaterial culture include traffic laws, words, and dress codes.
Answer:
f = 23.64 Hz
Explanation:
From the wave equation, the relationship between frequency and wavelength is given by;
f = cλ
Where;
λ is wavelength
c is speed of light with a constant value of 3 × 10^(8) m/s
f is frequency
We are given wavelength of 7.88 x 10^(-8) m
Thus;
f = 7.88 x 10^(-8) × 3 × 10^(8)
f = 23.64 Hz
Answer:32.7
Explanation:
You must first make a right triangle with the two legs being 17 m west and 26.5 m north. To find the degree measurement west of north you must find the angle between the north leg and the hypotenuse. then just use inverse tangent of (17/26.5) which is 32 .7 degrees
