Answer:
31.67 in
Explanation:
Given:
Diameter of the pipe, D = 3ft = 36 in
cross-sectional area of the steel = 0.2 in²
Note: Refer to the figure attached
From the free body diagram represented in the figure, we have
ΣFx = 0
or
pressure × projected area = 2 × Force in steel
Now, the projected area = spacing (s) × diameter of the wood pipe
force in steel = stress in steel (σ) × cross-sectional area of the steel
on substituting the values we get
4 ksi × (s × 36 in) = 2 × σ × 0.2 in²
also, allowable hoop stress = 11.4 ksi
thus,
σ = 11.4 ksi = 11.4 × 10³ psi
therefore, we have
4 psi × (s × 36 in) = 2 × 11.4 × 10³ psi × 0.2 in²
thus,
s = 31.67 in
hence the maximum spacing is 31.67 in
The circumference of a circle with a diameter of 10 cm is 31.4cm.
The circumference of a circle is its edge or the measurement of its entire arc.
The circumference of a circle with radius 
is 
.
The circle in question has a diameter of 10 cm.
The radius of a circle's diameter is equal to its length divided by two. Consequently, the given circle's radius is 5 cm.
If we assume that π=3.14, then the given circle's circumference will be equal to 2×π×5. Consequently, 31.4 cm is the required circumference.
As a result, a circle with a diameter of 10 cm has a 31.4 cm circumference and it has been expressed in three significant figures.

Answer:
Answer to the following answer is as follows;
Explanation:
In the northwestern city of Milan, Mussolini formed his nationalist regime in 1919. He organised black-shirted street warriors into teams. His "Blackshirts" raped and expelled socialists and communists from municipal administrations.
The Blackshirts, originally known as the Squadrismo, were formed in 1919 by a group of dissatisfied former soldiers.
Answer:
a) The velocity is maximum at B.
b) The velocity is 0 at C and A.
c) The acceleration will be 0 at B
d) The acceleration is maximum at C and A.
Explanation:
In the attached image, we can see two sketches the first one is based on the principle os energy conservation and we can appreciate easily when the velocity is the greatest and when it will be 0.
In points A and C we have the maximum potential energy because the pendulum is at the highest elevation with respect to the reference point. And when the pendulum is in point B all the potential energy had been transformed into kinetic energy and therefore we will have the maximum velocity at this point.
For the acceleration analysis, we see the second sketch, this one is showing a free body diagram of the pendulum when it is forming a theta angle with respect to the vertical plane. And applying Newton's second law and contemplating the forces that are acting over the pendulum we have the equation showed in the image.
This equation shows that the acceleration which has the same direction as the velocity depends on the sin(theta) and we know that the equation will be zero (0) when the angle theta is 0. It means the acceleration will be 0 at point B. And maximum at points C and A.
Answer:
Mental time travel has been studied by psychologists, cognitive neuroscientists, philosophers and in a variety of other academic disciplines. Major areas of interest include the nature of the relationship between memory and foresight, the evolution of the ability (including whether it is uniquely human or shared with other animals), its development in young children, its underlying brain mechanisms, as well as its potential links to consciousness, the self, and free will.
