(a) Leak before break is a concept of designing the system or structure to minimize the risk of sudden catastrophic failure due to cracks.

The concept is to create a design that allows the development of cracks, and before the crack gets to a critical size, the system or structure should be able to detect the crack or leak. There are three stages in a leak-before-break condition:

First stage - Crack initiation: In this stage, cracks start to develop, but there is no effect on the system or structure's performance.

Second stage - Slow Crack Growth: In this stage, the crack's growth is slow, and the crack's effects on the system or structure are minimal.

Third stage - Rapid Crack Propagation: In this stage, the crack grows rapidly, and it could cause a catastrophic failure of the system or structure.  

(b) Longitudinal stress, σl = (pi x di^2)/4tσl = (28.75 x 10^6 x (0.08^2))/4 x 0.01σl = 58000000 Pa Hoop stress, σH = (pi x di x p)/2tσH = (28.75 x 10^6 x 0.08)/2 x 0.01σH = 11500000 Pa

(c) Critical crack size can be calculated as; ac = ((KIc^2 x Y)/(σpi))^(1/2)ac = ((23^2 x 0.7)/(28.75 x 10^6 x pi))^(1/2)ac = 1.6 x 10^-3 m

The crack is stable since the size of the crack is less than the critical crack size.

(d) Yes, the condition corresponds to a 'leak before break since the hemispherical crack's growth is slow, and the cylinder could detect it and initiate repairs before the cylinder fails catastrophically.

(e) No, the design will not be 'leak before break since the cheaper aluminum alloy's critical crack size is smaller than the crack's size. Therefore the cylinder will fail catastrophically.

Answer:

Both erg and Joule are units of Energy in the CGS and S.I system respectively.

Joule and erg can also be written as (kg m2/s2) and (g cm2/s2) respectively.

Explanation:

1 Joule = 107 erg ⇒ 107 kg m2/s2.

==>  One erg of energy is the amount of work done when one dyne of force acts through a distance of one centimeter.

==>  One Joule of energy is the amount of work done when one Newton of force (100,000 dynes) acts through a distance of one meter (100 centimeters).

==>  That makes one Joule the same amount of energy as 10 million (10⁷) dynes.

The calculated spring constant is approximately (9.0 s^2 / 4π^2) kg.

The period of vibration of an object attached to a spring is related to the mass of the object and the spring constant. The formula to calculate the period (T) of an oscillating mass-spring system is:

T = 2π√(m/k)

Where:

T = period of vibration

m = mass of the object

k = spring constant

In this case, the period (T) is given as 3.0 seconds, and the mass (m) is 1.0 kg. We can rearrange the formula to solve for the spring constant (k):

T = 2π√(m/k)

(3.0 s) = 2π√(1.0 kg/k)

Now, we can isolate k:

(3.0 s) / (2π) = √(1.0 kg/k)

(3.0 s) / (2π) = √(k/1.0 kg)

Square both sides:

(3.0 s / 2π)^2 = k / 1.0 kg

Simplifying:

(9.0 s^2 / 4π^2) = k / 1.0 kg

Multiplying both sides by 1.0 kg:

k = (9.0 s^2 / 4π^2) kg

Therefore, the calculated spring constant is approximately (9.0 s^2 / 4π^2) kg.

A red light means to stop. If you are turning from a two-way road or onto a two-way road, then you are NOT allowed to reverse your car If you can't do it

Red is typically used to indicate danger or warning, and on traffic lights, it indicates a potential hazard ahead and, as a result, serves as a signal for drivers to stop. If the traffic light turns red while you are already at a junction, you must move swiftly to the opposite side to avoid a potential accident with oncoming traffic.
If the traffic light has turned red as you approach the junction and you are just entering it, you must stop. Unless there is a sign clearly telling you not to turn left at the red light, you may do so. Give way to people and cars coming from other directions when turning.

The time taken is  24 hours and 57 minutes to complete one orbit

We need to find the orbital velocity of the spacecraft OSIRIS-REx.Let it is v. SO,

\(v=\dfrac{2\pi r}{t}\)

Putting all the values,

\(v=\dfrac{2\pi \times 100}{24\ hours\ and\ 57\ minutes}\\\\v=\dfrac{2\pi \times 100}{(86400+3420)}\\\\v=0.00699\ m/s\)

v = 0.0251 km/h

So, the average orbital velocity is 0.0251 km/h.

According to Erikson, a coherent conception of the self, made up of goals, values, and beliefs to which a person is solidly committed is called identity.

Identity, according to Erikson, is a "basic organizing principle that evolves continuously throughout the course of a lifetime."

Identity refers to a person's subjective sense of self, which is comprised of experiences, relationships, beliefs, values, and memories. This makes it easier to maintain a consistent self-image throughout time, even as new aspects of who you are emerging or become stronger.

Identity gives one a sense of self-sameness or continuity both within and in relation to others. Identity, which serves as a framework to distinguish between oneself and social engagement, also contributes to uniqueness. Identity, in addition to the aforementioned, contributes to psychosocial development. Adolescents' physical and mental health is also a component of their identity.

True, heat transfer into a system from the surroundings is considered a positive transfer of energy. This is because the system is gaining energy from its surroundings, causing its internal energy to increase. This can be represented by a positive value for heat transfer (Q) in the equation for the change in internal energy of a system: ΔU = Q - W, where W is the work done by the system. If heat is transferred out of the system and into the surroundings, it would be considered a negative transfer of energy and represented by a negative value for Q.

Answer:

B Raise the object farther off the ground

Answer:

First, we need to remember the second Newton's law:

This says that:

F = m*a

Force equals mass times acceleration.

This means that if we apply a force to an object, the object will accelerate.

This also means that if an object is not moving, or moving with a constant velocity, it will keep doing that until a force is applied.

Now let's answer the 3 cases:

a. The baseball is in space and stationary. What will the ball do? Nothing, it will keep being stationary Why? There is no force applied, or the net force is equal to zero.

b. The ball is in space and someone hits it with a bat. What will the ball do? Will move with constant speed Why? A hit with a bat can be thought as a great force applied for a really short period of time, this means that the speed of the ball will increase a lot, but because the force only last for a really short time, after that the ball will keep moving with constant speed.

c. The ball has a small jet pack attached that is continuously firing. What will the ball do? The ball's speed will keep increasing more and more. Why? Now we have a constant force, this means that we will have a constant acceleration, and as we know, the acceleration is the rate of change of the speed, this will mean that the speed of the ball will keep increasing until the jet pack stops firing, and after that, the ball will keep moving with constant speed.

Answer: the angular acceleration of the wheels is 24.90 rad/s^2.

Explanation:

v = ωr

where v is the linear velocity, ω is the angular velocity, and r is the radius of the wheels.

the linear velocity of the car is 30.0 m/s. The radius of the wheels is 24.1 cm, which is 0.241 m. Therefore:

ω = v / r = 30.0 m/s / 0.241 m = 124.48 rad/s

ωf = ωi + αt

where ωf is the final angular velocity, ωi is the initial angular velocity (which is 0), α is the angular acceleration, and t is the time interval.

Putting in the values, we get:

124.48 rad/s = 0 + α (5.00 s)

α = 24.90 rad/s^2.

Answer:

less than 10 m/s

Explanation:

The 1 kg ball moves after the elastic collision, so you know its speed is > 0.

Due to the law of conservation of momentum, you know the total momentum before the collision must equal the total momentum after the collision.  Some of the momentum from the 4 kg ball transfers to the 1 kg ball (which is at rest) when they collide.  The 4 kg ball slows down after the collision and the lighter ball moves after the collision, but at a speed less than 10 m/s.

Among the given statements about electrical synapses, the incorrect statement is Electrical synapses pass electrical signals between cells with the use of Ach.So option iv is correct.

Electrical synapses do not rely on the use of acetylcholine (Ach) or any other neurotransmitter. Instead, they involve the direct flow of ions between cells through gap junctions. Neurotransmitter-mediated synapses, such as chemical synapses, utilize neurotransmitters like Ach for signal transmission, but electrical synapses bypass the need for neurotransmitter release and binding.

In electrical synapses, the close proximity of the cell membranes allows for the direct transfer of electrical signals (current) from one neuron to another, enabling rapid and synchronized communication. They are fast and exhibit similar properties to the conduction of impulses along single axons. However, electrical synapses are relatively rare in the human nervous system compared to chemical synapses.

The question should be:

Which of the following statements is/are incorrect about the electrical synapse?

(i) At electrical synapses, the membranes of pre and post synaptic neurons are in very close proximity.

(ii) Electrical current can flow directly from one neuron into the other across the synapses.

(iii) Transmission of an impulse across electrical synapses is very similar to impulse conduction along single axon.

(iv) Electrical synapses pass electrical signal between cells with the use of Ach.

(v) Electrical synapses are fast.

stopping distance = 4.52m

stopping distance when speed is doubled = 18.09m

The stopping distance of a sled depends on several factors, including its initial speed, the surface on which it is sliding,

kinetic friction and the resistance provided by the sled's runners or skis.

The stopping distance of the sled can be found using the formula:

stopping distance = (initial speed^2)/(2*coefficient of kinetic friction*acceleration due to gravity)

(a) Plugging in the given values, we get:

stopping distance = (3.50^2)/(2*0.135*9.81) = 4.52 m

Therefore, the sled moves 4.52 meters before it comes to a complete stop.

(b) If the initial speed is doubled to 7.00 m/s, the stopping distance can be calculated as:

stopping distance = (7.00^2)/(2*0.135*9.81) = 18.09 m

Therefore, the stopping distance for the sled would be 18.09 meters if its initial speed is doubled.

This shows that the stopping distance increases significantly as the initial speed increases.

To calculate the height of the table in this scenario, we can use the equations of motion. Let's define the variables first:

Initial velocity (u) = 2.50 m/s (given)

Time taken to reach the floor (t) = 0.391 s (given)

Acceleration due to gravity (g) = 9.8 m/s² (assuming the ball falls freely near the surface of the Earth)

Now, we can use the kinematic equation:

h = u * t + (1/2) * g * t²

Plugging in the given values, we have:

h = (2.50 m/s) * (0.391 s) + (1/2) * (9.8 m/s²) * (0.391 s)²

Simplifying the equation:

h = 0.97875 m + 0.07511 m

h = 1.05386 m

Therefore, the height of the table is approximately 1.05386 meters.
