how to add breadth first traversal in binary tree python
Answers
```
class Node:
def __init__(self, data):
self.left = None
self.right = None
self.data = data
def breadth_first_traversal(root):
if not root:
return
queue = []
queue.append(root)
while queue:
current = queue.pop(0)
print(current.data)
if current.left:
queue.append(current.left)
if current.right:
queue.append(current.right)
```
In this code, `Node` represents a single node in the binary tree, with `left` and `right` pointers to its children and a `data` field to hold the value of the node.
The `breadth_first_traversal` function takes the root node of the binary tree as input, and uses a queue to keep track of the nodes we need to visit next. We add the root node to the queue, and then enter a loop where we `pop` the first item in the queue and visit its data.
We then add the left and right children of the current node to the queue, if they exist. We continue this loop until we have visited all nodes in the tree.
To add breadth first traversal in a binary tree using Python, you can implement a queue-based approach. First, you start with the root node and add it to the queue.
Then, while the queue is not empty, you remove the first node in the queue, print its value, and add its children to the queue (if they exist) from left to right. This process continues until the queue is empty.
Here is a sample code snippet to implement breadth first traversal in a binary tree using Python:
```
class Node:
def __init__(self, value):
self.left = None
self.right = None
self.value = value
def breadth_first_traversal(root):
if root is None:
return
queue = []
queue.append(root)
while queue:
curr_node = queue.pop(0)
print(curr_node.value)
if curr_node.left is not None:
queue.append(curr_node.left)
if curr_node.right is not None:
queue.append(curr_node.right)
# Example binary tree
# 1
# / \
# 2 3
# / \ / \
# 4 5 6 7
root = Node(1)
root.left = Node(2)
root.right = Node(3)
root.left.left = Node(4)
root.left.right = Node(5)
root.right.left = Node(6)
root.right.right = Node(7)
breadth_first_traversal(root)
```
This code will output the following result:
```
1
2
3
4
5
6
7
```
Here, the breadth first traversal visits each node at each level of the binary tree from left to right.

Static Friction and Kinetic Friction
Recall from the previous chapter that friction is a force that opposes motion, and is around us all the time. Friction allows us to move, which you have discovered if you have ever tried to walk on ice.
There are different types of friction—kinetic and static. Kinetic friction acts on an object in motion, while static friction acts on an object or system at rest. The maximum static friction is usually greater than the kinetic friction between the objects.
Imagine, for example, trying to slide a heavy crate across a concrete floor. You may push harder and harder on the crate and not move it at all. This means that the static friction responds to what you do—it increases to be equal to and in the opposite direction of your push. But if you finally push hard enough, the crate seems to slip suddenly and starts to move. Once in motion, it is easier to keep it in motion than it was to get it started because the kinetic friction force is less than the static friction force. If you were to add mass to the crate, (for example, by placing a box on top of it) you would need to push even harder to get it started and also to keep it moving. If, on the other hand, you oiled the concrete you would find it easier to get the crate started and keep it going.
Figure 5.33 shows how friction occurs at the interface between two objects. Magnifying these surfaces shows that they are rough on the microscopic level. So when you push to get an object moving (in this case, a crate), you must raise the object until it can skip along with just the tips of the surface hitting, break off the points, or do both. The harder the surfaces are pushed together (such as if another box is placed on the crate), the more force is needed to move them.

the fluid control function of a fluid power system controls system pressure and fluid flow rate and
Answers
The fluid control function of a fluid power system controls system pressure and fluid flow rate, and it also regulates fluid direction and distribution.
Fluid Direction and Distribution: In addition to controlling pressure and flow rate, the fluid control function governs the direction and distribution of fluid within the system. Directional control valves, such as solenoid valves or manual valves, are used to determine the pathways and routes through which fluid flows. By actuating these valves, the fluid control function directs the fluid to specific actuators, cylinders, or other components, enabling precise control over the system's operation.
Fluid control also involves managing the distribution of fluid among various branches or circuits within a fluid power system. This is achieved through the use of manifold systems, which consist of interconnected valves and passages that control the flow distribution to different parts of the system. By selectively opening or closing valves within the manifold, the fluid control function ensures that the fluid is appropriately distributed to the desired areas of the system.
The fluid control function in a fluid power system encompasses the regulation of system pressure, fluid flow rate, fluid direction, and fluid distribution. By effectively managing these aspects, the fluid control function enables precise control, efficient operation, and reliable performance of the fluid power system.

figure below shows the grain boundaries of low-carbon steel under a microscope with 400x magnification. what is the astm grain-size number? i. 8 ii. 7 iii. 9 iv. 10
Answers
10 is the astm grain-size number of low-carbon steel.
What is low-carbon steel?
Low-carbon steel, often known as mild steel, is now the most prevalent type of steel due to its low cost. At the same time, it has material properties that are suitable for a wide range of applications. Low-carbon steel has a carbon content of 0.05-0.25%, making it malleable and ductile. Mild steel has a low tensile strength but is inexpensive and simple to produce; surface hardness can be enhanced by carburizing.
Counting of no of grains are done in such a way:
Count whole grains as 1.
Count grains which are more than half, calculate then as 1/2.
So, Total no of grains in given picture at 400X is
=(13 whole)+(18 half)
=(13×1)+(18×1/2)
= 22
∴ Avg no of grains per square inch at 100X magnification
N= (400/100)²×22
⇒ N= 352
Now, N= 2ⁿ⁻¹, here n= ASTM grain size no
⇒ N=(n-1)/n²
⇒(352)/(2) = n-1
⇒ n = 9.46 ≈ 10
So, option (iv) is right.

Rapidly overtaking a bicycle is dangerous. Also, there are some vehicle drivers who drive into the lanes that are meant for cyclists. This isn't appropriate.
Drivers should ensure that they are not close to the cyclists when driving as there should be a space of at least 3 feet between the bicycle and the vehicle.
Furthermore, when there is a narrow traffic lane, the vehicle drivers should ensure that there's a clear traffic in the opposite lane before they change their lanes.
Lastly, both the cyclists and the vehicle drivers should not overspeed and drive safely.

consider the statement: we should always have a bag of gypsum in the field in case the cement is reacting too fast. is it correct?
Answers
The statement "We should always have a bag of gypsum in the field in case the cement is reacting too fast" is correct. Gypsum is used in construction projects to slow down the setting time of cement.
Why do we use gypsum in construction?Gypsum is used in the construction industry because it has a special property that allows it to slow down the setting time of cement. This can be useful in many different situations. For example, if the weather is particularly hot or dry, cement can sometimes set too fast. This can be problematic because it may not give the workers enough time to complete the job before the cement sets. By adding gypsum to the cement mixture, the workers can extend the working time, and the cement will not set too fast.
Cement is a type of building material that is used to create foundations, walls, and other structures. It is made by mixing sand, gravel, and other materials with water to create a paste. This paste is then allowed to dry and harden into a solid mass. However, the drying and hardening process can sometimes happen too quickly, which can be a problem for workers who need more time to complete their work. Adding gypsum to the cement mixture can slow down this process and make it easier for workers to complete their jobs on time.

In the CGS system, the unit of charge is the charging unit (ESU). Also known as "Statistical Pendant" (StatC). In the CGS system, the load unit is the electromagnetic unit (E.M.E.).
The e.s.u. of charge, also known as franklin or statcoulomb, is the charge such that two similar q=1statC charges at a space of 1cm from each other exert an electrostatic force of 1dyn on each other.
The e.m.u. of current, also called the biot or abampere, is the current such that two infinitely-long straight, parallel conductors carrying 1abA of current and separated by 1cm exert a magnetostatic force of 2dyn on each other.
The relations between these units are such that
\(\frac{1 statC}{1 abA * 1s} = \frac{1 statC}{1abC} = \frac{1}{C} = \frac{1 statA}{1abA} = \frac{\frac{1 statC}{s} } {1 abA}\)
where c is the speed of light.
The ESU and EMU systems of electromagnetic units are different and they should generally be considered separate and independent (if relatively similar), and they do not coincide with the gaussian set of electromagnetic units.
For example, since the electrical displacement vector D is defined as \(E + 4\pi P\) in the ESU system and \(\frac{1}{c^{2} } E + 4\pi P\) the EMU system, it is not possible to exchange the formulas of one system for another without using a formula dictionary like the one at Jackson's end.

A yeast culture weighing 2 grams is removed from a refrigerator unit and is expected to grow at the rate of W'(t)=0.3e02 grams per hour at a higher controlled temperature. How much will the weight of the culture increase during the first 8 hours of growth? How much will the weight of the culture increase from the end of the 8th hour to the end of the 16th hour of growth?
The weight increase during the first 8 hours is approximately grams. (Type an integer or decimal rounded to three decimal places as needed.)
Answers
The weight of the culture will increase approximately 0.859 grams during the first 8 hours of growth.
To find the weight increase during the first 8 hours of growth, we can integrate the rate of growth function W'(t) over the interval [0, 8].
Given that W'(t) = \(0.3e^0.2\)grams per hour, the weight increase during the first 8 hours is:
\(∫[0, 8] W'(t) dt = ∫[0, 8] 0.3e^0.2 dt\)
Integrating this function, we have:
\(∫[0, 8] 0.3e^0.2 dt = 0.3∫[0, 8] e^0.2 dt\)
Integrating \(e^0.2\) with respect to t gives:
\(0.3 * (1/0.2) * e^0.2 ∣[0, 8] = 0.3 * (5 * e^0.2 - 1)\) ≈ 0.859 grams
Therefore, the weight of the culture will increase approximately 0.859 grams during the first 8 hours of growth.
