To measure a base lone, a steel stape 30m lang, Standardised at 15°C with a pull of 80N was used. find the correction per tape length, if the tempreture at the time of measurements is 25°c and the pull exerted is 150N. Take young's modulus E= 2X10^5 N/mm2 and coefficient of thermal expansion 211.2x10^6c°Cross-sectional area of tape is 8mm2
Answers
The correction of thermal expansion per tape length, if the temperature at the time of measurements is 25°c and the pull exerted is 150N is 4.67 ×10 ⁻³m.
Thermal expansion is the tendency of remembering to change in form, volume, and region in response to an alternate in temperature. Temperature is a monotonic characteristic of the common molecular kinetic power of a substance.
Given,
Length of steel tape = 30m
Temperature at standardization = 15°C
The temperature at the time of measurement = 25°C
Standardized pull (Po) = 80N
Pull exerted (Pm) = 150N
Young modulus of elasticity = E = E= 2X10^5 N/mm2
Coefficient of thermal expansion = 211.2x10^6c°
Cross-sectional area of tape = 8 mm²
For temperature correction Cm = (Tm - T₀)αL₀
Putting α = ( 25 - 15 ) × 11.2 × 10⁻⁶ × 30
Cm = 3.36 × 10⁻³ m
For full correction ;
C pull = (Pm - Po ) × Lo
Putting value'
C pull = (150 - 80) × 30 × 1000 /8 ×2 × 10⁵
C pull = 1.31 × 10 ⁻³
Total correction = 3.36 × 10⁻³ m + 1.31 × 10 ⁻³
Total correction = 4.67 ×10 ⁻³

Answers
The following best explains how a wheat farmer in the Northern Plains region of the United States is able to maximize profits: Grain farming is an extensive farming practice that can maximize profits in part by lower land costs, lower transportation costs, and imperishability of the product. Therefore the correct option is option B.
Grain farming is the cultivation of grain crops such as corn, wheat, oats, and barley. In the Northern Plains region of the United States, wheat is the primary grain crop. Wheat is grown for both human and animal consumption.
Grain farming in the Northern Plains region of the United States requires extensive land areas to produce a large volume of wheat, making it an extensive farming practice. Because wheat is an imperishable product, the cost of transportation to distant markets is lower.
As a result, farmers can maximize their profits by producing large volumes of wheat in the Northern Plains and selling it in urban areas, where demand is higher. Lower land costs also contribute to the profitability of grain farming in the Northern Plains region.

Part 3: GRLevel3 and Dual Pol
For this part, you will follow the instructions below. The data files for GRLevel3 can be found in the same area you fount this assignment.
Our goal with this case study involving Pulse Storms is to learn how to identify a ZDR column (aka an updraft) using both standard and Dual-Pol products.
First, we want to do our situational awareness to best understand what is going on. Therefore, on the next page are the 500 mb map, as well as the sounding for Minneapolis, MN.
Next, we need to load the data. In the same Module as you found this file, you should see a file called “Quarter3HWdata.zip”. Please download this file and unzip it. There should be 19 files in there that are ready to be used in GRLevel3. This will load data from the KARX radar in La Crosse, WI.
Now let‘s load the data that you’ve just unzipped into GRLevel3. Let the data loop through a few times to get an idea of the event. This loop should be a BR0.5, which is Base Reflectivity at 0.5°. Next, loop the data through a few times for each of the following products: VIL, CR, Echo Tops, ZDR, CC, and HCA.
Next, let‘s go over how to identify an updraft using Dual-Pol products. This can be accomplished by using BR, ZDR, and CC together. I’d suggest that before you advance any further you give a quick (re-)read of the “Updraft (ZDR Column)” section on page 43 in the Dual-Pol Students Guide.
To start with, let’s use the Melting Layer tool to estimate the freezing level. You can turn this on by clicking the button directly beneath the HCA tab.
In doing this, a series of 4 rings should appear on the display. Further, these rings should be centered on the radar site.
If you need a refresher in how to interpret the Melting Layer, then take another look at Figures 5-2 and 5-3 in the Dual-Pol Students Guide.
Next, we would like to look at 4 panels at once! To do this, first go to the Windows tab, then select Four Panels. The 4 panels you need to display are (clockwise from top left) BR1.5, ZDR1.5, CC1.5, and HCA1.5. In order to get the panels set up properly, first select the panel you want to change by clicking on this panel. Next, simply select the product and angle you want from the tabs above. This should do it! It should look something like this:
In the lower left corner of each panel is text indicating the product type and tilt.
Next, zoom in on the area where you believe the most convection is present. Once you’ve done this, loop the images a few times to get a feel for things. In order to identify the updraft (ZDR column), you want to find an area if greater than 25 dBZ on the BR1.5, greater than 1.5 dBZ on the ZDR1.5, and less than 97% on CC that is outside of the second bold white circle.
HINT: An easy way to compare the same location(s) on all 4 panels if to drop a marker on the radar echo where you are studying. You can do this by giving a right click, then selecting “Place Marker Here”).
With all this information, you should be able to answer the following questions:
1. Where is the most intense convection?
2. Once you have identified this area of greatest convection, zoom in on this area and take a screen capture of the radar (File, Save Image, Entire Window). Please turn in the image with your homework.
3. What is the depth of the melting layer?
Answers
It should be noted that to identify the area of most intense convection, you will need to loop through the various products mentioned in the instructions, including Base Reflectivity at 0.5° (BR0.5), VIL, CR, Echo Tops, ZDR, CC, and HCA.
How to explain the informationOnce you have a good understanding of the event, you can use the Melting Layer tool to estimate the freezing level and identify the area of greatest convection.
Once you have identified the area of greatest convection, zoom in on this area and take a screen capture of the radar by going to File, Save Image, and selecting Entire Window. Please turn in the image with your homework.
Also, to determine the depth of the melting layer, you can refer to the Melting Layer tool and the accompanying figures in the Dual-Pol Students Guide, which explain how to interpret the rings that appear on the display when the tool is turned on. The depth of the melting layer can be estimated by measuring the distance between the rings.
