- As we learned in the lecture, computer software uses decimal degrees (DD), as they are much easier to handle in complex algorithms for various mapping applications. Your task is to convert Lat-Long from DMS to DD and vice versa. Remember: when using DD, the cardinal direction are replaced by positive and negative numbers . The "+" sign is omitted (it is implied) and only the minus sign "--" is mandatory . (See lecture) Washington Monument in DC has the following coordinates, in DMS: LAT: 38 deg 53 min 22 sec North ; LONG: 77 deg 02 min 19 sec West. Use an online converter (such as https://www.latlong.net/degrees-minutes-seconds-to-decimal-degreesLinks to an external site.) and find the coordinates in decimal degrees. Choose the correct coordinates in DD for the Washington Monument: 38.88944444 , 77.03861111 38.88944444 , --77.03861111 --38.88944444 , 77.03861111 --38.88944444 , --77.03861111arrow_forwardI need to know about the ground track coverage of a satellite. The following MATLAB code plots the orbit of a satellite in lat vs long. It also plots a building which we assume is the ground station. Does the building have coverage of the satellite? The plot shows the building is outside of the orbit of the satellite. If it does have coverage, how much time per day does it have coverage. % Initial conditionsomega_earth = rad2deg(7.2921151467e-5); % deg/sa = 3096.7363; % kmecc = 0.74;inc = 63.4349; % degreesraan = -86.915798; % degreesargp = 270; % degreesf = linspace(0, 360, 100); % degreest = 100; % number of pointscone_angle = 10; % degrees % Building coordinatesbuilding_lat = 40.43094; % degreesbuilding_long = -86.915798; % degrees position = (lla2eci([building_lat building_long 0],[2024 01 24 12 20 0]))/1e3 % Calculate time vector over one orbital periodorbital_period = 360 / omega_earth;time_vector = linspace(0, orbital_period, t); % Preallocate arrays for orbital elementslong =…arrow_forwardUsing the MATLAB editor, make a script m-file for the following: The velocity of an object dropped vertically from a height h0 as it falls is given by: And that h0 = 42 meters and g = 9.81 m/sec2 For values of h from 42 to 0 meters in increments of 0.5 metersMake variables h0 and g and assign valuesFind the values of v in m/sDisplay the results on a x-y log-log plot With h the independent variable plotted on the x axisAnd v the dependent variable plotted on the y axisInclude units within the labelsarrow_forward
- Write a function in Python to perform a two sample t-test. The t-test should be unpaired and you may assume that the samples have equal variance. The function should have: specify a choice of alternative hypotheses by giving arguments “two-sided”, “less”, or “greater”. If no such alternative is given, then the default should be “two-sided” specify a parameter mu indicating the true difference in means under the null hypothesis. If unspecified, the default should be mu=0. result should be a dict with the labeled values of the t-statistic and the p-value function should be my_ttest(x,y,mu,alternative), where x and y are the two samples being compared. use the function scipy.stats.t.cdf to calculate p-values generate random samples for testing using npr.normalarrow_forwardWrite a Jupyter code for the following.arrow_forwardImplement the Linear regression for multiple variables. code in python and execute and take screen shot of code and output use PYTHON IDLE GIVE EXPLANATION TO SAMPLE CODE EXECUTED. please use 201916778 as a file name thank you in advancearrow_forward
