Q1 Measuring gravity by dropping a ball in a vacuum n an experiment, a ball was dropped through a vertial distnace from rest. The vertical distance tranversed and the corresponding time interva measured at these distances were 3.24, 2.68, 2.35, 1.87, 2.57,2.77 meters, with the corresponding time intervals 0.81, 0.74, 0.69, 0.61, 0.72, 0.75 seconds. The time intervals are measured with an error bar of 0.1 second. Determine the best-fit value of g by fitting the data points against the formula h = gt2 by taking into accont the error in time the time interval. Be reminded that the argument 'sigma' and absolut_sigma=True' in scipy.optimize.curve_fit() are associated with the error bar in h (not At). Hint : You have to calculate Ah for each pair of hị, t¡. Hint : Vour result should be the same (or almost the same) as that obtained using t - 2h

In c++ please help me answer this question I will give you a good rating :) implement the three versions of the addupto20() function: iterative, recursive, and divide-and-conquer approach test these functions with a few inputs from your main() Iterative solution * check if there exsits two numbers from vector data that add up to 20 e.g., if data=[2,5,3,15], the function returns true, as data [0] +data [3]==20 e.g., if data=[3,4,0,8], the function return false precondition: vector data has been initialized postcondition: if there are two numbers from list add up to 20, return true; otherwise, return false */ bool AddupTo20 (const vector‹int> & data){ } Come up with a recursive solution to the problem, following the hints given below: * check if there exsits two numbers from vector data[first...right] add up to 20 e.g., if data=[2,5,3,15], first=0, last=3, the function returns true, as data [0] +data [3]==20 e.g., if data=[2,5,3,15], first=2, last=3, the function returns…

Consider the following context-free grammar for statements: 1) E > E+T 2) E →T 3) T > I*F 4) T →F 5) F → (E) 6) F → id which can be analyzed with the LR Parsing Table given as following. Action Goto id + * () $ ETF State s5 s4 |12 3 1 s6 асс 2 r2 s7 r2 r2 3 r4 r4 r4 r4 4 $5 $4 8 2 3 5 r6 r6 r6 r6 6. s5 $4 9 3 7 s5 $4 10 s6 s11 9 rl s7 rl rl 10 r3 r3 r3 r3 11 r5 r5 r5 r5 Show a complete parse, including the parse stack contents, input string, and action for the string id*(id + id), using the grammar and parse table given. 8.

Data Structures and Algorithms in C/C++ a) Implement the addLargeNumbers function with the following prototype: void addLargeNumbers(const char *pNum1, const char *pNum2); This function should output the result of adding the two numbers passed in as strings. Here is an example call to this function with the expected output: /* Sample call to addLargeNumbers */ addLargeNumbers("592", "3784"); /* Expected output */ 4376 b)  Implement a test program that demonstrates adding at least three pairs of large numbers (numbers larger than can be represented by a long). c) (1 point) Make sure your source code is well-commented, consistently formatted, uses no magic numbers/values, follows programming best-practices, and is ANSI-compliant.
