Question
"Given Vo-36V, R-2500 , and C-1600 calculate the voltage 8 seconds after the switch is closed 3) According to special relativity, a rod of length L moving at velocity v will shorten by an amount , given by: where c is the speed of light (about 300 × 106 m/s). Calculate how much a rod 2 m long will contract when traveling at 5,000 m/s 4) Using the zeros, ones, and eye commands create the following arrays by typing one command: 0 1110 (c) 01110 00001 (a) 1011 0100 Solve the following system of five linear equations 2.5a-b+3c+1.5d -2e 57.1 3a +4b-2c+2.5d-e-27.6 4a+36+c-6d+ 2e -81.2 2a +3b+ c-2.5d+4e-222 a+2b+5c-3d+4e-12.2 MacBook Air 11 3 4Explanation / Answer
Solution 4:
Undestand the basic meaning of ones,zeros and eye
zeros(n , m) returns an n-by-m matrix of zero
ones(n , m) returns an n-by-m matrix of one
eye(n , m) returns an n-by-m identity matrix with ones on the main diagonal and zeros elsewhere.
(a) A = [eye(2,2) ones(2,2) zeros(2,1)]
(b) A = [ones(2,4) ; eye (2,2) zeros (2,2)]
(c) A = [zeros(2,1) ones (2,3) zeros(2,1) ; zeros (2,4) ones (2,1)]
