自然科學 大學 2年以上以前 (普通物理)想請問這題該如何解🙏 10. A particle moves from the origin to the point x = 3 m, y=6 m along the curve y = ax_ - bx, where a = 2 m' and b = 4. It's subject to a force cxyî + dị, , where c = 10 N/m² and d = 15 N. Calculate the work done by the force. c - - - 尚未解決 回答數: 2
自然科學 大學 2年以上以前 求解 為什麼動量不需要代速度值?🤔 6.51 Using Heisenberg's uncertainty principle, calculate the uncer- tainty in the position of (a) a 1.50-mg mosquito moving at a speed of 1.40 m/s if the speed is known to within £0.01 m/s; (b) a proton moving at a speed of (5.00 + 0.01) X 104 m/s. (The mass of a proton is given in the table of fundamental constants in the inside cover of the text.) (a) Ax >= h bar /24p = 6.626*10-34/(1.5*10-6*0.01)/41 = 4/41*10-27 m (b) Ax >= h bar/24p = 6.626*10-34/(1.67*10-27*0.01)/41 = 3/41*10-10 m * 尚未解決 回答數: 1
