把 \(1kg\)，\(20^\circ C\) 的水放到温度恒为 \(500^\circ C\) 的炉子上加热，最后水温达到 \(100^\circ C\)。在这个过程中，水和炉子的熵变分别为 [已知水的比热为\(4.18 \times 10^3 J/(kg \cdot {^\circ C)}\)] A: \(1.01 \times 10^3 J/K\)，\(–0.43 \times 10^3 J/K\)。 B: \(1.01 \times 10^3 J/K\)，\(–0.90 \times 10^3 J/K\)。 C: \(0.90 \times 10^3 J/K\)，\(–0.43 \times 10^3 J/K\)。 D: \(0.90 \times 10^3 J/K\)，\(–0.90 \times 10^3 J/K\)。

In Life and Times of Michael K, K’s birth defect is related to one of the themes of the novel.

How many times will the loop body be executed? int k=0; while(k=1)k++;

In Life and Times of Michael K, pumpkin seeds represent hope and life.

At the beginning of Life and Times of Michael K,,K is still hopeful of his life and realizing his mother’s dream.

以下程序的输出结果是______。 #define TIMES(X) X*X main() int a=16,k=2,m=1; a/=TIMES (k+m)/TIMES(k+m); printf("d\n", A: ; B: &n

If k is integer, how many times will the following "while" loop be executed?k = 50 while k >; 1: print(k) k = k // 2 A: 3 B: 4 C: 5 D: 6

某同学的投篮命中率为\(0.3\)。该同学投篮10次，若投中的次数用\(X\)表示，则\(X\)的分布律为：\(P\{X=k\}=C_{10}^k\times 0.3^k\times 0.7^{10-k},k=0,1,2,\ldots,10.\)

If k is integer, how many times will the following "while" loop be executed?k = 50 while k > 1: print(k) k = k // 2 A: 3 B: 4 C: 5 D: 6

设\( A \)为\( m \times n \)矩阵，\( B \)为\( n \times k \)矩阵，若\( AB = O \)，则\( R(A) + R(B) \le n \).
