- 【单选题】底面半径为 R高为R的圆锥体积为V 1 ,半径为 R的半球体积是V 2 ,底面半径为 R高为R的圆柱体积为V 3 ,则有() A. V 1 :V 2 :V 3 =1:4:9 B. V 1 :V 2 :V 3 =1:2:3 C. V 1 :V 2 :V 3 =1:3:5 D. A.V 2 2 =V 1 V 3
- php $v=1; for($i=1;$i<=3;$i++){ while($v<5){ $v++; if($v==4){ break 2; } echo $v; } }
- 如图所示电路，已知ε1=5 V，ε2=3 V，R内1=R内2=1 Ω，R1=R2=R3=2 Ω，则Uab=[img=218x121]17e0aaba219d507.jpg[/img] A: 5 V B: 2 V C: -1 V D: 1 V E: -2 V
