1.阅读下列材料,并解答问题:
“可燃冰”被视为21世纪的新型绿色能源.科学家估计,全球海洋底部可燃冰分布的范围约4000万平方公里,储量可供人类使用约1000年.我国南海海底存储着丰富的可燃冰资源,已经查明的储量相当于目前陆上石油、天然气资源量总数的三分之一.可燃冰的主要成份是甲烷,1m3可燃冰可转化生成164m3的甲烷气体和0.8m3的水,已知甲烷气体的热值为3.6×107 J/m3.桂林市新开通的301路公交车,使用LNG天然液化气为燃料,这种燃料的主要成份就是甲烷.如果301路公交车满载乘客时总质量是6000kg,1m3可燃冰转化生成的甲烷气体完全燃烧产生的能量,可供公交车满载时以36km/h的速度匀速行驶1640min,行驶中公交车受到的平均阻力为车重的0.05倍,则这段时间内发动机的实际功率和效率各为多大?(g=10N/kg)
3.四棱柱ABCD﹣A1B1C1D1的底面是平行四边形,M是AC与BD的交点.若 {#mathml#}{#/mathml#} = {#mathml#}{#/mathml#} , {#mathml#}{#/mathml#} = {#mathml#}{#/mathml#} , {#mathml#}{#/mathml#} = {#mathml#}{#/mathml#} ,则 {#mathml#}{#/mathml#} 可以表示为( )
4.已知命题p:∀a∈R,且a>0,a+ {#mathml#}{#/mathml#} ≥2,命题q:∃x0∈R,sinx0+cosx0= {#mathml#}{#/mathml#} ,则下列判断正确的是( )
