2016年12月20日，中国自主建造的第一艘极地科学考察破冰船(H520)正式开工建造.设计空载排水量为8000t，满载排水量为14000t，它能在覆盖有0.2m厚积雪的1.5m厚冰层上以3.6km/h~7.2km/h的速度连续破冰.(g取10N/kg)

(1)破冰船“H520”用厚钢板做船底，主要是因为钢板具有____(选填序号).①良好的导电性;②较高的硬度;③较高的熔点;④良好的导热性.

(2)假设在1.5m厚的冰层海域以7.2km/h的速度匀速破冰时所受的阻力为2×107N，则根据设计要求破冰船“H520”推进功率多大?

(3)破冰船“H520”可采用“重力破冰法”破冰，“重力破冰法”是指在接触冰面前，船全速航行，船体大部分冲上冰面，就可以把冰压碎，若此时船的排水体积变为原来的七分之二，假设当时破冰船“H520”满载，船与冰层接触面积为5m2，则该破冰船对冰层的压强是多少?(海水的密度取1.0×103

kg/m3)
