A2.0 kg block is placed against an ideal spring with spring constant 800 n/m and initially compressed 0.40 m. the spring and block lie on a frictionless 30 degree incline. the system is then released from rest and the block slides up the incline. how far along the inclined surface (distance d in sketch) does the mass slide before coming to rest (reaching its maximum height)?

A., d., and f i think

Good moring let me you on this question the answer the electric force  have a good day ; )

If the heat engine is a perfect carnot cycle engine, thenefficiency = (t2-t1)/t2   where t1=temperature of cold reservoir ( ° k) = 135            t2=temperature of hot reservoir ( ° k)   = 325thereforeefficiency = (t2-t1)/t2 = (325-135)/325 = 0.5846 = 58%  note: this is the theoretical maximum efficiency of a perfect heat engine.   real-life engines do not achieve this value.
