An object is moving with constant speed in a circular path. The object's centripetal acceleration remains constant in A)
magnitude, only

B)
direction, only

C)
both magnitude and direction

D)
neither magnitude nor direction

Ais the answer hope this

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.
