When horizontal force is applied on block then as per Newton's II law we will have
so here mass will be
now on same block F = 5 N is applied on surface of Moon
so on surface on moon we will have
so above is acceleration on surface of moon
Answer:
Given:
Th = 270 °C = 270+273 = 543 K, hot temperature
Tc = 210 °C = 210+273 = 363 K, cold temperature
According to the Carnot theorem, the maximum efficiency achievable by a heat engine between a hot and cold temperature is
η = 1 - Tc/Th
= 1 - 363/543
= 0.668 = 11.047 (approx)
Answer: 11.0% (nearest integer)
