Answer:

F=0.26N

Explanation:

Assuming that thet act like point charges, the attractive force is given by Coulomb's law:

F=\frac{kq_1q_2}{d^2}

Where k is the Coulomb constant, q_1 and q_2 are the magnitudes of the point charges and d is the distance of separation between them. Thus, we replace the given values and get how strong is the attractive force between them:

F=\frac{8.99*10^{9}\frac{N\cdot m^2}{C^2}(0.7*10^{-6}C)(-0.6*10^{-6}C)}{(12*10^{-2}m)^2}\\F=0.26N

A heat engine operates between a hot reservoir with a temperature of 400 K and a cold reservoir with a temperature of 300 K. The
natali 33 [55]

Answer:

Explanation:

Given

Temperature of Hot reservoir T_1=400 K

Temperature of Cold reservoir T_2=300 K

Heat reservoir Q=500 J

Work done W=150 J

heat Exhaust Q_{rejection }=350 J

Q=W+Q_{rejected}

500=150+350

L.H.S=R.H.S

thus it follows first law

\eta _{carnot}=1-\frac{T_L}{T_H}

\eta _{carnot}=1-\frac{300}{400}

\eta _{carnot}=0.25

Cycle Efficiency

\eta =\frac{W}{Q}=\frac{150}{500}=0.3

Carnot efficiency is less than cycle thus it violates second law
