Answer:

0.000001 kg

Explanation:

because 1 kg equal 1,000,000 milligrams

we take $\frac{1}{1,000,000}$ which equals 0.000001 kg

Hydraulic brakes use Pascal’s principle. The driver exerts a force of 100 N on the brake pedal. This force is increased by the s

Rus_ich [418]

Answer:

Explanation:

Pascal's law states that when there is an increase in pressure at any point in a confined fluid, the pressure is equally distributed at every other point in the container.

The formulas that relate to this are given below:

P1 = P2 (since the pressures are equal throughout).

P2 is the pressure transmitted in the hydraulic system

N.B : P= Force/ Area

Therefore we have

F1/A1 = P2

F1= the force exerted by the driver = 100N

P2= 100/A1 N/m² or 100/A1 pa or 100/(101325× A1) atm

1. A heat engine operates between two reservoirs at T2 = 600 K and T1 = 350 K. It takes in 1.00 x 103 J of energy from the highe

Alex73 [517]

Answer:

$\Delta S_u=2.1429\ J.K^{-1}$

$W_c=416.67\ J$

Explanation:

Given:

temperature of source reservoir, $T_H=600\ K$

temperature of sink reservoir, $T_L=350\ K$

energy absorbed from the source, $Q_{in}=1000\ J$

work done, $W=250\ J$

Now change in entropy of the surrounding:

$\Delta S_u=\frac{dQ_L}{T_L}$

Since heat engine is a device that absorbs heat from a high temperature reservoir and does some work giving out heat in the universe as the byproduct.

$\Delta S_u=\frac{Q_H-W}{T_L}$
