Awnser: 600 meters per hour
Step by step explication:
Covert 14 minutes to a fraction of an hour by dividing it by 60, because 60 is how many minutes in an hour and we need to convert it to a decimals. Then divide the distance, 150 meters by the fraction of an hour, .25 to abstain the velocity (speed) of 600 meters per hour.

Answer:

The value of $X = 1000 \ N$ and $Y = 1400 \ N$

Explanation:

Considering the diagram,

Taking moment about the pivot , we have

$X * 1 = 400 * 2.5$

=> $X = 1000 \ N$

Generally given that the bar is at equilibrium then the upward forces is equal to the down ward force

So

$Y = X + 400$

=> $Y = 1000 + 400$

=> $Y = 1400 \ N$

Answer:32.83

Explanation:

Given

$T_H=91^{\circ}\approx 364 K$

$T_L=17^{\circ}\approx 290 K$

Q=46830 J

Total Entropy change of system

$\Delta s=-\frac{Q}{T_H}+\frac{Q}{T_L}$

$\Delta s=-\frac{46830}{364}+\frac{46830}{290}$

$\Delta s=-128.65 +161.48=32.83 J/K$
