A stream of warm water is produced in a steady-flow mixing process by combining 1.0 kg/s of cool water at 25 °C with 0.8 kg/s of

Tamiku [17]

Explanation:

The given data is as follows.

$m_{1}$ = 0.8 kg/s = 800 g, $C_{1} = 4.18 J/g^{o}C$

$m_{2}$ = 1 kg = 1000 g, $T_{1}$ = (75 - T),

$T_{2}$ = T - 25

Now, according to the law of conservation of energy,

$m_{1}C_{1}T_{1} = m_{2}C_{2}T_{2} + mL$

$800 \times 4.18 \times (75 - T) = 1000 \times 4.18 \times (T - 25)$ + 30000

250.8 - 3.34T = 4.18T - 104.5 + 30

T = $\frac{325.3}{7.52}$

= $43.23^{o}C$

Thus, we can conclude that temperature of the warm water stream is $43.23^{o}C$ .

b) When the ball is near its maximum height it experiences a brief gust of wind that reduces its horizontal velocity by 2.50 m/s

fomenos

Answer:

The horizontal distance is 0.64 m.

Explanation:

Initial velocity, u =2.5m/s

The maximum horizontal distance is

$R = \frac{u^2}{2g}\\\\R = \frac{2.5\times 2.5}{9.8}\\\\R = 0.64 m$
