Answer:
the magnitude of Vpg = 493.711 km/h
Explanation:
given data
speed Vpg = 560 km/h
speed Vwg = 80 km/h
solution
we get here magnitude of the plane velocity w.r.t. ground is
we know that the Vpg = Vpw + Vwg .....................1
writing the component of the velocity that is
Vpw = (0 km/h î - 560 km/h j )
Vwg = (80 cos 45 km/h î + 80 sin 45 km/h j)
adding these
Vpg = (0+80 cos 45 km/h ) î + ( -560 + 80 sin 45 km/h j)i
Vpg = (42.025 ) î (-491.92 km/h)j
now we take magnitude
the magnitude of Vpg =
the magnitude of Vpg = 493.711 km/h
Answer : The correct option is, (B) 279.2 Kpa
Solution : Given,
Initial pressure of gas = 475 Kpa
Initial volume of gas =
Final volume of gas =
Initial temperature of gas = 290 K
Final temperature of gas = 277 K
Using ideal gas equation :
Formula used :
where,
= initial pressure of gas
= final pressure of gas
= initial volume of gas
= final volume of gas
= initial temperature of gas
= final temperature of gas
Now put all the given values in the above formula, we get the final pressure of the gas.
Therefore, the absolute pressure of the gas after expansion is, 279.2 Kpa
