Answer:
leggings
Explanation:
they allow the metal or sparks to not hurt you can the leggings can be easily and quickly removed.
Answer:
Impossible.
Explanation:
The ideal Coefficient of Performance is:
The real Coefficient of Performance is:
Which leads to an absurds, since the real Coefficient of Performance must be equal to or lesser than ideal Coefficient of Performance. Then, the cycle is impossible, since it violates the Second Law of Thermodynamics.
Answer:
74,4 litros
Explanation:
Dado que
W = nRT ln (Vf / Vi)
W = 3000J
R = 8,314 JK-1mol-1
T = 58 + 273 = 331 K
Vf = desconocido
Vi = 25 L
W / nRT = ln (Vf / Vi)
W / nRT = 2.303 log (Vf / Vi)
W / nRT * 1 / 2.303 = log (Vf / Vi)
Vf / Vi = Antilog (W / nRT * 1 / 2.303)
Vf = Antilog (W / nRT * 1 / 2.303) * Vi
Vf = Antilog (3000/1 * 8,314 * 331 * 1 / 2,303) * 25
Vf = 74,4 litros

Answer:
5320.6 Pascal
Explanation:
Manometer is a pressure measuring device use to measure gas pressure .
Pressure difference in Manometer is a function of density,gravity and the height difference of the liquid.
Pressure difference = density x acceleration due to gravity x difference in height of liquid
Density of liquid = specific gravity of object x density of water.
Density of water = 997 kg/m^3
Specific gravity of liquid = 1.7
Density of liquid = 997 x 1.7 =1694.9kg/m^3
g= 9.81 m/s^2
h =320mm = 0.320m
Pressure difference = 1694.9 x 9.81 x 0.320 = 5320.6 Pascal
