Two or more velocities add by vector addition
Answer:
1.69515 seconds
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
The distance between the traffic and the car after braking is 120-64.06 = 55.94 m
Time = Distance / Speed
The reaction time cannot be more than 1.69515 seconds
Photons are particles of electromagnetic radiation.
Answer:
change in internal energy 3.62*10^5 J kg^{-1}
change in enthalapy 5.07*10^5 J kg^{-1}
change in entropy 382.79 J kg^{-1} K^{-1}
Explanation:
adiabatic constant
specific heat is given as
gas constant =287 J⋅kg−1⋅K−1
specific heat at constant volume
change in internal energy
change in enthalapy
change in entropy
