A system undergoes a two-step process. In the first step, the internal energy of the system increases by 222 J when 150 J of wor k is done on the system. In the second step, the internal energy of the system increases by 123 J when 195 J of work is done on the system. For the overall process, find the heat.
1 answer:
Answer:0 J
Explanation:
Given
For first step
change in internal Energy of the system is
Work done on the system
For second step
change in internal Energy of the system is
Work done on the system
Work done on the system is considered as Positive and vice-versa.
and from first law of thermodynamics
for first step
overall heat added
For overall Process Heat added is 0 J

Answer:
D)
The energy of the wave moves perpendicular to the direction the wave travels.
Explanation:
I had this question on USA test prep and this was the correct answer
Average speed =
(total distance)/(total time)
Average speed = (99+90)/(2+3)
That's (189 km) / (5 hr)
Average speed = 37.8 km/hr
I think it’s cause no change i think
Answer:
4.6×10^-7 m or 0.46nm
Explanation:
From
Wo= hc/λ
Where:
Wo= work function of the metal
h= planks constant
c= speed of light
λ= wavelength
λ= hc/Wo
λ= 6.6×10^-34 × 3×10^8/4.30×10^-19
λ= 4.6×10^-7 m
