It is a triangle structure
Answer:
EA = 180KJ
EB = 320KJ
Where EA and EB, are the energy absorbed by automobile A and by automobile B
Explanation:
The concept of momentum and energy is applied here as it relates to elastic and inelastic collision.
The detailed steps, mathematical manipulation and appropriate substitution is as shown in the attached file.
Answer:
Explanation:
t1 = 1000 F = 1460 R
t0 = 80 F = 540 R
T2 = 3600 R
The working substance has an available energy in reference to the 80F source of:
B1 = Q1 * (1 - T0 / T1)
B1 = 100 * (1 - 540 / 1460) = 63 BTU
The available energy of the heat from the heat wource at 3600 R is
B2 = Q1 * (1 - T0 / T2)
B2 = 100 * (1 - 540 / 3600) = 85 BTU
The reduction of available energy between the source and the 1460 R temperature is:
B3 = B2 - B1 = 85 - 63 = 22 BTU
