Please answer a and b thank you so much

1. a. In a diesel cycle the temperature at the beginning of compression is 870C. If r = 14, find the temperature at the end of the compression. (T2 = 761.550C)

b. If the temperature at the beginning and end of the expansion are 17950C and 6770C, respectively, what is the thermal efficiency of the cycle? Assume γ = 1.40. (ηth = 59.26%)
