Answer:
The ignition delay in a diesel engine is defined as the time interval between the start of injection and the start of combustion. This delay period consists of (a) physical delay, wherein atomisation, vaporization and mixing of air fuel occur and (b) of chemical delay attributed to pre-combustion reactions. Physical and chemical delays occur simultaneously.

Answer:
C.A subscript cannot be an expression
Explanation:
The option C (A subscript cannot be an expression) is false
In this question, we are given
,
-
A certain list, L, contains a total of n numbers, not necessarily distinct, that are arranged in increasing order.
- L1 is the list consisting of the first n1 numbers in L.
- L2 is the list consisting of the last n2 numbers in L.
Explanation:
As per the information given in statement 1, 17 is a mode for L1 and 17 is a mode for L2.
Therefore, we can infer that
,
- 17 must occur in L1, either same or a greater number of times as any other number in L1.
- 17 must occur in L1, either same or a greater number of times as any other number in L2.
As all elements in L are in ascending order, we can also conclude that
-
Each number between last occurrence of 17 in L1 and the first occurrence of 17 in L2 must be equal to 17 only.
- Therefore, 17 occurs either same or greater number of times as any other number in L.
- Thus, 17 is a mode for L.
However, from this statement, we cannot conclude anything about the mode of L1, L2, or L.
Hence, statement 2 is not sufficient to answer the question.
Therefore, 17 is a mode for L1 and 17 is a mode for L2.
