Answer:
Option A, B and D
Explanation:
Jack can easily convince boss if he focus around two major aspects of the company
a) Revenue enhancement - Jack must outline the benefits of his research that can be used to improvise customer offerings and hence can be further used to devise more energy-efficient options to customer
b) Reduction in mistakes - Issues such as poor implementation can be avoided with better approach and understanding.
Hence, option A, B and D are correct
Answer:
The volume percent of graphite is 9.9%
Explanation:
Given;
weight percent of graphite, C = 3.1wt%
density of ferrite, 
= 7.9 g/cm³
density of graphite, 
= 2.3 g/cm³
Determine the mass fraction;
Determine the volume fraction;
Therefore, the volume percent of graphite is 9.9%
Explanation:
1. A sequence of instructions is stored in memory.
2. The memory address wherever the first instruction is found is copied to the instruction pointer.
3. The CPU sends the address within the instruction pointer to memory on the address bus.
4. The CPU sends a “read” signal to the control bus.
5. Memory responds by sending a copy of the state of the bits at that memory location on the
data bus, that the CPU then copies into its instruction register.
6. The instruction pointer is automatically incremented to contain the address of the next
instruction in memory.
7. The CPU executes the instruction within the instruction register.
8. Go to step 3
Steps 3, 4, and 5 are called an instruction fetch. Notice that steps 3 – 8 constitute a cycle, the instruction execution cycle. It is shown graphically below.
A DMA controller can generate memory addresses and initiate memory read or write cycles. It contains several hardware registers that can be written and read by the CPU. These include a memory address register, a byte count register, and one or more control registers.
