Consider a two-state system as shown:
E1 = 0.05 eV
E0 = 0 eV
The system is in a thermal reservoir at temperature T.
a) [4 points] What is the entropy of the system at a temperature of T = 0 K? Explain your reasoning.
b) [4 points] Find the approximate entropy of the system at a temperature of ? = 1010 K. Explain your reasoning.
c) [6 points] Find the temperature T at which the system is 4 times as likely to have energy E0 as it is to have energy E1.
d) [6 points] Suppose the temperature of the system is T = 300 K. Find the average energy of the system.

*Goal: Design a Security Awareness Training module for privileged users.
-You need to document what will go into it, and explain how it will be enforced/monitored/administered.
-talk about the components specific for Privileged Users and how the company will ensure they have proper training on how to use/access/safeguard their credentials.
-Talk about what the dangers are associated with Privileged users. Why would it be different than how a company needs to address regular user credentials?
**This is a tabletop excercise.
Look into Privileged Identity Credential Management.

Prepare the Cash Flows from Operating Activities section of the statement of cash flows, using the direct method. Refer to the Amount Descriptions list provided for the exact wording of the answer choices for text entries. In the operating activities section, use the minus sign to indicate cash outflows, decreases in cash and a net cash outflow, if required.
b. What does the direct method show about a company’s cash flows from operating activities that is not shown using the indirect method?

1. Use Excel Data Analysis to find the mean, median, and mode of the data set. Make sure that you clearly state or point out which numbers are which.
2.Assuming speeds are approximately normally distributed, use Data Analysis to construct a 95% confidence interval for the true mean speed of drivers in this construction zone. Interpret the interval.
3.Construct a 99% confidence interval for the true mean speed of drivers in this construction zone. Interpret the interval.
4.Compare the widths of the 95% and 99% confidence intervals.
5.What conclusions do you draw about the speeds people drive in this construction zone?

How does the enzyme-substrate complex actually work to lower the activation energy? I understand that that when the enzyme and substrate combine to form a complex, this is known as the transition state and in this state, the complex is unstable however it lowers the activation energy required. I just don't understand what about this complex lowers the activation energy
