A 1.5 kg block of wood is launched up a wooden ramp that has a 40-degree incline. The initial speed of the block is 12 m/s. The coefficient of static friction is 0.4 and the coefficient of kinetic friction is 0.20. Ignore air resistance.
A) Draw the incline with the block at the bottom of the ramp and at the top of its slide. Label with a coordinate system. List all known quantities.
B) Draw free body diagrams for the block sliding up the incline and down the incline. Label all forces and acceleration.
C) What is the normal force on the block?
D) What is the acceleration as the block moves up the ramp?
E) How far up the ramp does the block travel?
F) What is the static frictional force on the block when it stops? Is it enough to hold the block there?

Suppose a biochemist decided to use a HEPES buffer system to purify her His-tagged protein. HEPES is a sulfonic acid with a relevant pKa of 7.5. What volume of 1M NaOH would she need to add to a 250mL solution of 20mM HEPES to raise the pH from 7.5 to 8.0 (remember the HEPES is a weak acid).

Allied Merchandisers was organized on May 1. Macy Co. is a major customer (buyer) of Allied (seller) products. May 3 Allied made its first and only purchase of inventory for the period on May 3 for 2,000 units at a price of $11 cash per unit (for a total cost of $22,000). 5 Allied sold 1,000 of the units in inventory for $15 per unit (invoice total: $15,000) to Macy Co. under credit terms 2/10, n/60. The goods cost Allied $11,000. 7 Macy returns 100 units because they did not fit the customer’s needs (invoice amount: $1,500). Allied restores the units, which cost $1,100, to its inventory. 8 Macy discovers that 100 units are scuffed but are still of use and, therefore, keeps the units. Allied sends Macy a credit memorandum for $700 toward the original invoice amount to compensate for the damage. 15 Allied receives payment from Macy for the amount owed on the May 5 purchase; payment is net of returns, allowances, and any cash discount. Prepare journal entries to record the following transactions for Allied assuming it uses a perpetual inventory system and the gross method.

(Allied estimates returns using an adjusting entry at each year-end.)

Prepare the appropriate journal entries for Macy Co. to record each of the May transactions. Macy is a retailer that uses the gross method and a perpetual inventory system, and purchases these units for resale. (If no entry is required for a transaction/event, select "No journal entry required" in the first account field.)

Design a cybersecurity incident response plan for a company, including disaster recovery and business continuity elements (mitigation strategies and resilience). This should be the detailed plan you wish your organization has in place before a cyber incident or data breach happens in order to effectively respond and limit the cascading effects of the incident and also define the role of a cyber incident report? Who has the responsibility? When the incident has occurred at the bank, what data has been compromised and how the incident occurred? What type of damage it contains and the impacts, any legal implications? Did they restore the business continuity and did they remove the threat? What do you learn from the incident to prevent future attacks? Do you understand what actions worked well and those that did not (Documentation); what to do to improve the organization’s cybersecurity posture; and to keep the management informed and follow proper chain of command procedures?

Suppose that the Inverse Demand Curve for recreational Cannabis is given as: P = 14.60 – 0.40 [Qd] per gram. i. After determining the NORMAL Demand Curve from the Inverse demand curve above, determine the Quantities Demanded, Qd in Millions of grams, if the Price, P is reduced from $11.00 per gram to $10.00 per gram AND the value of the Price Elasticity of Demand over the “arc” of this change.

ii. Carefully explain how each of the “sign” and the “magnitude” of the elasticity determined in part i above would be interpreted? iii. Suppose that in response to a reduction in Price, P for Cannabis-based Gummi Bears from $12.00 to $10.00 per package results in a reduction in of 0.75 million grams at every price point from the original Demand Curve. Using this information, determine the elasticity of grams of Cannabis in response to the change in Price of the Gummi Bears. iv. Carefully explain how each of the “sign” of the elasticity determined allows us to describe the “type” of relationship between the Cannabis and Gummi Bears AND the interpretation of the “magnitude” of the elasticity?

Consider an array of 10 elements sorted in ascending order. Assume that you sort the table in descending order by running a sorting algorithm.

a) Count the exact number of changes made to the array (i.e. the number of operations of assignment T [...]=) if the bubble sort is applied (Assuming two assignments per swap).

b) Count the exact number of changes made to the array (i.e. the number of operations of assignment T [...]=) if heap-sort is applied (Assuming two assignments per swap).
