A particle of (mass= 4 g, charge%3 80 mC) moves in a region of space where the electric field is uniform and is given by E, =-2.5 N/C,
E = E, = 0. If the velocity of the particle at t = 0 is given by Vz =
276 m/s, v, = v, = 0, what is the speed of the particle at t = 2 s?

A service station has both self-service and full-service islands. On each island, there is a single regular unleaded pump with
two hoses. Let X denote the number of hoses being used on the self-service island at a particular time, and let Y denote the
number of hoses on the full-service island in use at that time. The joint pmf of X and Y appears in the accompanying
tabulation.

- You are an investor who receives daily price quotes for a stock. The span of a stock's price on a given day is the number of consecutive days, from the given day going backwards, on which its price was less than or equal to its price on the day we are considering. Thus, the Stock Span Problem is as follows: Given a series of daily price quotes for a stock, find the span of the stock on each day of the series. Assume you are given seven daily stock quotes: 3, 10, 4, 7, 9, 6, and 8. Assume further that these stock quotes are stored in the array quotes.

Each policyholder is given a number (state) and the policy premium is determined as a function of this state. A policy holder's state changes from year to year in response to the number of claims made by the policy holder. Suppose the number of claims made by a particular policyholder in any given year, is a Poisson random variable with parameter A. Let. si(k) be the next state of a policyholder who was in state i in the previous year and who made k claims in that year. The following table is a simplified Bonus-Malus system having 4 states.

The quantity of morphine in a given dose may vary, but one guideline is to use 0.1 mg of morphine for each kg of the patient's body mass. The time taken for half the quantity of morphine to be removed from the body is 2 hours. An exponential function can be used to model the amount of morphine in the body over time: ?=?0???A=A0ekt (note that ?k will be negative). Calculate the value of ?k for morphine. Write a Python function called MorphineModel, which takes two arguments: dose amount ?0A0 and time since last dose ?t, and returns the amount of morphine in the body at this time ?t. Add to your computer code so that you have a program which is an implementation of the following flowchart. Ensure that your code is well-communicated to a user of the program (via the print statements) and well-communicated to someone reading the code (via comments).arrow_forward
