A tube is open only at one end. A certain harmonic produced bythetube has a frequency of 485 Hz. Thenext higher harmonic has afrequency of 593 Hz. The speed of sound in air is 343 m/s.

(a) What is the integer nthatdescribes the harmonic whose frequency is 485 Hz?
1

(b) What is the length of the tube?

write a letter to the panel of judges asking for a new trail for Sarah good. In the letter, provide at least three reasons for the judges to grant Ms. Good a new trail and include specific quotes from the transcript below. write 200 words.

1. 1.The experimental rate law of a simple reaction A → B + C is v = k[A]. (a) Determine total order of the reaction. (b) Imagine initial conditions at which the rate equals v0. Calculate the change in the reaction rate that will be observed when the concentration of A will be tripled.

2.Calculate the activation energy for a first-order reaction if its rate constant increases from 10 s–1 to 100 s–1 as the temperature increases from 300 to 330 K.

3.Consider a simple first-order reaction A → B. If you start with solution of 0.1 mol/L A, it takes 20 s to go to a concentration of 0.05 mol/L of A. (a) What is the value of the rate constant for this reaction? (b) Calculate half-life of the reaction.

True or False (with explanation of why):

a. When a monopolist operates on the inelastic region of the market demand curve, it can always increase profit by producing less output.

b. When a monopolist operates on the elastic region of the market demand curve, it can always increase profit by producing more output

Digital transformation has gain attention in organisational change management studies, formulate 
an IS/IT change plan for the organisation that will help meet objectives. (NB: Your plan must 
include the key components of change management in digital transformation:
i. Define the goals and objectives of the transformation.
ii. Assess the current state of the organization and identify gaps requiring change.
iii. Create a roadmap for change that outlines the steps needed to reach the desired state.
iv. Indicate how you will implement and manage the change at each level of the 
organization.
v. Show how each of these components are essential to successfully navigate a digital 
transformation process. 

This week, as we begin our study of square roots, let's explore the life of Pythagoras and his contribution to the world of mathematics. Write one short paragraph (5–10 sentences) that provides us with a snapshot of one part of his life, his discoveries, or the famous theorem that we still use today. Please support with a detailed example.​

Hello! Do ask me questions! I am very open in helping students with their homework. I will explain why the answer is as such, how you can tackle similar questions in the future and simpler ways to remember techniques :) I can help with Math (algebra and calculus), Chemistry and Physics thank you!
