1. Chasing Sticks, an online pet supplies store, has the following in their financial statements for 2024 and 2025: 2025 Sales: $6.5 million 2024 Sales: $4 million A careful reading of the financials shows that $3 million of their 2025 sales come from a new channel – 20 brick and mortar stores the company didn’t have in 2024 and which have only been open for 10 months. What is their overall sales increase in 2025? What is their comp sales increase in 2024? Based on these numbers, how would you evaluate the health and growth of this chain?
QUESTIONS (PART II) 3. A plane wave with a peak electric field amplitude of 3 [V/m] propagates through a lossless, nonmagnetic medium and has an average power density of 22 [mW/m²]. Find the relative permittivity $\epsilon_r$ of the medium. 4. A 10 [GHz] uniform plane wave is normally incident from free-space onto an ocean surface. If the power density of the incident wave is 100 [mW/m²] and the seawater has $\epsilon_r = 80$ and loss tangent of 0.56, calculate the time-average power density, (a) just below the surface (b) at a depth of 1 [cm].
3. The fracture toughness of a material increases with increasing temperature.
The aim of the best-cost provider strategy is to create a competitive advantage by Multiple Choice translating its best-cost status into achieving the highest profit margins of any firm in the industry. incorporating attractive or upscale product attributes at a lower cost than rivals. attracting buyers on the basis of having the industry's overall best-performing product at a price that is slightly below the industry-average price. offering buyers the industry's best-performing product at the best cost and best (lowest) price in the industry.

Hint 1. How to approach the problem Light travels at a constant speed; therefore, you can use the formula for the distance traveled in a certain amount of time by an object moving at constant speed. Before performing any calculations, it is often recommended, although it is not strictly necessary, to convert all quantities to their fundamental units rather than to multiples of the fundamental unit. Hint 2. Find how many seconds it takes light to travel the given distance Given that the speed of light in vacuum is $3.00 \times 10^8$ m/s, how many seconds does it take light to travel a distance of 6.70 km ? Express your answer numerically in seconds. ? View Available Hint(s) 22333 s Submit Previous Answers X Incorrect; Try Again; 8 attempts remaining
