Which type of temperature measuring device can be used to record temperatures over a 7-day period?

We are reading and discussing early American literature in this class including works about the time of the Revolutionary War. The separation from Britain is now 250 years in the past. In a brief paragraph of at least three sentences, share how you celebrated America’s 250th birthday or how you would have liked to have celebrated it (if, for example, you were stuck at work on July 4, 2026). 

An artillery platform tested at Aberdeen Proving Grounds is evaluating a new explosive charge. The 25.6 kg shell is fired from a platform 31.8 m above sea-level at an angle of 37.2° above the horizontal. The muzzle velocity is 600 m/s and lands at a height of 10.2 m. Assuming no air resistance and using g = 9.81 m/s². How much further would the projectile have gone if it contained 9 % more kinetic energy?

Pascal’s Law is the fundamental principle behind which of the following?

What is the core idea of Pascal’s Law?

A sailing ship must travel from Port Alpha to Port Beta. The ship’s master has two different sail configurations available and must determine which performs better under different wind conditions. The sailing vessel, including its cargo, has a total mass of 45,000 kilograms. During performance trials, the ship’s master measures acceleration over a distance of 180 meters. Throughout the journey, there is a constant ocean current with a velocity of 2.0 meters per second flowing in the direction of travel. The ship has two sail configurations available: The square rigged sails that generate a force of 8,500 newtons when sailing into a headwind and 15,000 newtons with a tailwind. Lateen rigged sails that produce 11,200 newtons of force with a headwind and 12,800 newtons with a tailwind. For this analysis, assume water resistance is negligible and the ship starts from rest relative to the water. Calculate the acceleration of the ship with a lateen rig sail for a tailwind.
