A bunch of needles fell on a basket of feathers. What is the best method to do to separate the needles from the feathers without hurting yourself? Give a brief and exact explaination.
Archie designs an arch of a certain width and height to serve as an outdoor sculpture in a park. To achieve the size and shape for the strongest possible arch, he suspends a chain from two equally elevated supports as far apart as the arch is wide and allows the chain to hang as low as the arch is high. He then designs the arch to have exactly the inverted shape of the hanging chain. Explain why.

Soft ground lessens the pressure by conforming to the shape of our feet. Soft ground absorbs the impact, minimizing the force. Sturdy ground has a very rough surface, which causes pain on our feet. Stepping on a sturdy ground gives the maximum normal force, which causes pain on our feet.arrow_forward

However, since there are some things stored next to the wall you decide to ignore the advice and set the base of the ladder out half its length from the wall instead. The ladder is sitting on slippery old snow but It still feels safe when you start up to clear your gutters after a week of storms. After you climb on you have added your weight to the ladder. Which of these is a likely result? You go about halfway up, the bottom starts to slip away from the wall as you lean forward to hold on, the ladder rotates faster and falls down completely. You go up one rung and the base slips away from the wall. Nothing happens. It cannot slip once you are on it because your weight increases the friction. It slips a little when you first get on, so a friend adds weight to the base. Once you are near the top it is very stable and cannot slip.arrow_forwardAn automobile tire is shown in the figure below.

- Imagine we have created layers of ice on the surface of a platform and then propped it up at an angle of 10° with the ground. This makes a ramp 10 ft long from one end to the other. We then place the 5 kg cube at the top of the ramp and let it go. How long will it take for the cube to reach the end of the 10 ft ramp?arrow_forwardThe owner of a company that manufactures drinking cups decides it would be impressive to build an inground swimming pool that is a scaled up version of her best selling cup.
