Afisherman of mass m = 97.6 kg is sitting in a canoe with mass m = 131 kg on a warm summer day. the canoe has length l = 4.60 m and he is sitting at the very end of the canoe. after several hours of not catching anything, he decides to try his luck from the other end of the boat, so he gets up and walks over to the other end of the canoe, then sits down again. assuming that the water applies no frictional force on the canoe, what is the magnitude of the) distance the canoe itself has traveled in this process? you may assume that the canoe is perfectly symmetric in its shape and mass distribution. enter a numerical answer below. accepted formats are numbers or "e" based scientific notation e. g. 0.23, -2, 106, 5.23e-8 enter answer here cm o of 4 attempts used check answer

You have been consulted by the mobile phone company hookup about a new augmented reality product called “brows”. they want to develop an alternative to google glasses, which, you recall, is a proposed new product which plans to superimpose a whole range of wireless google services over the user’s ordinary vision of the world. these appear in little circles and ovals, and let you phone people, take photographs, navigate across cities and inside buildings, find shops and update your social media. brows would do this too, but not be limited to special google services. the user would wear a small cylinder-shaped device designed to fit on top of their existing eyewear (glasses or sunglasses). it would project a reversed image onto the inside of the lenses, the reflection of which would be in focus for the user. instead of voice control, the user would control the device by eye and neck movements, which the device would track. the device would connect via bluetooth to the user’s phone, which would supply most of the computing power and wireless connectivity. hookup also wants to know what existing services would be most in demand, and which would not work well with brows. using your knowledge of augmented reality, wearable technology and interface design, is the project feasible? if not, why not? if feasible, how could the product need to be modified for a better experience?

Which best represents the law of conservation of mass ?

A5 foot by 5 foot box culvert is buried 6 feet beneath the surface of the ground. a crosssection of this very long culvert (into and out of the page) is illustrated below. assume that the soil in which the culvert is buried has the following properties: jt = 120 pcf, w = 12%, ko = 0.50, ka = 0.33, and kp = 3.00. calculate the total horizontal force per unit length of culvert (fh) felt on one of the vertical faces of the culvert.
