Three forces act on an object (at the origin of a rectangular coordinate system). Force one, F1, has a magnitude of 5.81 N and a direction Theta1 = 77.0 degrees, force two, F2, has a magnitude of 4.88 N and a direction of Theta2, = 156 degrees, and a force three F3, has a magnitude of 4.52 N and a direction of Theta 3 = 289 degrees. add these three vectors using the component method of vector addition. Call the resultant vector F and write the answer in component form (ie using unit vectors). then calculate the magnitude and direction of the vector F.

If two metal balls each have a charge of -10^-6 c and the repulsive force between them is 1 n, how far apart are they? (coulomb's constant is k = 9.0x 10^9 n-m^2/c^2? 9.5 m 9.0 mm 9.5 cm 0.9 m .

In physics the desire of an object to keep doing what it is doing is termed?

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?
