Aspacecraft in the shape of a long cylinder has a length of 100 m, and its mass with occupants is 1490kg. it has strayed too close to a black hole having a mass97 times that of the sun. the nose ofthe spacecraft points toward the black hole, and the distancebetween the nose and the center of the black hole is 10.0 km.

(a) determine the total force on thespacecraft.
(b) what is the difference in the gravitational fields acting onthe occupants in the nose of the ship and on those in the rear ofthe ship, farthest from the black hole? this difference inacceleration grows rapidly as the ship approaches the black hole. it puts the body of the ship under extreme tension and eventuallytears it apart.

Avoltage source vs = 10 v is in series with a resistor of 10 kohm. if the source transformation theorem is applied, what will the value of the current source be in ma ?

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?
