HURRY PLEASE I’ll mark you as brainliest An engineering student is gathering data on the motion of a model car traveling down a ramp. If energy is conserved, the
potential energy of the car at the top of the ramp should equal the kinetic energy of the car at the bottom of the ramp. After
the first trial, the student calculates that the kinetic energy at the bottom of the ramp is less than the potential energy at the
top of the ramp. Which of the following can best explain this difference?

A. The student did not measure the increase in velocity.
B. The measured mass of the car was greater than the actual mass.
C. The measured height of the ramp was greater than the actual heig
D. The student did not include the loss of heat energy.

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?
