A student wanted to check her idea that a planet that is closer to the Sun receives more of the Sun’s energy than a planet that is farther away from the Sun. She placed a radiometer 50 cm away from a clamp light with a 150 –W lightbulb

To check her idea, she also needed to set up another clamp light and radiometer.

Which of the following setups would she use?

A. a clamp light with a 50-W lightbulb placed 25 cm from the radiometer

B. a clamp light with a 50-W lightbulb placed 50 cm from the radiometer

C. a clamp light with a 150-W lightbulb placed 25 cm from the radiometer

D. a clamp light with a 150-W lightbulb placed 50 cm from the radiometer

Acar is traveling at 53.0 mi/h on a horizontal highway. (a) if the coefficient of static friction between road and tires on a rainy day is 0.104, what is the minimum distance in which the car will stop?

Will you chech and finish these for me, because i am stumped with them.

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?
