Asinusoidal voltage δν= 37.5 sin( 100t), where δν is in volts and t is in seconds, is applied to a series rlc circuit with l-140 mh, c 99.0 μf. and r 63.0 ω. (a) what is the impedance (in ω) of the circuit? 107 (b) what is the maximum current (in a)? 350 determine the numerical value for ω (in rad/s) in the equation i-imax sin(at- 100 determine the numerical value for φ (in rad) in the equation i-imax sin(wt-d) (c) rad/s (d) 944 rad (e) what if? for what value of the inductance (in h) in the circuit would the current lag the voltage by the same angle ф as that found in part (d)? (f) what would be the maximum current (in a) in the circuit in this case?

How many seconds does it take a pebble released from rest off a bridge to fall 29.4 m ? what is the pebble's speed when it has fallen 29.4 m ?

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?

Standing side by side ,you and a friend step off a bridge at different times and fall for 1.6s to the water below. your friend goes first, and you follow after he has dropped a distance of 2.0m. when your friend hits the water, is the seperation between the two of you 2.0m or more than 2.0m? verify your answer with a calculation.
