Question 6: Given a circuit as shown in the figure. Knowing R = 102 , R = 2002, the potential difference between the two ends of the 12V UAB circuit. Find readings of ammeter and voltmeter? Question 7: Given an electric circuit as shown in the figure. Know R = 32 , R = 52 . Voltmeter shows 3V . Find the ammeter readings and the potential difference between the two terminals A and B of the circuit?

Engineers find a new metal that is stronger than steel but much lighter. this material is also significantly cheaper than what is currently used for most aircraft, available in large quantities, and easy to manufacture. the engineers are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next?

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass

Me pl give an example of a collision in real life. use the law of conservation of energy to describe the transfer of momentum. be sure and discuss the momentum before and after the collision occurs. you will need at least 3 sentences to thoroughly answer this question.
