Ayoung's double plit apparatus is set up. a screen is positioned 1.6 m from the double slits and the spacing between the two slits is 0.04 mm. the distance between alternative bright fringes is 1.42 cm. find the light resourse wavelenght

11. you want to calculate the displacement of an object thrown over a bridge. using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

Copper has free electrons per cubic meter. a 71.0-cm length of 12-gauge copper wire that is 2.05 mm in diameter carries 4.85 a of current. (a) how much time does it take for an electron to travel the length of the wire? (b) repeat part (a) for 6-gauge copper wire (diameter 4.12 mm) of the same length that carries the same current. (c) generally speaking, how does changing the diameter of a wire that carries a given amount of current affect the drift velocity of the electrons in the wire?

Which accounts for an increase in the temperature of a gas that is kept a constant volume
