Asmall, metallic, solid cyllinder made of gold, has a radius of 2.00mm and a length of 3.00cm. the number of free electrons in each atom of gold is le (electrons in the conducting band.) the density of gold is 8.96 %㎡ and the molar mass of gold is 63.55 %01. use scientific notation for all of your answers. (1) (10 points) find the volume and the mass of the cyllinder, in s. i. units. (ii) (10 points) find the number of moles of gold and the number of gold atoms in the cyllinder. (iii) (10 points) find the maximum electric charge this material could have, if all the conduction electrons were to be removed, in s. i. units.

Aball is thrown upward. at a height of 10 meters above the ground, the ball has a potential energy of 50 joules (with the potential energy equal to zero at ground level) and is moving upward with a kinetic energy of 50 joules. what is the maximum height h reached by the ball? consider air friction to be negligible. 1. h ≈ 10 m 2. h ≈ 50 m 3. h ≈ 30 m 4. h ≈ 40 m 5. h ≈ 20 m 003 10.0 points which of the two object shown below has the greatest kinetic energy? a m b 1 2 m v 2v 1. kinetic energies are the same. 2. a 3. b 4. unable to determine. 004 10.0 points tim, with mass 74.6 kg, climbs a gymnasium rope a distance of 3.1 m. the acceleration of gravity is 9.8 m/s 2 . how much potential energy does tim gain? answer in units of j. 005 10.0 points a car is moving at 64 miles per hour. the kinetic energy of that car is 5 × 105 j. how much energy does the same car have when it moves at 111 miles per hour? answer in units of j. 006 10.0 points an 102 kg man climbs up a 1 m high flight of stairs. the acceleration of gravity is 9.81 m/s 2 . w

Which lists the fundamental forces in order, from strongest to weakest? strong nuclear, weak nuclear, electromagnetic, gravitational strong nuclear, electromagnetic, weak nuclear, gravitational gravitational, weak nuclear, electromagnetic, strong nuclear electromagnetic, gravitational, strong nuclear, weak nuclear

The combining of light nuclei is called blank. blank as in not actually blank. you know what im tryin to say.
