Ineed actual , not just the answers. i need explanations and formulas .
1. the mass of a certain neutron star is 2x10^30 kg and its radius is 6000m. what is the acceleration of gravity?
2. convert 25 ms to ns. 1ns=1x10^-6 ms.
3. erica kicks a soccer ball 12 m/s horizontally from the edge of the roof of a building which is 30 m high. how long will it take for the ball to reach the ground?
4. if a car accelerates from 24.4 km/h to 52.7 km/h in 8.5 seconds and the tires have an angular acceleration of 4.932 radians/sec^2, what is the radius of the tires?
5. if a gas occupies 2l at 32 degrees celsius, what temperature is required for the gas to occupy 12l of space?
include formulas and explanations so i can really learn this . you so

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 11.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.80 m/s; (b) he is then lifted at the constant speed of 4.80 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 78.0 kg rescue by the force lifting him during each stage

(a) calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 10.0 g. silver has 47 electrons per atom, and its molar mass is 107.87 g/mol. (b) imagine adding electrons to the pin until the negative charge has the very large value 1.00 mc. how many electrons are added for every 109 electrons already present
