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
