~ Physics HELP! ~ Please Look! ~

If anybody can help me with these questions i would be appreciative thanks



~Energy is released during a nuclear reaction due to a conservation between mass and energy. Mass is not onserved. The inital and final amounts are different. If atotal of 19g of mass were "missing", how much energy is released? Answer in units of J (jules)


~A passanger on an interplanertay express bus traveling at 0.19c takes 6 miutes slee by his watch. How long would you measure the passangers sleep to be. Answer in units of minutes

~Assume 11g of a substance marked as "pure energy" is annihilate by 11g of a second substance "anti pure energy", How long would the energy released power a city which uses 2*10&9 W of power? Answer in units of hours

~ A protons rest mass is 1.67*10^-27 (1.67 times 10 to the negative 27). Calculate its total energy if it is accelerated to a speed of 0.75c. Answer in units of J

~The annual energy requirment fot the unted states is on the order od 2.73*10^20 J. How many kilograms of matter would have to be releae as energy to meet this requirment? Answer in the units of KG

~The period of the earth around the sun is 1 year and its distance is 150 million km from the sun. An asteroid in a circular orbit arounf the sun is at a distance 581 million KM from the sun, Whats the period of the asteroid orbit?Answer in units of year

~(extension from above question) What is the orbital velocity of the asteroid? Assume there are 365 days in one year. Answer un units of m/s

~ Earths gravitational field is 8.05 N/kg at the altitude of the space shuttle. What is the size of force of attraction between a student of mass 48.5kg and Earth? Answer in units of N

P.S ~ If you know ayone who can help pleas advise me
