Answer:
Scientific theories allow scientists to make predictions.
Newtons 3rd law of motion states the every action has an equal and opposite reaction, so in space with no gravity and no friction the ship would move in what ever direction it was pushed forever, until it would reach some kind of gravitational pull.

Answer:
3097,5 kcal
Explanation:
Using the definition of power, which is work over time, where work is measured in Joules, we have that 100 watt = 100 J/sec. That means that an adult person radiates heat at the rate of 100 Joules per second. Since 1 hour has 3600 seconds, we must calculate the energy radiated in 36 hours as 100*3600*36 = 12960 kJ, where 1kJ=1000 J. Now all we need to do is to convert it in kcal. Note that 1kJ = 0.239006 kcal, so we need to multiply 12960*0.239006 = 3097,5 kcal. An adult person radiates 3097,5 kcal over a 36 h period
