A 1000 kg automobile is pulled by a horizontal tow line with a net force of 950 N. What is the acceleration of the auto? (Neglect friction.) A constant net force of 1500 N gives a toy rocket an acceleration of 2.5 m/s2. What is the mass of the rocket?
What are the physical principles behind how they might work? (Hint- there is both thermodynamic as well as light absorption considerations.
If a given element has a mass that is 5.81 times that oc 12 C how do I figure out the mass and the element. Do I just times 5.81 times 12.0107? Therefore it is Ga
