To predict future climate, scientists use computer programs called climate models to understand how our planet is changing. Climate models work like a laboratory in a computer. They allow scientists to study how different factors interact to influence a region's climate.
Now a new evaluation of global climate models used to project Earth's future global average surface temperatures over the past half-century answers that question: most of the models have been quite accurate.
Answers are:
1. Exothermic
2. Endothermic
3. Pendulum
4. Bob
5. Period
6. Conservation of energy
7. Potential energy
8. Kinetic energy
9. Chemical energy
10. Nuclear energy
a = F/(m1+m2)
1.2 = F/48,000
F = 57,600N
a = F/(m1+m3)
a = 57,600/24,000
a = 2.4 m/s^2
How many atoms are in something determines it "mass"
