Answer:
I think that when a book hits the ground its potential energy converts into kinetic energy and then kinetic energy is transformed into sound and heat energy.
Explanation:
If my math is right its A) 7
because 189 divided by 27 is 7
Infrared contains the least energy and ultraviolet contains the most energy. The energy of a wave is inversely proportional to its
Answer:
The weight will be 1/6 of whatever it is on Earth.
Explanation:
Remember F=ma
If the acceleration decreases by a factor of 6 while the mass stays constant, you can see the force (the weight) will also decrease by the same factor.
Not only astronomers, but all scientists use the technique of rock dating to determine the age of the universe. From the Big Bang Theory, all the celestial bodies were made at the same time. So, the age of the Earth is just the same with the age of the universe. So, they gather rocks deep down in the crust of the Earth and let it undergo radioactive decay. By determining the amount of radioactive material left and half-life, they could compute the age of the Earth.
