Answer:
density ρ = mass / volume
ρ = 100 g / 11.2 cm^3 = 8.93 g/cm^3
Probably copper because a value given for Cu is 8.89 g/cm^3
Answer:
The energy that drives this movement is heat within the earth, this heat comes from two main sources which are;
1) residual heat left over from the formation of our planet billions of years ago.
2) The radioactive decay of naturally occurring chemical elements (notably uranium, thorium, and potassium ) in the earth releases energy in the form of heat. These two sources of heat warm Earth’s mantle and cause it to rise and sink, this rising and sinking creates a convectional movement of earth mantle.
Answer:
The absorption lines will shift to the red (become longer).
This is because of the extra distance that a wavelength λ must travel between the vibrations of the source producing the spectrum.
Note that the Doppler effect of the source is slightly different for light waves than it is for sound waves because sound waves require a medium in which to travel while light waves do not require such a medium (example air).
Answer:
continual drift
Explanation:
it exsplain why the tectonic plates move
Answer:
Graph 1 matches with B, 2 with A, and 3 with C.
Explanation:
Graph 2 shows a car whose distance part of the graph is not going up or down, while the time going up. That means that the car is stopped. Graph 1 shows a straight line, meaning that the car is traveling at a constant speed. Graph 3 is a curved line, meaning the speed of the car is changing somehow, and since the line is becoming more horizontal, the car is getting slower.
