I saw an example of yahoo saying that 114,000,000= 0.114, so ima take a guess and say that the way in expressing 146,000,000 in gigadollars would be 0.146. I'm sorry if I am wrong. But if it is right give me a thanks so I could know if I was right or not.
The first notion of the number of molecules per atom <span>was calculated by Josef Loschmidt which he endeavored to complete in 1895. In his experiment, he determined the number of molecules in one cubic centimeter of gas under STP. this is equal to approx 2.6 x 10^19 molecules. The former is called "Loschmidt's Constant" instead.</span>
Answer:
P and S waves slow down when they reach this layer. The asthenosphere, also known as the magma chamber, is the uppermost component of the mantle. This layer is partially molten and is a ductile zone in a tectonically poor state.
It's almost hard and seismic waves move through the asthenosphere at a slow rate. The fragile lithosphere and the uppermost portion of the asthenosphere are assumed to be rigid.
seismic waves travel more quickly through denser materials and therefore generally travel more quickly with the depth it moves more slowly through a liquid than a solid. Molten areas within the Earth slow down P waves and stop S waves because their shearing motion cannot be transmitted through a liquid. Partially molten areas may slow down the P waves and attenuate or weaken S waves.
hope this helps...
Answer:
2.316e-3 and 3.47e-3
Explanation:
Now, at that angle, we look at the bright spots on the screen.
tan θ = x / L (x is the horizontal distance from the centre of the screen, L is distance to screen)
For small angles, we can approximate that tan θ = sin θ.
nλ / d = x / L so then
x = n λ L / d
First bright fringe, n = 1
x = (1) (641*10^-9 m) (3.65 m) / (1.01*10^-3 m) = 2.316e-3
For destructive interference (dark fringes), equation becomes:
x = (n - 0.5) λ L / d
Second dark fringe, n = 1.5
x = 1.5 (641*10^-9 m) (3.65 m) / (1.01*10^-3 m) = 3.47e-3
