Should be D bcs i took this same exact test yesterday
Answer:
Yes
Explanation:
It is possible for sedimentary rocks to be converted to igneous rocks. Under conditions of high temperature and pressure, sedimentary rocks can be broken down into igneous rock by melting this rock type.
When the rock is broken down, it forms melt which when cooled and solidifies will form igneous rocks.
Sedimentary rocks are formed from the breaking down of pre-existing rocks through the action of weathering, erosion and sediment transportation. Within a basin, the sediments are compacted and lithified.
When this is subjected to intense pressure and temperature, the rock hardens and might further break down to melt.
Answer:
a) wavelengths seen decrease
, b) λ’/λ = 0.9998
Explanation:
a) This is a relativistic doppler effect problem that is described by
f’= f₀ √ (1+ v / c) / √ (1- v / c)
The speed of light be related to wavelength and frequency
c = λ f
f = c /λ
We replace
c /λ’= c /λ √ (1+ v / c) / √(1- v / c)
λ’= λ √ [(1-v / c) / (1 + v / c)]
This expression gives us the wavelength depends on the speed of the premiere with respect to the Earth, as the estuary approaches the Earth the speed is positive
We can see that at the root it is less than 1 whereby the wavelengths seen decrease
b) we reduce the speed to m / s
v = 30 km / s = 3 10⁴ m / s
Change is
λ’/λ = √ [(1-v / c) / (1 + v / c)]
λ’/ λ = √ [(1- 3 10⁴/3 10⁸) / (1 + 3 10⁴/3 10⁸)]
λ’/ λ = √ (0.9999 / 1.0001)
λ’/λ = 0.9998
I would say a because that is the only one that makes sense but I’m not 100% sure
the answer is sex drive, I just took the test
