If silicic rock is found in a core sample, its location is likely underneath an ocean or a mountain.
Answer: Option A
<u>Explanation:</u>
Silicic rock are the type of rocks which are made up of silica and are located at the crust of the earth which is more likely to the core lying underneath and it extends all the way up to 30 km.
Its density is around 2 gm / cm^3 .One of the common example of silica is granite. So if the silicic rocks are found in a core it is more likely underneath the ocean or mountain.
Answer:
prevents pollution, reduces the need to harvest new raw materials, saves energy, reduce greenhouse gas
Answer:
20,000,000 N
Explanation:
First find the acceleration:
a = Δv / Δt
a = (0 − 40 m/s) / 0.010 s
a = -4000 m/s²
Next use Newton's second law to find the force on the car:
F = ma
F = (5000 kg) (-4000 m/s²)
F = -20,000,000 N
According to Newton's third law, the force on the wall is equal and opposite the force on the car.
F = 20,000,000 N
When naming isotopes, the number beside it indicates the mass number. Now mass number is the sum of protons and neutrons.
We know that the mass number of a stable Sulfur atom is 32, so we can rule out C as an isotope. The atomic number of Sulfur is 16 and that means that there are 16 protons. Now if we subtract 16 from 33, then that means there are 17 neutrons. So we can rule out D.
Phosphorus on the other hand has an atomic number of 15. If we subtract 15 from 31 we will have 16. That means that Phosphorus-31 has 16 neutrons.
The answer would then be A. Phosphorus 31.
