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.
Increasing the pressure of gas is like exactly the same as increasing its concentration. If you have a given mass of gas, the way you increase its pressure is to squeeze it into a smaller volume.
Hope this helps!
I think that i am right about it all okay so dont ask why
Answer:
As per Coulomb's law we know that force between two charges is given as
F = \frac{kq_1q_2}{r^2}F=
r
2
kq
1
q
2
here we know that
q_1 = 2.5 \times 10^{-6} Cq
1
=2.5×10
−6
C
q_2 = -5.0 \times 10^{-6} Cq
2
=−5.0×10

C
r = 0.0050 mr=0.0050m
now from above formula we will have
F = \frac{(9 \times 10^9)(2.5 \times 10^{-6})(5 \times 10^{-6})}{(0.0050)^2}F=
(0.0050)

(9×10
9
)(2.5×10
−6
)(5×10
−6
)
F = 4500 NF=4500N
so they will attract towards each other as they are opposite in nature with force F = 4500 N
