Answer: B. 16
Explanation:
The given table:
x y
2.5 6.25
9.4 88.36
15.6 243.63
19.5 380.25
25.8 665.64
Here, we observed that value of y is the square value of x.
i.e. 
[For example 2.5²=6.25, 9.4²=88.36, 15.6²=243.63]
Put x=4, we get
Hence, the approximate value of y for x = 4 is 16.
So, the correct option is B. 16 .
Answer:
Questions involving accelerating objects, including those in free fall, can be solved using three equations
y = 1/2at2 + v0t + y0
v = v0 + at
vf2 = v02 + 2 a (y - y0)
In this case, only the first equation is needed.
Since the object is falling the final height is 0 meters, the initial height is 370 m, and the acceleration is -9.8ms-2
Since the object is dropped, the initial velocity is 0.
0 = 1/2(-9.8)t2 + 370. t = sqrt(370/4.9) = 8.69 s

Answer:
Cyberpunk has worst Physics
<span>Scientists have obtained most of this information from natural geological activity.
</span>S-waves and p-waves are seismic waves- the waves of energy that travel through the Earth as a result of an earthquake .Both P- and S-waves travel easily through solids, but S-waves cannot pass through liquids, and they cannot pass through the outer core. Scientists know that Earth’s outer core is liquid because s-waves are not able to pass through it.<span> When an earthquake occurs there is a “shadow zone” on the opposite side of the earth where no s-waves arrive.
</span>So, one of the reasons <span>why scientists believe the outer core is liquid is the s-wave shadow zone.</span>
