If it starts from 0m/s...
s=?
u=0
a=-10
t=8
s=ut +1/2at^2
so s=(0×8)+ (0.5×-10×64)
s=0+(32×-10)
s=32×-10
s=-320metres
600. I forgot the measurement. but 600 is correct
The correct answer is:
D. Extrusive rocks.
The explanation:
when extrusive igneous rocks form when magma reaches the Earth's surface a volcano and cools quickly. Most extrusive (volcanic) rocks have small crystals. Examples include basalt, rhyolite, andesite, and obsidian.
Answer:
The correct answer will be option-B.
Explanation:
A scientific hypothesis is the proposed perdition or idea which is based on the earlier works and knowledge related to the scientific issue. The hypothesis can be tested and proved on the basis of the experiments.
The proved hypothesis can either become law or theory after peer-reviewed by fellow scientists. If the hypothesis still has predictive capabilities help form another hypothesis. Such statements are known as the "theory".
Thus, Option-B is the correct answer.
For a total charge of Q coulomb is uniformly distributed along a rod 40cm in length, the electric field intensity 20cm away from the rod is mathematically given as
E1=1.598*10^11v/m
<h3>What is the e
lectric field intensity 20cm away from the
rod along its perpendicular
bisector?</h3>
Generally, the equation for the initial electric field intensity is mathematically given as
Therefore
Hence
E1=B*9*10^{13})/(10*110)*
E1=1.598*10^11v/m
In conclusion, the electric field intensity
E1=1.598*10^11v/m
