Answer:
17.66 kPa
Explanation:
The volume of water in the swimming pool is the product of its dimensions
V = 30 * 8.7 * 1.8 = 469.8 cubic meters
Let water density 
, and g = 9.81 m/s2 we can calculate the total weight of water in the swimming pool
The area of the bottom
A = 30 * 8.7 = 261 square meters
Therefore the pressure is its force over unit area
or 17.66 kPa
Answer:
Nuclear Fusion
Explanation:
when a star's core collapses, it has no outer layer of resources to use, so it uses the resources inside of it, nuclear fusion is a nuclear reaction in which atomic nuclei of low atomic number fuse to form a heavier nucleus with the release of energy.
Answer:
Extension of the wire is not indicated
Explanation:
Young modulus (YM)= (stress/Strain); Tensile Stress/tensile Strain
=> YM *Strain =Stress=F/A; A is cross sectional area and F is the force
(YM * Strain * A)/36 =F (Force developed in each wire)
F = (350 *e*0.0125)/12
