Answer:
atm
Explanation:
The pressure at the bottom of any liquid column is equal to product of density of the liquid , gravitational acceleration constant (g) and height of the water column
Thus,
Substituting the given values, we get -
kg/m3 m/s^2 meters
atm
Answer:
True
Explanation:
A cation is a positively charged ion, with fewer electrons than protons,
An anion is negatively charged, with more electrons than protons.
Answer:
a) A:170572.5 J
C: 55794.9J
b) 170572.5 J
c) 41.4413265306m
d) 2.7455874717m/s
Explanation:
a) Kinetic energy = 0.5*m*v²
KE at A = 0.5*420*28.5² = 170572.5 J
KE at C = 0.5*420*16.3² = 55794.9 J
b) Mechanical energy is the total kinetic energy plus potential energy at a point on the system. There is no potential energy at A.
ANSWER: 170572.5 J
c) v²=u²+2as
28.5²=2(9.8)s
812.25/19.6=s
s=41.4413265306m
d) h=height from part c, r=radius of loop
v²=u²+2as
v²=gr or a=v²/r
Ei=Ef
mgh=0.5mv²+mg(2r)
gh=0.5v²+2gr
h=0.5r+2r
h=5/2r
r=2/5h=(2/5)(41.4413265306)=16.5765306122
F=ma
mg=m(v²/r)
g=v²/r
v²=(9.8)(16.5765306122)
v=√162.45
=12.7455874717m/s
Answer:
Explanation:
Nuclear Fission -
The process of the splitting of atom , by radioactive decay process or by any collisional impact .
Sun contains many radioactive isotopes like , thorium , uranium , etc .
The nuclear fission process is an intrinsic property of the radioactive nuclides.
Nuclear Fusion -
The process , where two or more than two atomic nuclei combines to form one or more different atomic nuclei and subatomic particles .
The energy released in both the process is almost same ,
But on the surface of Sun , hydrogen is abundantly present , hence , hydrogen fusion is possible , so the dominant source of energy on the sun is Fusion .
