Answer: The other product of Chadwick's nuclear reaction was carbon-12.
Explanation:
The isotopic representation of an atom is:
where,
Z = Atomic number of the atom
A = Mass number of the atom
X = Symbol of the atom
In a nuclear reaction, the total mass and total atomic number remains the same.
For the given reaction:
To calculate A:
Total mass on reactant side = total mass on product side
9 + 4= A + 1
A = 12
To calculate Z:
Total atomic number on reactant side = total atomic number on product side
4 + 2 = Z + 0
Z = 6
The isotopic symbol is
. Thus The other product of Chadwick's nuclear reaction was carbon-12.
Answer:83.17 cm/s
Explanation:
Let positive x be negative direction and negative x be positive direction in this question
General equation of motion of SHM is
x= --------1
where is natural frequency of motion given by
=
Where K is spring constant
here A=23.7cm
And it is given it is again at 23.7 from equilibrium position having passed through the equilibrium once.
i.e. it covers this distance in sec
where T is the time period of oscillation i.e. returning to same place after T sec
therefore T=0.634 sec
differentiating equation 1 we get
v=cos
and =
=9.911rad/s
=
v=83.17 cm/s
Answer:
quark
Explanation:
neutrón= 1.675 x 10-27 kg
proton=1,673 x 10-27 kg
electron=9,11 x 10-31 kg
quark=7,13 - 14,26 · 10−30 kg
Ores are specifically defined as a type of rock wherein it contains essential. These minerals would then be extracted from the rock and would be used in various industries. One conventional way of overcoming the disadvantages of using ones is through the use of recycled aluminium products.
Answer:
Explanation:
No external force is acting on uranium nucleus so we can apply law of conservation of momentum . If M and m be the mass of bigger and smaller fragments respectively and V and v be their velocity after fission , Total momentum after fission = total momentum before fission
MV - mv = 0 , since the nucleus was at rest , its momentum before fission is zero . negative sign of mv is taken because smaller fragment will move in opposite direction to that of bigger fragment .
MV = mv
M / m = v / V
M > m
Hence,
v > V
So velocity of smaller fragment will be higher .
