cc
Explanation:
Using this formula E = mc2, which is the formula formulated by Albert Einstein to get the energy where E is the units of energy, m is the mass and c is the speed of light. We can say that 1 g is equivalent to 0.001 kg. The speed of light is 38<span>. Substituting these values to the formula, we can get 90 terajoules.</span>

Answer:
Percentage of first isotope = 69.152 %
Percentage of second isotope = 30.848 %
Explanation:
The formula for the calculation of the average atomic mass is:
Given that:
For first isotope:
Let % = x %
Mass = 62.9296 amu
For second isotope:
% = 100 - x % (Since, there are only two isotopes)
Mass = 64.9278 amu
Average mass = 63.546 amu
Thus,
Solving,
1.9982 x = 138.18
Thus,
<u>Percentage of first isotope = x = 69.152 %</u>
<u>Percentage of second isotope = 100 - x % = 30.848 %</u>
Let the person at the Left be A and Person at the right be B
then the force by person A will be
Pulling force + Frictional Force = the force by the person
which is,
20N+11N=29N
then the force by person B will be,
25N+5N=30N
1) the net force will be 30N-29N=1N
2) the force are unbalanced as the net force acting on the object is not zero.
3) the rope will move towards the right as there is a net force of 1N towards the right.
