Solution
In this question we have given
Charge,
Charge,
Charge,
Distance between Charge and ,d=43cm=.43m
Let the distance between charge and , is x
Therefore,distance between charge and , will be=(.43-x)
We know By Couloms law, Force on Charge due to charge which are seperated by distance d is given by following equation
............(1)
Here, K=
Therefore,
Force on Charge due to charge
..(2)
Similarly,
Force on Charge due to charge
..(2)
In equilibrium condition,
on solving we get
x=.277m
0r x=28cm
The distance between charge and , is 28cm
Answer:
Explanation:
The Work-Kinetic Energy Theorem states that the work done on a particle of mass "m", equals the particle's change in Kinetic Energy (final Kinetic Energy of the particle "" minus the initial Kinetic energy of the particle ""), and it is expressed as:
where we have used the explicit form of the KE of a particle of mass m and velocity . Of course, stands for the final velocity of the particle, and for the particle's initial velocity.
Yes it is possible, because the human skeleton will never disintegrate since it’s made of bone.
Since the system itself is giving off heat, this is a
reduction in the internal energy.
heat = - 25,000 J
Since work is being done on the system, therefore it is
an additional energy to the system. Work is given as:
work = - P dV
work = - 1.50 atm (6 L – 12 L)
work = 9 L atm
Since it is given that 1 L atm is equivalent to 101.3 J,
therefore the total energy added is:
energy due to work = 9 L atm (101.3 J / 1 L atm)
energy due to work = 911.7 J
Therefore the total change in internal energy is the sum
of heat and energy due to work:
Change in internal energy = - 25,000 J + 911.7 J
Change in internal energy = - 24,088.3 J
<span>Therefore, approximately 24.1 kJ of energy is lost by the
system in the total process.</span>
