Answer:
Explanation:
The velocity of the neutrons is
The mass of a neutron is
So their momentum is
The relative uncertainty on the velocity is 2 %. Assuming that the mass of the neutron is known with negligible uncertainty, then the relative uncertainty on the momentum of the neutron is equal to the relative uncertainty on the velocity, so 2%. Therefore, the absolute uncertainty on the momentum is
Heisenber's uncertainty principle states that
where
is the uncertainty on the position
h is the Planck constant
Solving for , we find the minimum uncertainty on the position:
Answer:
Explanation:
Given
Charge of first Particle
Charge of second Particle
distance between them
magnetic field due to first charge at mid-way between two charged particles is
(away from it)
Electric field due to
(towards it)
(away from first charge)
Answer:
Solved
Explanation:
Free body diagram has been attached
and FBD we can say that
tension in c and b will be higher as T_1 helps to keep both the person steady.
So,
m_a=m_b=m_c= 65 kg and θ=25°
The term g×sinθ is the component of acceleration along the inclined surface
Similarly
putting the value of θ and mass we get
T_2= 269.207 N
T_1= 538.41 N
Answer:
however your doing it now?? ?? lol
