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: D Minarel extraction cannot be done in ways that does not completely destroy the environment
Explanation: Hope this helps !!
The force needed to overcome sliding friction is more than the force needed to overcome rolling friction or static or even fluid
Yes, this is accurate. While "dark matter" might exist, it is still more of a theory, it is not yet defined properly. As far as we truthfully know, the entire universe is just matter and energy.
Answer:
Heat capacity is the amount of heat required to raise the temperature of an object by 1oC. The specific heat of a substance is the amount of energy required to raise the temperature of 1 gram of the substance by 1oC.
Explanation:
The answer is above.
