If the force applied(Fa) is pushing down to chair friction goes up. if Fa pushing up, friction goes down. if Fa pushing sideways and the chair stays stationary, friction stay the same. if Fa push sideway and chair moves, friction goes down
<u></u><u> hybridization and 1 lone pair</u> is exhibited by the nitrogen atom in the following substance pairs are present on the nitrogen.
b. hybridization and 1 lone pair
<u>Explanation:</u>
The Nitrogen particle is hybridized with one crossover orbital involved by the solitary pair. Likewise, nitrogen is hybridized which implies that it has four half and half orbitals. The sub-atomic structure of water is predictable with a tetrahedral game plan of two solitary sets and two holding sets of electrons. Two of the hybridized orbitals cover with s orbitals from hydrogens to frame the two N-H sigma bonds.
Nitrogen utilizes orbitals to accomplish this geometry. Three of the mixtures are utilized to frame bonds to hydrogen and the fourth contains the solitary pair. Whereas lone pairs are the pairs of electron on atoms that don't take an interest in the holding bonding of two atoms. To distinguish solitary matches in a particle, make sense of the number of valence electrons of the molecule and subtract the number of electrons that have partaken in the holding.
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: The answer is 700kg
