Answer: Anthophobia
Explanation: A fear of flowers
Answer:
internal energy E 3716.35 j
cv = 12.47 J/K
S = 12.47 J/K
A = 0.29 J
Explanation:
given data:
Kr atomic number = 36
degree of freedom = 3
1) internal energy E =
=
2)
3)
4) A, Halmholtz free energy = E -TS = 37146.35 - 12.47*298 = 0.29 J
5)
For a system released from rest at θ = 0° when a constant couple moment M = 100 N.m is applied, the speed of the 10-kg block is mathematically given as
V=4.33m/s
<h3>What is the speed of the 10-kg block?</h3>
Generally, the equation for the workdone is mathematically given as
W=T tehta<dtheta
W=100(90*\pi/180)
W=1.5707*100
W=1.57Nm
The change in potential energy across the pulley
dP=mgh
dp=10*9.81*111.8
dp=10.97J
For the thrid position, potential energy is
dP=mg(0.3)
dP=17.658J
dP'=17.658J-13.125
dP'=-4.532J
For 2nd position dP=0
The change in Kinectic energy across the pulley\
dK.E=0.5mv^2
For 1st
dk.E=0.5m(10)^2
2nd
dK.E=0.5Iw^2
dK.E=0.5(7.5*10^-3)(v^2/0.05)^2
3rd
2nd=3rd
In conclusion,
157.07=dKE+dP.E
157.07=5v^2+ (7.5*10^-3)(v^2/0.05)^2+10.97-4.53
V=4.33m/s

Answer:
Dipole ion forces
Explanation:
Dipole ion forces are attractive forces between an ion (an atom that has lost or gained an electron, so it has a charge) and a polar molecule. A molecule is a dipole when there is an asymmetric distribution of electrons because the molecule is made up of atoms of different electronegativity. The ion then attaches to the part of the molecule that has its opposite charge: the positive end of the polar molecule faces the anion (negatively charged ion) and the negative end of the polar molecule faces the cation ( positively charged ion).
