The bigger molecule has more interactions and hence the higher b.p. CH3CH2OCH2CH3 is a bigger molecule than CH4 and CH3CH3, so has more dispersion forces. It also has dipole-dipole forces due to the polarised C-O bonds. CH3OH and CH3CH2OH have hydrogen bonds due to the very electronegative O atom bonded to the H atom

Answer:
Explanation:
From the question we are told that:
Wavelength
Length of cell arm
Refraction of air at at 1.00 atm pressure
Generally the equation for Number of shifts is mathematically given by
Since
Therefore
The door's moment of inertia for rotation about a vertical axis inside the door, 14 cm from one edge is 4.205 kgm².
<h3>
Momnet of inertia about a vertical axis inside the door</h3>
The door's moment of inertia for rotation about a vertical axis inside the door, 14 cm from one edge is calculated as follows;
where;
- I, cm is the moment of inertia about central axis
- d is the distance from the edge
- M is mass of the door
<h3>Moment of inertia</h3>
Thus, the door's moment of inertia for rotation about a vertical axis inside the door, 14 cm from one edge is 4.205 kgm².
The complete question is below;

Answer:
The speed of electron is and the speed of proton is 2468.02 m/s.
Explanation:
Given that,
Electric field, E = 560 N/C
To find,
The speed of each particle (electrons and proton) 46.0 ns after being released.
Solution,
For electron,
The electric force is given by :
Let v is the speed of electron. It can be calculated using first equation of motion as :
u = 0 (at rest)
For proton,
The electric force is given by :
Let v is the speed of electron. It can be calculated using first equation of motion as :
u = 0 (at rest)
So, the speed of electron is and the speed of proton is 2468.02 m/s. Therefore, this is the required solution.
