What are the deadlines for Physics at the University of Bremen?

As I remember resolving power of an optical instrument is inversely proportional to the wavelength of light:

$R \propto \frac {1} {\lambda}$

So the ratio of their resolving powers:

$\frac {R_1} {R_2} = \frac {\lambda_2} {\lambda_1} = \frac {5000} {4000} = \frac {5} {4} = 1.25$

Ratio of resolving powers = 5 : 4 (or 1.25)

Hi.

Dont worry you have so much time to score good marks.

follow some strategy 

• Organic Chemistry: Focus on all the name reactions and their mechanisms. Write them down repeatedly until you remember them perfectly.
• Physical Chemistry: Similar to physics, create a master list of all formulas from chapters like Solutions, Chemical Kinetics, and Electrochemistry. Practice applying these formulas to textbook problems.
• Inorganic Chemistry: Read the textbook thoroughly for this part, focusing on trends and important points (e.g., p-block elements).

Not really. The electric dipole moment vector directs or points from the negative charge to the positive charge. But the electric field lines that a dipole creates will point away from the positive and move to the negative charge.

Yes, the cube, which is a closed surface containing only one electric dipole will make electric flux zero. This follows Gauss's Law when the total charge inside it is zero. The field lines entering the surface will exit, and that would result in zero net flux. 

The magnitude of each charge and the distance that separates them.
