Solve for the unknown force of x. Then solve for the unknown force of y. Only use the mass of the boy when solving in the y direction. You will then be able find the magnitude and angle with Fx and Fy of the dad by forming a triangle.

I would just solve for the force of the dad. Since the sum of the forces are already restricted in the direction of x. For the magnitude and direction of the force of the dad, you can now use the sum of the forces in the y direction.

Were you given a diagram for this question?

By components, I mean in the x and y direction.

You should separate by components.

I would stick with the first equation. Remember that acceleration on the right hand side is that caused by the net force, which in this case is in the x direction.

I am trying to see how I can use the Schrödinger equation to quantify the changes in the intensity of light. My closest guess is using the time dependent pertubation theory

Why is the parabolic shape for the hole broader than that of the electron?

What does it mean for the holes to have mass? But they are not physically existent.

Hi, What are the rules that satisfy which combination of elements are semiconductors? First one is to satisfy the octet rule to form covalent bond. This can be easily checked by looking at the group number, which is indicative of the number of valence atoms. The other is the electronegativity...

From my understanding of semiconductors, we are able to create semiconductors by combining different group of elements that fulfill the octet rule to produce covalent bonds and where their electronegativities provide a energy band gap that is between that of a conductor and insulator. Why is the...

Can you create pure semiconductor quantum dots? I have seen composite ones that are created with elements in the group II-VI and III-V. Moreover, it saids that the size of the quantum dots must smaller than the Bohr Excitron Radius. From my understanding of the Bohr Exciton Radius is the...

Hi, Although I would like to the check all the threads that are being posted, I am particularly interested in a topics that discusses only about spectroscopy. Is there a way that I could receive emails of alert if the topic itself is being asked?

When visible light is being emanated to a quantum dot, why is it that you can see specific colors? I am not talking about the fluorescence that would occur when UV light is emanated.

Can combination elements in group I and group VII be a semiconductor? My thinking is that they form the octet rule just like group II and group VI elements.
