I need help with an important problem that will most likely appear on my 10-hour test. I just can't seem to get this exercise right. It would be great if someone could explain the calculation method to me so I can understand it (please as soon as possible, the test is on Friday).
Thank you in advance!!!

Loading...Hello, My question is actually more complicated than what's written here. We previously explored the dipole in class. I know that light consists of electromagnetic waves, as do photons. I also know that light is emitted by energy or quantum leaps, but I don't understand to what extent this is an electromagnetic wave. We previously…
Hello, Could someone please help me with this task? (Power supply for a laser): In selected dental practices, drills are being replaced by laser systems. These lasers can emit extremely powerful light pulses that, upon impact, instantly vaporize a material. If the pulses are sufficiently short, the surrounding material is practically not heated, and no…
I have a physics problem and I'm stuck because I don't know where to start. Could you help me with problem b?
Hello, I have the following problem. Often, in physics, you can derive new relationships from two formulas. This time, for fun, I was looking at a problem on the laws of motion and found a general formula for determining acceleration (right). However, when I try to do this with units (left), I keep getting stuck,…
Formulas used:
Rges = R1 + R2 (series circuit)
Rges = (R1 + R2) / (R1 * R2) (parallel circuit)
Is mathematically the same as:
1/Rges = 1/R1 + 1/R2
R = U / I
Uges = U1 + U2 (series circuit)
Iges = I1 = I2
Uges = U1 = U2 (parallel circuit)
Iges = I1 + I2 “
Data without units
Links:
Rges = (80 + 40) / (80 * 40) = 3/80
Iges = 8 / (3/80) = 640/3
U(40Ohm) = 8
U(60Ohm) = 8 * (3/4)
I(part) = Iges * (1/3) = 320/3
Right:
Rges = 300 + (400 + 500) / (400 * 500) = 600009/2000 = unfär 300
Iges = 300 / 20 = 15
I(part) = Iges * (4/5) = 6
U(part) = 20
