Guten Morgen ihr Lieben,
Ich bin 72 Jahre alt und bereite mich auf eine Prüfung vor, leider sind meine Physik Kenntnisse nicht mehr so gut wie früher.
Darum möchte ich euch bitten mir doch zu helfen.
Danke ihr Lieben.
Wünsche euch einen schönen Tag für heute trotz dem Wetter.

Loading...All moments should be calculated: Why are F2 and L2 not considered in this example? Moment = Force x Lever Arm… Does it have something to do with the fact that F2 points away from the pivot point and thus acts in the other direction? it's been resolved haha thanks
Hello, can someone help me? I used the binomial formula and wanted to summarize everything, but the solution still says something different at A.
The minute hand rotates at a significantly higher speed than the hour hand. At what exact moment (to the second) after 5 p.m. do the two hands form the first right angle? with an explanation please
Can someone please help me with this task, I don't understand it. Book: Math Numbers and Sizes Page: 162 I need help with this please
I just saw a video where someone calculated the mass of the Earth using formulas. He came up with a number in the end. I just wonder how because he only used formulas. In short, how does he get from a formula to a number
Now that this is at least the second question that needs to be used in the same formula, I will give you an overview of the physics formulas used in school as a basic prerequisite.

The wire and the battery together have a resistance of 0.1 ohm. (the two are connected in series)
At 4 volts voltage, a current of 4 V / 0.1 ohm = 40 A is expected.
Hi TrixiePumi,
to calculate the current intensity II flowing through the copper wire in a short circuit, we can use the Ohm law, which is:
I=U/R
Here, U is the voltage and R is the total resistance. In this case, we combine the voltage of the battery and the total resistance.
The totality of the resistors is composed of the internal resistance of the battery and the resistance of the copper wire:
RTotal =Rinside and outsideRwire=0,04 Ω+0,06 Ω=0,10 Ω
Now we put the values in the formula for current strength:
I=U/Rtotal = 4Volt/0,10 Ω = 40 A
The current which flows in the accumulator battery in the event of a short circuit is thus 40 amperes.
