Why am I adding the vectors here?
ByYakuzi
the vector V maps point A to point B. Determine the coordinates of point B a) A(2/1/-5). V (2/1/0) The solution states that a = (3/2/-5). But the formula for AB goes (b1–a1) etc. So it would be (b1+a1) but why
Zero effect and zero rate protocol?
Hello, At school, we conducted an experiment on the topic of background effect and background rate. We used a "Ranger" radiation meter and a meter holder. We measured the values (pulses for 3 minutes) at various locations: Boys' restroom: 252 Outside: 168 Hallway: 115 In the bag: 127 Stairs: 117 Why are the values high…

Difference and similarity between potential and tension energy?
Can someone please tell me what the difference and similarity is between potential and tension energy?
Camera Obscura: Why does the image become blurrier the larger the hole?
The larger the hole, the more light rays pass through the aperture = the optical image becomes brighter But why does it become blurry? Is my reasoning correct? Since more light rays pass through a larger hole, the optical image becomes blurry. Compared to a smaller hole, the light rays don't converge at a common…
Dissolve compound in water?
How do you solve problems like this? I'm always overwhelmed when it comes to solving such problems.
sy(t) = 1/2 * g * t²
g ist die Fallbeschleunigung (Konstante). 0,5*g kannst du also leicht ausrechnen.
Bei einer Auswertung eines Experimentes ist sy (Fallhöhe) normalerweise vorgegeben und t ist die Messgröße. Wenn ihr also sy/t² ausrechnet, dann müsste ein konstanter Wert von 0,5g herauskommen (ca. 5 m/s²).
… wenn man k rechnerisch bestimmen soll, dann braucht man entweder experimentelle Daten oder man integriert die Bewegungsgleichung vy = g·t (dann ergibt sich k = (1/2)·g)
