Un elicottero si muove alla velocità di 95 km/h parallelamente al suolo. Dopo 35 secondi, ha deviato la sua rotta di 35 gradi, raggiungendo una velocità di 72 km/h. Calcola il modulo della variazione di velocità. Calcola il modulo dell'accelerazione media nell'intervallo di tempo di 35 s.

What is work? how much work is done to move an object 0 meters?

The place you get your hair cut has two nearly parallel mirrors 6.00 m apart. as you sit in the chair, your head is 2.00 m from the nearer mirror. looking toward this mirror, you first see your face and then, farther away, the back of your head. (the mirrors need to be slightly nonparallel for you to be able to see the back of your head, but you can treat them as parallel in this problem.) how far away does the back of your head appear to be?

A2.0 μf capacitor and a 4.0 μf capacitor are connected in series across a 0.827-kv potential. the charged capacitors are then disconnected from the source and connected to each other with terminals of like sign together. find the voltage across each capacitor.
