Ohm’s Law states that electrical current is proportional to voltage and therefore inversely proportional to resistance - V = I x R
Answer:
La potencia de la bombilla es de 1056 W.
Explanation:
La potencia de la bombilla se puede calcular usando la siguiente ecuación:
En donde:
P: es la potencia
I: es la corriente = 2,4 A
V: es la diferencia de potencial = 440 V
Entonces, la potencia es:
Por lo tanto, la potencia de la bombilla es de 1056 W.

Answer:
b
Explanation:
because a elastic band uses elastic energy
The van's AVERAGE speed on the way up the hill is
(1/2) (20 + 12) = (1/2) (32) = 16 m/s .
At an average speed of 16 m/s, it travels
(16 m/s) x (8 s) = 128 meters in 8 seconds.
Im not sure what are you asking about. But in physic/ mechanic usually when the object against gravity, its deceleration but when the object follow the gravity its acceleration
Also usually when the object move to the left side the speed will be negative (-) this is probably because of deceleration? since deceleration = -acceleration.
