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.

<h3>What is reaction time?</h3>
The reaction time of an organism is a measurement of how quickly it responds to a stimulus.
The time interval between the presentation of the stimulus and the manifestation of a suitable voluntary response in the subject is defined as RT.
In the following situations is reaction time exhibited is;
A. Jenny and Tina play jumping rope.
B. Ben and Ted play soccer and football .
D. Bovet and Cris perform aerobic exercises.
Hence,option A,B and D are correct.

Answer:
Explanation:
Given parameters:
Initial velocity = 8m/s
Final velocity = 2m/s
Time taken = 3seconds
Unknown and solution:
1. Is he accelerating or decelerating?
Tranh is obviously decelerating in this period. This is negative form of acceleration in which the speed reduces as the body comes to a stop.
Deceleration is a negative change in velocity with time i.e a body is reducing its velocity as time is changing.
2. What is the value?
Mathematically;
Deceleration = 
Deceleration = 
= -2m/s²
Answer:
Explanation:
let t be time since the second diamond is released
a) y = ½g(t + 1)²
b) y' = ½g(t)²
c)
25 = ½g(t + 1)² - ½gt²
25 = ½g(t² + 2t + 1) - ½gt²
25 = ½gt² + gt + ½g - ½gt²
25 = g(t + ½)
t + ½ = 25 / g
t = (25 / g) - ½
t = (25 / 9.8) - ½
t = 2.05102... ≈ 2.1 s
