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: Option B.
Strong nuclear force Gravity.
Explanation:
Nuclear force is the strongest force while Gravity is the weakest force. Strong nuclear force is the strongest force because it's act and hold atoms of matter together. It also binds neutrons and protons together to form atomic nuclei and it's has strength of 1.
Gravity is considered the weak force out of the four fundamental forces because it has a very small strength of 10^40 than electromagnetic force.
Let's use the equations for rectilinear motion. One particular equation is:
d = v₀t +(1/2)at²
Since it has been mentioned that the object starts from rest, then v₀ = 0. Substituting the values,
40 m = (0)(4 s) + (1/2)(a)(4 s)²
Solving for a,
a = 5 m/s²
<em>Therefore, the acceleration due to gravity is 5 m/s².</em>
Answer:
3.28 degree
Explanation:
We are given that
Distance between the ruled lines on a diffraction grating, d=1900nm=
Where 


We have to find the angular width of the gap between the first order spectrum and the second order spectrum.
We know that

Using the formula
m=1


Now, m=2





Hence, the angular width of the gap between the first order spectrum and the second order spectrum=3.28 degree
