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:
962291.57928 m²
Explanation:
= Pressure =
(full reflection)
I = Intensity =
P = Power =
c = Speed of light =
M = Mass of Sun =
m = Mass of ship = 1500 kg
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
Force of radiation is given by
This force will balance the gravitational force as stated in the question
The area of the must be 962291.57928 m²
Missing figure: find it in attachment.
Answer:
Force D
Explanation:
In order to answer the question, let's keep in mind that the force of gravity on an object on Earth is the attractive force exerted by the Earth on the object; its direction is always downward (towards the Earth's centre), and its magnitude is given by
F = mg
where m is the mass of the object and g is the acceleration of gravity.
It follows immediately that in the figure, the force of gravity is the only force acting downward: therefore, force D.
The other forces are called:
Force A: thrust (it is the forward force generated by the engines)
Force B: lift (it is the upward produced by the aerodynamics of the wings)
Force C: air resistance (it is the backward force due to the friction between the air and the surface of the plane)
