Answer:
I believe if red, blue, and green light come together it would produce White light.
Answer:
(c) time required to travel = 8 sec
Explanation:
We have given the final position = -10 m on x axis
And the initial position =10 m
So total distance = 10-(-10)=20 m
The speed is given as 2.5 m/sec
We have tof ind the time required by the person to travel
Time is given by 
So the option (c) is correct option
A "screen" or even just a set of parallel bars are highly reflective to electromagnetic waves as long as the open spaces are small compared to the wavelengths.
"Grid" dishes work fine ... with less weight and less wind resistance ... for frequencies below about 3 GHz. (Wavelengths of at least 10 cm.)
(I even worked on a microwave system in South America where huge grid dishes were used on a 90-mile link.)
Answer:
Trabajo realizado = 600 Nm
Explanation:
Dados los siguientes datos;
Fuerza = 1000 Newton
Distancia = 0.6 metros
Para encontrar el trabajo realizado;
Sustituyendo en la ecuación, tenemos;

Trabajo realizado = 600 Nm
The answer is A and E.
Hope this helps! :D
