<span>Radians/second * seconds = Radians BUT the angular velocity is not constant in this case so we need to integrate ω over time. We know this integral is the area under the curve which we can find using the plot:
20rad/s*2s + (10+5) + 10*0.4 = 59 radians
59 radians * 1rev/2π radians = 59/2π = 9.4 revolutions</span>

Explicación:
¿Qué significa que un automóvil viaje con una rapidez de 45 [(Km.) ⁄ (Hr.)]?
Si se dice que un automóvil viaja a una velocidad de 45 km / h, entonces el automóvil cubre una distancia de 45 km en una hora. 45 km / h es una derivación de la velocidad de desplazamiento obtenida de la relación;
Velocidad = distancia / tiempo
Velocidad = 45 km / 1 h.
Distancia = velocidad × tiempo
Distancia = 45 km / h × 1 h
Distancia = 45 km
Por lo tanto, a esa velocidad, se cubrirá una distancia de 45 km por cada hora que se mueva.

Answer:
Check the explanation
Explanation:
The escape velocity is the velocity needed by any object to overcome the gravitational force of the planet on which it’s present. Now we know that the gravitational force is directly proportional to the mass of the planet and inversely proportional to the distance of the object from the center of planet.
If we keep the mass of earth constant and decrease the size of the earth than this will decrease the distance between the object and the center of the earth and thus the gravitational force that will act on the body will increase substantially which will in turn increase the value of the escape velocity.
The value of escape velocity will keep on increasing as the size of the earth will shrink till it reaches to a point when the value of escape velocity becomes more than the speed of light and since it’s impossible to travel with a speed greater than the speed of light and therefore at this point it will become impossible for a spacecraft to escape the earth.
Answer:
The thickness is

From the question we are told that
The wavelength of the of the rader waves is 
The index of refraction of the polymer is 
The thickness is mathematically represented as
