Hope i helped :)
Explanation:
Answer:
the total force vector, on test charge is points from origin to point C( 1, 1 )
Explanation:
Given the data in the question, as illustrated in the image below;
from the Image, OA = 1, OB = AC = 1
so using Pythagoras theorem
a² = b² + c²
a = √( b² + c² )
so
OC = √( OB² + AC² )
we substitute
OC = √( OA² + AC² )
OC = √( 1² + 1² )
OC = √( 1 + 1 )
OC = √2
Coordinate of C( 1, 1 )
Hence, the total force vector, on test charge is points from origin to point C( 1, 1 )
El sarampión: más de 200 millones
<span>El sarampión se caracteriza por causar marcas rojizas en la piel, altas fiebres y malestar general. Además, es también el causante de la segunda mayor pandemia de la historia. La muerte se produce por inflamación pulmonar o de las meninges. Actualmente la mayoría de la población está vacunada contra este mal, ya que entra dentro de la vacuna 'triple viral'. Se contagia mediante contacto directo y por el aire. </span>

1. Frequency is the number of complete waves that pass a point in a second. 2.Wavelength is the distance between two crests or two troughs. 3.Time period <span> is the time it takes for one complete wave to pass a given point. 4. Amplitude is the height of the wave. Hence option 4 is correct. </span>
