Answer:
Nystagmus
Explanation:
Nystagmus describes repetitive involuntary eye movements that have a variety of causes, including brain injury, inner ear damage, stroke, substance abuse and metabolic disorders.
Nystagmus can also be congenital, meaning they are present from birth. Early onset nystagmus is much more common than nystagmus acquired in later life. In general, nystagmus is relatively common.
Nystagmus causes eye movements in both horizontal and vertical directions, and is linked with poor vision and depth perception, and can cause dizziness and disorientation.
Answer:
<em>4.61 N</em>
<em></em>
Explanation:
masa = 0.5 kg
ángulo de inclinación = 20°
Peso normal de la masa = mg
donde m = masa
g = aceleración debido a la gravedad = 9.81 m/s^2
Peso normal = 0.5 x 9.81 = 4.905 N
Si la masa se mantiene en su lugar mediante una cuerda paralela al plano, y no hay fricción en la masa, entonces
La fuerza sobre la cuerda = peso normal x cos ∅
donde ∅ = 20 °
La fuerza sobre la cuerda = 4.905 x cos 20°
==><em> 4.61 N</em>
They hold everything together. They may be small, But they do the biggest part.
It is the copper penny as it is metal and wood, plastic, and glass do not conduct electricity.
