Metal bar is aligned along East- West direction and it is dropped vertically down
So its velocity is along -Z direction,
Now the Earth's magnetic field is towards north so its towards +Y direction
now we have formula for force on a moving charge
v = - z direction
B = + y direction
now by the above formula
So force is towards East
so all positive charge is towards East end
La velocidad correcta de la luz en el vacío es 300.000 km/s .
La distancia = (velocidad) x (duración de tiempo)
Duración de tiempo = 494 segundos, porque cada minuto = 60 segundos
La distancia = (300.000 km/s) x (494 s)
<em>La distancia = 148.200.000 km</em>
The answer is
D. in a straightforward, objective manner
Answer:
Explanation:
In a thunderstorm the lightening is seen first then the roar of the lightening is heard because of the fact that speed of the light is much greater than the speed of the sound.
Given that:
Relation
M= 7 miles
t=?
where:
t= time in seconds
M= distance in miles
Now,
Putting the given values in the relation above
