Answer:
La intensidad del campo eléctrico es 70312.5 
.
Explanation:
La perturbación que crea en torno a ella una carga eléctrica se representa mediante un vector denominado campo eléctrico.
Se dice que un campo eléctrico es uniforme en una región del espacio cuando la intensidad de dicho campo eléctrico es el mismo en todos los puntos de dicha región.
El campo eléctrico E creado por la carga puntual q en un punto cualquiera P se define como:
donde q es la carga creadora del campo, k es la constante electrostática y r es la distancia desde la carga fuente al punto P.
En este caso, los datos son:
- k= 9*10⁹
- q= 5*10⁻⁶ C
- r= 0.8 m
Reemplazando:
Resolviendo:
E= 70312.5

Answer:
It takes 3 minutes.
Explanation:
The distance between the two subways is 3 miles.
The train travels at an average speed of 60mph (miles per hour).
We have to convert hours to minutes and we do that by cancelling out the hours and replacing it with minutes.
There are 60 minutes in an hour so we use that, 1 hour/60 minutes and multiply it to the existing speed we have.
The result is 1 mile per minute.
We then multiply the miles by 3 since that is how much we want and we get 3 minutes.
The false statement would be :
C. constructive interference occurs when the crest of one wave overlaps the trough of another and their individual effects are reduced or cancelled out.
Constructive interference should be when the crest of one wave overlaps another and their individual effects are add up, becoming a single wave of increased amplitude<span />
Answer:
P is pressure ,rho(slanted p) is density,g is the acceleration due to gravity, v is velocity and h is height
