Answer:
We apply an electric field in the negative y direction
Explanation:
Since A uniform magnetic field is in the positive z direction and A positively charged particle is moving in the positive x direction through the field, the magnetic force acting on the positively charged particle is in the positive y direction according to Fleming's right-hand rule.
For the net force on the particle to be zero, we apply an electric field in the negative y direction to create an electric force on the positively charged particle, so as to cancel out the magnetic force.
Answer:
Explanation:
Generally speaking, as the human population grows, our consumption of natural resources increases. More humans consume more freshwater, more land, more clothing, etc. Scientific and technological innovations mean that we are improving our efficiency at using and harvesting natural resources.

Pregunta completa:
Un barco va a una velocidad de 45 ml/h, luego el capitán ordena acelerar hasta que la velocidad hasta que la velocidad sea de 60 mll/h. si la operación dura 30 minutos.
A cual fue la aceleracion?
B qué distancia recorre?
Responder:
30 millas / hora
26.25 mi
Explicación:
Dado que :
Velocidad inicial, u = 45 mi / hr
Velocidad final, v = 60 mi / hr
Tiempo, t = 30 minutos = 30/60 = 0,5 h
Aceleración, a = cambio de velocidad con el tiempo;
a = (v - u) / t
a = (60 - 45) / 0,5
a = 15 / 0,5
a = 30 millas / h²
Recorrido de distancia, S
S = ut + 0.5at²
S = 45 (0,5) + 0,5 (30) (0,5²)
S = 22,5 + 3,75
S = 26,25 millas
