4 0

Let's see

Find enclosed area of loop

\\ \rm\dashrightarrow \pi r^2

\\ \rm\dashrightarrow 3.14(0.04)^2

\\ \rm\dashrightarrow 0.005m^2

Now

\\ \rm\dashrightarrow \phi=BAcos\theta

  • We need B

\\ \rm\dashrightarrow 9.59\times 10^{-7}=B(0.005)cos75

\\ \rm\dashrightarrow 9.59\times 10^{-7}=0.0046B

\\ \rm\dashrightarrow B=2084.78\times 10^{-7}

\\ \rm\dashrightarrow B=2.08\times 10^{-4}T

\\ \rm\dashrightarrow B=0.208mT

En un instante pasa por A un cuerpo con MRU de 20 m/seg, 5 segundos después pasa en su persecución, por el mismo punto A otro cu
sukhopar [10]

Answer:

Los cuerpos se encuentran luego de 15 segundos a los 300 metros.

Explanation:

El movimiento rectilíneo uniforme (MRU) es el movimiento que describe un cuerpo o partícula a través de una línea recta a velocidad constante. Es decir, que en este caso el movimiento es lineal en una única dirección  y la velocidad de desplazamiento es constante.

La posición del cuerpo después de un tiempo se calcula a partir de la posición inicial y de la velocidad del cuerpo mediante la expresión:

x=x0+v⋅t

donde:

  • x0 es la posición inicial.
  • v es la velocidad que tiene el cuerpo a lo largo del movimiento.
  • t es el intervalo de tiempo durante el cual se mueve el cuerpo.

En este caso, si el tiempo empleado por el primer cuerpo es t, el del segundo que sale 5 segundos más tarde será t-5. Siendo la velocidad del primer cuerpo 20 m/s y la del segundo cuerpo 30 m/s, entones la posición de cada uno será:

x1 = 20 m/s* t

x2 = 30 m/s* (t - 5 s)

Ambos se encuentran cuando sus posiciones son iguales:

x2=x1

30*(t - 5) = 20*t

30*t - 30*5= 20*t

30*t - 150 = 20 t

30*t - 20*t= 150

10*t= 150

t= 150÷10

t=15 segundos

Reemplazando en la expresiones de posición obtienes:

x1 = 20 m/s* 15 s= 300 m

x2 = 30 m/s* (15 s - 5 s)= 300 m

<u><em>Los cuerpos se encuentran luego de 15 segundos a los 300 metros.</em></u>
