Gabriel desplaza 2,5 m una caja de 40 kg de masa sobre

Physics
1 answer:
soldier1979 [14.2K]3 years ago
7 0

Answer:

El trabajo es  550 n*N

Explanation:

El trabajo se define como un movimiento de una masa al aplicarle una fuerza.

De tal forma que lo podemos escribir como:

W = F*d

Donde se asume que la fuerza se aplica en la misma direccion que el movimiento.

En este caso, sabemos que la caja se mueve una distancia d = 2.5m

Y la fuerza aplicada es 220 N, (la fuerza es paralela a la superficie, entonces se aplica en la misma direccion en la que la caja se mueve)

Entonces el trabajo sera:

W = 2.5m*220N = 550 n*N

The electrostatic force between the two ions is 2.9\cdot 10^{-10} N

Explanation:

The electrostatic force between two charged particle is given by Coulomb's law:

F=k\frac{q_1 q_2}{r^2}

where

k=8.99\cdot 10^9 Nm^{-2}C^{-2} is the Coulomb's constant

q_1, q_2 are the two charges

r is the separation between the two charges

In this problem, the ion of sodium has a charge of

q_1 = +e = +1.6\cdot 10^{-19} C

while the ion of chlorine has a charge of

q_2 = -e = -1.6\cdot 10^{-19}C

And the distance between the two ions is

r=282 pm = 282\cdot 10^{-12} m

Substituting, we find the electrostatic force between the two ions:

F=(8.99\cdot 10^9) \frac{(1.6\cdot 10^{-19})(-1.6\cdot 10^{-19})}{(282\cdot 10^{-12})^2}=-2.9\cdot 10^{-10} N

where the negative sign simply means that the force is attractive, since the two ions have opposite charge.

A beam of white light enters a prism of crown glass (n = 1.5) from air (n = 1.00). Once inside, the colors in the light disperse
eduard

Answer:

= 2.33

Explanation:

.According to snell's law:

n1sin i = n2sin r ,

where n1 is refractive index of the medium in which incident ray is travelling, n2 is the refractive index of the medium in which refracted ray is travelling,

i is angle of incidence,

r is angle of refraction.

Given that,

n1 = 1,

i = 51 degrees,

r = 19.5 degrees. ,

n2= ?

So,

1*sin 51 = n2 sin 19.5  

=> n2 = sin51 / sin19.5

 = 2.33
