El ejercicio completo es el siguiente:
Ana piensa en qué se podría hacer para volver a juntar los globos tras el
experimento del vídeo. ¿Cuál crees que es la respuesta correcta?
A. Esperar un rato a que se pase el efecto
B. Colocar entre los dos globos un tercer globo frotado con lana
C. Colocar entre los dos globos un objeto no electrizado
D. Colocar entre los dos globos un imán
Answer:
La respuesta correcta es la opción C
Explanation:
Como los dos globos están separados porque tienen la misma carga eléctrica, ahora Ana debe colocar un objeto no electrizado entre ellos para que los dos globos se vuelvan a juntar, como el objeto no electrizado tiene carga distinta a la de los globos hará que rápidamente se vuelvan a juntar.
Answer:
Option C
The number of microcontinents decreased and the size increased
Explanation:
During the Proterozoic stage, it's expected that while the size of microcontinents increased, the reverse happens on the number to imply the number decreased. Therefore, option C is correct, the number of microcontinents decreased and the size increased
Answer:
True
Explanation:
It is possible to reduce/lessen the force that is acting on an object. For example, if you were pushing on a box and wanted to push less on the box, that would be possible.
Answer:
Δx = 2.76 x 10⁻³ m = 2.76 mm
Explanation:
The distance between any two consecutive dark or consecutive bright fringes is given by:
Δx = λL/d
where,
Δx = distance between first and second dark fringe = ?
λ = wavelength of light = 546.1 nm = 546.1 x 10⁻⁹ m
L = distance between slits = 1.35 m
d = slit separation = 0.267 mm = 2.67 x 10⁻⁴ m
Therefore,
Δx = (546.1 x 10⁻⁹ m)(1.35 m)/(2.67 x 10⁻⁴ m)
<u>Δx = 2.76 x 10⁻³ m = 2.76 mm</u>
Small opening if you were directions from the light to come from
