Answer:
Su padre necesita aplicar una fuerza de 20 newtons en la misma dirección que la fuerza aplicada por su hija.
Explanation:
Asúmase que el baúl se mueve en una superficie horizontal. La fuerza de rozamiento dada por el problema es la fuerza de rozamiento estático máximo, se requiere una fuerza externa antiparalela a la fuerza de rozamiento estático máximo para que el baúl se empiece a mover. La ecuación de equilibrio de fuerzas horizontales sobre el baúl es:
Donde:
- Fuerza externa aplicada sobre el baúl, medida en newtons.
- Fuerza de rozamiento estático máximo, medida en newtons.
Se despeja la fuerza externa:
Si 
, entonces:
Si la niña solo logra ejercer una fuerza de 30 newtons, su padre necesita aplicar una fuerza de 20 newtons paralela a aquella fuerza.
3.51 × 10^-7m
Explanation:
Refractive index = wavelength of the light in air ÷ wavelength in the medium
wavelength in the medium = wavelength of the light in air ÷ refractive index
= 5.4 * 10^-7 ÷ 1.54
= 3.51 × 10^-7m
Well the variation i'd different beak types was due to forced evolution. This was caused because the different finches of the different islands had different food sources. Like one species had a very broad beak for crushing shells of nuts, where as on another island a bird might have a longer beak due digging up grubs and other insects. But if one bird traveled to a different island then it might starve. Because it is not equipped to survive on that island.
Hope that this helps. Its been a few years but I am pretty sure that this is still accurate. Good luck!
The answer is 2/3
In the past, they even owned about 9/10 of the nation's total wealth. Back then, most capital goes to whoever owned land and any structura businesses.
Nowdays, people could even find income just through our internet and computers without any significant amount of capital, which make the national wealth spread more evenly.
Answer:
Spring constant = 48 N/m
Explanation:
Given the following data;
Mass = 0.60 kg
Force = 1.2 N
Distortion = 0.025 m
To find the spring constant;
Mathematically, the force exerted on a spring to cause a distortion or an extension is given by the formula;
Force = spring constant * distortion
Substituting into the formula, we have;
1.2 = spring constant * 0.025
Spring constant = 1.2/0.025
Spring constant = 48 N/m
