Answer:
128 m
Explanation:
From the question given above, the following data were obtained:
Horizontal velocity (u) = 40 m/s
Height (h) = 50 m
Acceleration due to gravity (g) = 9.8 m/s²
Horizontal distance (s) =?
Next, we shall determine the time taken for the package to get to the ground.
This can be obtained as follow:
Height (h) = 50 m
Acceleration due to gravity (g) = 9.8 m/s²
Time (t) =?
h = ½gt²
50 = ½ × 9.8 × t²
50 = 4.9 × t²
Divide both side by 4.9
t² = 50 / 4.9
t² = 10.2
Take the square root of both side
t = √10.2
t = 3.2 s
Finally, we shall determine where the package lands by calculating the horizontal distance travelled by the package after being dropped from the plane. This can be obtained as follow:
Horizontal velocity (u) = 40 m/s
Time (t) = 3.2 s
Horizontal distance (s) =?
s = ut
s = 40 × 3.2
s = 128 m
Therefore, the package will land at 128 m relative to the plane
38*10=380 N
To be more exact, 38 should be multiplied by 9.8 instead of 10.
As light from a star races through our atmosphere, it bounces and bumps through the different layers, bending the light before you see it. Since the hot and cold layers of air keep moving, the bending of the light changes too, which causes the star's appearance to wobble or twinkle.
Answer:
Entonces la velocidad de la motocicleta es 
Explanation:
La regla de tres simple es una operación que ayuda a resolver rápidamente problemas de proporcionalidad, teniendo tres valores conocidos y una incógnita.
Dos magnitudes son directamente proporcionales cuando al multiplicar o dividir una de ellas por un número, la otra queda multiplicada o dividida respectivamente por el mismo número. En otras palabras, dos magnitudes son directamente proporcionales si cuando aumenta una magnitud, también lo hace la otra en la misma proporción o cuando disminuye una magnitud, también lo hace la otra en la misma proporción.
Para resolver una regla directa de tres cuando las magnitudes son directamente proporcionales, se debe seguir la siguiente fórmula:
a ⇒ b
c ⇒ x
Entonces 
La regla directa de tres simple es la regla que se aplica en este caso donde hay un cambio de unidades. Para realizar esta conversión de unidades, primero debe saber que 1 m = 0.001 km. Entonces, si 0.001 km es 1 m, ¿cuántos kilómetros son 72 m?
km=0.072
Entonces:
Siendo 1 s=0.0002778 h:

This was given in our Chemistry subject so fortunately I hope this helps.
In mono culture farming, they produce a single specie of a livestock or plant in large number or quantity.
Yes it is very effective but producing a mass number of a single organism in a specific area will risk of endangering the existence of a certain and specific nutrient - this is because that large number of organism is basically eating the same thing.
This will actually lead to societal decision such as the founding of The Livestock conservancy and other environmental protection organization
