Answer:

magnitude of angular momentum of the coconut after t = 1 s is

L = 1930.4 kg m^2/s

Explanation:

Since it is dropped at the instant when it is at overhead position

so we will have

v_x = 6.61 m/s

now vertical speed of the coconut after t = 1 s

v_y = 0 - gt

v_y = -9.8 m/s

now its displacement in x direction is given as

x = 6.61 (1) = 6.61 m

height of the coconut after t = 1 s

y = 21.4 - \frac{1}{2}gt^2

y = 21.4 - \frac{1}{2}(9.81)(1^2)

y = 16.5 m

now angular momentum is given as

L = \vec r \times m\vec v

now we have

L = (6.61 \hat i + 16.5 \hat j)\times (11.1)(6.61 \hat i - 9.81\hat j)

L = -719.8 \hat k - 1210.6\hat k

so magnitude of angular momentum of the coconut after t = 1 s is

L = 1930.4 kg m^2/s

How do we determine the conditions that existed in the very early universe? A We can only guess at the conditions, since we have
lakkis [162]

Answer:

D By looking all the way to the cosmological horizon, we can see the actual conditions that prevailed all the way back to the first instant of the Big Bang.

Explanation:

Astrophysicists are able to determine the conditions that existed in the early universe, by using instruments such as telescopes to observe and study cosmic horizons. More ideas about the early universe can be found from the thermal light present in cosmic backgrounds.

Scientists study these details that provide an insight into the conditions that existed so many years ago. They have been able to determine that the Big Bang involved so many collisions from these observations.

If the man pushes with a force of 2000N and friction is 500N, what is the resultant force?
alexandr402 [8]

Answer:

Explanation:

If the force of 2000 N is directed towards the right and the friction is directed towards the left, the 2000 N force is positive and the other is negative. To find the resultant force:

2000 - 500 = 1500 N to the right

Que unidad de medida se utiliza para expresar la capacidad o volumen de un objeto? Da un ejemplo
galina1969 [7]

Answer:

<em>Explicado a continuación</em>

Explanation:

Hay una pequeña diferencia conceptual entre la capacidad y el volumen de un objeto, a saber:

El volumen hace referencia al espacio que ocupa un objeto, mientras que la capacidad hace referencia al espacio que este contiene. Calcular el volumen de un cuerpo es medir cuánto ocupa mientras que calcular su capacidad es medir cuánto cabe en él.

En la práctica, ambos conceptos son usados indistintamente, ya que tienen unidades equivalentes.

El volumen tiene unidades de longitud al cubo, como por ejemplo:

m^3,\ cm^3\ ,dm^3,\ pie^3\ , pulg^3

y la capacidad se suele expresar en litros o unidades derivadas: litro, mililitro, centilitro, etc.

Como mencionamos, hay equivalencia engre los dos grupos de unidades. Entre las más conocidas están:

1\ lt=1\ dm^3,\ 1\ m^3=1000\ lt
