If you were on the open ocean on a large ship, what steps would you do to determine the height of a wave?

1 answer:

3 0

The first step to take is to check the anemometer to determine the intensity of the wind blowing in the open ocean. The measurement is in terms of knots or nautical miles. Next, we use a Beaufort scale to check what range the knots falls in. Using the scale, we can see what is the height of the wave. The Beaufort scale is used in open oceans only

Astronomers have observed a small, massive object at the center of our Milky Way Galaxy. A ring of material orbits this massive

Burka [1]

Answer:

$1.91773\times 10^{37}\ kg$

Explanation:

v = Orbital speed = 130 km/s

d = Diameter = 16 ly

r = Radius = $\dfrac{d}{2}=\dfrac{16}{2}=8\ ly$

G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²

$1\ ly=9.461\times 10^{15}\ m$

As the centripetal force balances the gravitational energy we have the following relation

$\dfrac{GMm}{r^2}=\dfrac{mv^2}{r}\\\Rightarrow M=\dfrac{v^2r}{G}\\\Rightarrow M=\dfrac{130000^2\times 8\times 9.461\times 10^{15}}{6.67\times 10^{-11}}\\\Rightarrow M=1.91773\times 10^{37}\ kg$

Mass of the the massive object at the center of the Milky Way galaxy is $1.91773\times 10^{37}\ kg$

Which can be replenished?

Varvara68 [4.7K]

Answer: B.

Explanation:

A replenishable resource is the one which can be produced by natural cycle and can be reused. Such a resource is called renewable resource. The renewable resource can be renewed with due course of time.

Option B is the correct option as it includes the forest. The forest when clear cut for wood or any other need can be grown again by using seeds of the same kind of plants used to grow earlier or by planting plantlets so as to restore the forest again. It is an example of replenishable renewable resource.
