The existence of coal beds in Antarctica indicates that the continent once had temperate, rainy climate.

<u>Explanation: </u>

Antarctica continent is found to rich in coal source found at the surface of rocks near coastal regions. The coal are deposited in a layer forming beds of coal in a specific region of Antarctica. So, these coal were found mostly when plants get buried without complete decomposition in them.

Thus, the large amount of coal in a bed form indicates that once Antarctica was filled with plants and other greenery sources. And this can be possible if Antarctica had temperate rainy climate before a long time.

So, those rainy climate which was once present in Antarctica would have led to production of plants which got decomposed and buried in layers due to drastic change in the atmosphere of Antarctica leading to the present form of Antarctica.

the royal Gorge Bridge in Colorado rises 321 m above the Arkansas river. suppose you kick a rock horizontally off the bridge. Th
KengaRu [80]

Answer:

2.48 m/s

Explanation:

We can use the kinematic equation,

s = ut +½at²

Where

s = displacement

u = initial velocity

t = time taken

a = acceleration

Using the equation in vertical direction,

321 = 0×t +½×g×t², u = 0 because initial vertical velocity is 0

We get t = 8.01 s

Using the equation in the horizontal direction,

52 = u×8.01 +½×0×(8.01)²,. a = 0 because no unbalanced force act on object in that direction

So u = 2.48 m/s

What is the gauge pressure in Pascals inside a honey droplet of a 0.1 cm diameter? Assume that air is surrounding this droplet a
Vikki [24]

Answer:

The gauge pressure in Pascals inside a honey droplet is 416 Pa

Explanation:

Given;

diameter of the honey droplet, D = 0.1 cm

radius of the honey droplet, R = 0.05 cm = 0.0005 m

surface tension of honey, γ = 0.052 N/m

Apply Laplace's law for a spherical membrane with two surfaces

Gauge pressure =  P₁ - P₀ = 2 (2γ / r)

Where;

P₀ is the atmospheric pressure

Gauge pressure = 4γ / r

Gauge pressure = 4 (0.052) / (0.0005)

Gauge pressure = 416 Pa

Therefore, the gauge pressure in Pascals inside a honey droplet is 416 Pa
