Answer:

12.3 seconds

Explanation:

time in air = 2(v)/g

2(100sin(37))/9.8

=12.28 seconds

Vertical distance h isΔg=\frac{-2GM}{ RE^{3} }

<h3>What is vertical?</h3>
  • The distance between two vertical places is known as the vertical separation or vertical distance. There are numerous ways to express vertical position using vertical coordinates, including depth, height, altitude, elevation, etc.
  • The formula for vertical distance from the ground is y = - g * t2 / 2, where g is the acceleration of gravity and h is a height.
  • The vertical distance between the measurement point and the point of observation on Earth's surface. Altitude is the vertical distance from the measurement place to mean sea level.

Assuming h is small in comparison to the radius of the Earth, show that the difference in free-fall acceleration between two points separated by vertical distance h isΔg = (2GMeH) / RE³:

Given:

Separated between two points=h

And, h∠∠R_{E}           (R_{E}= radius of the Earth)

Now, \frac{dg}{dr} =\frac{-2GM}{ RE^{3} }

dg =\frac{-2GM}{ RE^{3} } dr

Δg=\frac{-2GM}{ RE^{3} }  

Therefore, Vertical distance h isΔg=\frac{-2GM}{ RE^{3} }

Increasing the concentration of greenhouse gases in Earth's atmosphere decreases the transparency of the atmosphere to infrared
kondaur [170]

Answer:

Decreases the transparency of the atmosphere to infrared light.

Explanation:

When a large amount of green-house gases are present in the atmosphere, the layer of these gases become opaque to infrared radiation and radiation from the sun get trapped into these gases molecules. These excited molecules radiate this energy into our own atmosphere and that why the temperature of Earth is rising due to the Green-House effect.

marta [7]

Of the following given choices;

A. A higher fertility rate

B. Less access to medicine

C. A new source of fresh water

D. A higher birthrate

The answer is; C

Carrying capacity is the maximum population size than habitat or environment can sustain indefinitely because it is able to replenish its resources. Limiting factors to carrying capacity of an ecosystem include resources such as food, water, and space.
