How is precipitation related to high and low pressure air?
Ymorist [56]
A pressure system is a relative peak or lull in the sea level pressure distribution. The surface pressure at sea level varies minimally, with the lowest value measured 87 kilopascals (26 inHg) and the highest recorded 108.57 kilopascals (32.06 inHg). High- and low-pressure systems evolve due to interactions of temperature differentials in the atmosphere, temperature differences between the atmosphere and water within oceans and lakes, the influence of upper-level disturbances jargon as well as the amount of solar heating or radiational cooling an area receives. Pressure systems cause weather experienced locally. Low-pressure systems are associated with clouds and precipitation that minimize temperature changes through the day, whereas high-pressure systems normally associated with dry weather and mostly clear skies with larger diurnal temperature changes due to greater radiation at night and greater sunshine during the day. Pressure systems are analyzed by those in the field of meteorology within surface weather maps.

Suppose that the Millennium Falcon orbits the Death Star 20,000m above the Star’s surface. Calculate the circular orbit velocity
Nataly [62]

Answer:

18.4 m/s

Explanation:

The gravitational force between the Death Star and the Millenium Falcon is equal to the centripetal force that keeps the Millenium Falcon in circular orbit:

G\frac{Mm}{(R+h)^2}=m\frac{v^2}{R+h}

where

G=6.67\cdot 10^{-11} m^3 kg^{-1} s^{-2} is the gravitational constant

M=5.1\cdot 10^{17} kg is the mass of the planet

m=1.36\cdot 10^6 kg is the mass of the Millennium Falcon

v is the orbital velocity of the Millennium Falcon

R=\frac{160,000 m}{2}=80,000 m is the radius of the Death Star

h=20,000 m is the altitude of the Millennium Falcon above the planet's surface

Solving the equation for v, we find the orbital velocity:

v=\sqrt{\frac{GM}{R+h}}=\sqrt{\frac{(6.67\cdot 10^{-11})(5.1\cdot 10^{17} kg)}{80,000 m+20,000 m}}=18.4 m/s

What is the current widely accepted theory about global climate change and what are some predictions associated with it?
Travka [436]
<span>The theory concerning global climate change is that carbon and oxygen are combining to form co2 causing global climate change. Predictions are that they will be positive and negative effects, positive effects are they produce more crops and cold related deaths. Some negatives are damage to crops, rising of sea level, spread of disease and other things.</span>

If it takes a P wave five minutes to travel from the epicenter to a seismic station, approximately how long will it take an S wa
jok3333 [9.3K]

It take approximately 9 minutes for an S wave to travel that same distance that P wave travel in 5 minutes.

<h3>What is P wave?</h3>

P waves, are the first waves to arrive at a seismograph.

<h3>What is S wave?</h3>

An S wave, or shear wave, is a seismic body wave that shakes the ground back and forth perpendicular to the direction the wave is moving.

S-wave is about 1.73 times slower than the P-wave.

A huge, jagged rock sits atop a windy cliffside. Over a period of many years, how will the rock MOST LIKELY change?
sweet-ann [11.9K]

Answer:

Option (D)

Explanation:

Wind erosion will take place extensively as the cliff-side is exposed on the outcrop. Due to the wind erosion, the large, jagged rock will undergo the process of weathering where the softer parts of the rock will be eroded much rapidly in comparison to the harder parts, as a result of which the overall size of the rock will decrease and the surface will be uneven and somewhat rough. This will take place over a due course of time. The main agent that is responsible for erosion is the wind.

Thus, the given rock will become smaller and less smooth after a definite period of time.

Thus, the correct answer is option (D).
