several months after a forest is cut down, a nearby river becomes much muddier than ever before. Infer how the river changed
ryzh [129]
Well this is just my opinion but I think because all the plants were gone they cant stop mud from rolling into it. Also when it rains the trees wont suck up the water, that will make it over flow and release into the land or dirt on the outsides of it. Mixing those two gives mud and it can potentially flow back in the river in largeish masses causing the river to mix with the mud makinging it more muddy. Hope this helps :D

four cars are required to take a group of 16 students on a trip.If there are 36 students to transport how many cars would be nee
Luden [163]

4 cars = 16 students

? cars = 36 students

let x be the number of cars for 36 students

4 • 36 = 16 • x

144 = 16x

144/16 = x

9 = x

It requires 9 cars for 36 students.

//Hope it helps

Pwease hlp me (>O<) Darkness falls during daytime hours. Which event might have occurred?
Tcecarenko [31]

Answer:

D. Solar Eclipse

Explanation:

This is quite a phenomenal occurrence. Please, allow me to explain why D is correct.

A. A New Moon: This is the moon's first lunar phase. This is such a phase during which the sun and earth are located at nearly precise opposite ends of the moon, an occurrence that renders the moon nearly (if not) entirely invisible by the naked eye from an earthly perspective. This is not an occurrence that renders darkness during daylight.

B & C: (Partial & Total) Lunar Eclipse: A Lunar Eclipse is a beautiful occurrence that is visible <em>only </em>during nightfall, but can be witnessed from any location on earth that is <em>currently facing away from the sun </em>(a.k.a. nighttime hours). This occurs when the earth, sun, and moon are nearly perfectly aligned, with the sun and moon at opposite ends of the earth. The earth blocks the light of the sun, and though the side <em>facing </em>the sun won't experience any difference, the side <em>facing away from the sun </em>will be able to see the light from the sun beam around the earth, hitting the moon and reflecting back on us. The shadow of the earth entirely covers the moon during this event. The phases determines exactly what we see and to what degree/extent. This eclipse itself can happen numerous times a year, though only in Partial or Penumbral phases.

D. A Solar Eclipse: A solar eclipse is a breathtaking and oftentimes somewhat terrifying occurrence during which the moon passes <em>perfectly </em>in between the earth and the sun. Unlike a New Moon, however, this occurrence is perceived <em>during the day</em>, so for the side of the earth FACING the sun. When the moon is making its journey in between the sun and earth (which takes roughly 3-5m), the massive silhouette of the moon can be seen blotting out the sun, effectively causing a brief moment of darkness during daytime hours. This occurence is considered remarkably rare because DESPITE it occuring once per year, it can ONLY be viewed from specific locations on earth.

Answer:

1)   Acids have a sour taste.

Acid formulas start with "H", contain hydrogen and some react with active metals in a single replacement reaction to give off hydrogen gas.

An acid will turn blue litmus paper red

All acids are SOLUBLE in water.    

Acids have a pH below 7.

2)     Bases are bitter to taste a bitter taste is characteristic of all bases.

trong bases are very corrosive and can burn the skin.

Bases may or may not be soluble in water Bases that can dissolve in water are called alkalis

They can conduct electricity.

Bases lose their basicity when mixed with acids.

3)    i dont know how to do it on here sorry but its self explanitory!!

A diver, of mass 40kg, climbs up to a diving platform 1.25m high. What’s her KE
Leona [35]

Explanation:

The formula for KE ( Kinetic Energy ) is : 1/2 mv²

Solution:

  • First we solve for v ( velocity ) using the formula 2gh, where g is gravity [ 9.8 m/s² ] and h is height [ 1.25 m ]

= 2 ( 9.8 m/s² × 1.25 m ) = 24.5 m/s

  • The velocity is 24.5 m/s.

  • Now solve for KE using the formula 1/2 mv²

= 1/2 ( 40 kg × 24.5m/s ² )

= 1/2 ( 40 kg × 600.25 )

= 1/2 ( 24,010 )

= 12,005 Joules

  • The diver's kinetic energy is 12,005 J.
