Answer:

Mt. Everest is 3.79 miles high.

Solution:

Everest is 20,028 ft high.

As given, 1 mile = 5280 ft

So $1 \mathrm{ft}=\left(\frac{1}{5280}\right) \mathrm{mile}$

Then 20,028 ft will be $=20028 \times\left(\frac{1}{5280}\right) \text { mile }=\left(\frac{20028}{5280}\right) \text { mile }$

$=\left(\frac{10014}{2640}\right) \text { mile }=\frac{5007}{1320} \text { mile }=3.79 \text { mile }$

The height of Everest is 3.79 miles .

Note: The actual height of Mt. everest is 5.4979 miles or 29029 ft.

If the nails dimensions were expressed in meters, we would have to divide it by 100.

In earlier times there were 3 main types of measurement systems:

1.The CGS system(centimetre, gram and second)

2.• The FPS system( foot, pound and second)

3.• The MKS system(metre, kilogram and second)

But in the present day, we use Système Internationale d’ Unites (French for International System of Units), abbreviated as SI.

The SI Unit of length is meter, but in many cases the length is given in centimeters.

So, we have to convert the value given in centimeter to meter by using the conversion factor which is,

1 meter = 100 centimeters

1 cm = 1/100 meter

Therefore, if the nails dimensions were expressed in meters, we would have to divide it by 100.

How much heat is lost by 2.0 grams of water if the temperature drops from 31 °C to 29 °C? The specific heat of water is 4.184 J/

Elanso [62]

Given :

Mass of water, m = 2 grams.

The temperature of water drops from 31 °C to 29 °C .

The specific heat of water is 4.184 J/(g • °C).

To Find :

Amount of heat lost in this process.

Solution :

We know, heat lost is given by :

$Heat\ lost,H = ms( T_f - T_i)\\\\H = 2\times 4.184 \times ( 31 - 29 )\ J\\\\H = 16.736\ J$

Therefore, amount of heat lost in this process is 16.736 J.

Ratling [72]

Fusion is the energy source of stars. The energy that is being released from the gas collapse into a protostar causes the center of the protostar to become extremely hot. Once the core is hot enough, nuclear fusion commences. The fusion reaction is a very structured process, releasing a huge amount of energy.

This diagram shows that Al can see the reflections of Ed and Fred in the mirror. Which two students can both see the reflections

vazorg [7]

Answer:

Cy and Di

Explanation:

We cannot tell exactly where the right end of the mirror is, but if we assume it is short of allowing Ed and Fred to see each other, we have the following:

Cy can see Cy and everyone to the right

Fred can see Di and everyone to the left

The only two that can see all of Cy, Di, Ed, and Fred are Cy and Di.

_____

If the mirror extends far enough to the right for Ed to see Fred, then all of Cy, Di, and Ed can see the four folks of interest.

horrorfan [7]

Alright I'm not an expert on this, so you'll probably have to verify it with someone more qualified, but here's my idea (the summary is underlined at the bottom, but I added an explanation just because):
Humans are increasing the CO2 levels in our atmosphere, trapping a lot of the sun's heat in. Increased heat increases the chance of desertification and drought, and also causes regional temperatures to go up. The sun's rays are also hitting the icecaps, but the ice itself reflects most of the sun. However, the ocean absorbs the heat, causing the water around the ice to become warmer, just enough to cause them to melt a bit. This melting makes the ocean level rise. So to wrap up, humans are changing the biosphere causing the Earth to warm up, the icecaps and glaciers to melt, regional temperatures to increase, and the chance of desertification to also increase.
It took me FOREVER to write and word this well so I hope this helps. =)
