Answer:
Explanation:
Florida is much closer to the sun as compared to New York and seems to be much warmer as compared to New York even in winter and summer because of the latitude.
Answer:
Please take this hepful hint :
F = m * a
6.2 = 2.3 * a
a = 2.7 m/s^2
Explanation:
Answer:
The function of the cathode ray tube is to convert an electrical signal into a visual display. Cathode rays or streams of electron particles are quite easy to produce, electrons orbit every atom and move from atom to atom as an electric current.
There are 1,000 milligrams (mg) in one gram:
In 10 grams, there are 10 x 1,000 = 10,000 milligrams. This is a lethal dose of caffeine.
There are 4.05 mg/oz (milligrams/ounce) of caffeine in the soda.
In a 12 ounce can, there are 4.05 x 12 = 48.6 milligrams.
How many sodas would it take to kill you?
To find this, we divide the lethal dose amount (10,000 mg) by the amount of caffeine per can (48.6 mg).
10,000 ÷ 48.6 = 205.76.
Since 205 cans is not quite 10,000 mg, technically it would take 206 cans of soda to consume a lethal dose of caffeine.
<em>Answer:</em>
- The halogens have electron configurations that end in ns2np5.
<em>Explanation:</em>
<em>Halogen: </em>The elements of group 17 of periodic table are halogens like F, Cl, Br, I etc. They have 7 valence shells electrons. The electronic configurations of each halogen is given as follow
- F = [He]2s∧2 2p∧5
- Cl = [Ne] 3s∧2 3p∧5
- Br = [Ar] 4s∧2 3d∧10 4p∧5
- I = [Kr]5s∧2 4d∧10 5p∧5
From electronic configurations, it is cleared only halogens have valence shell elctrons in ns∧2 np∧5.
<em>Transition elements: </em>In transitions elements , electronic configuration ended in d- orbital.
<em>Inner transition elements:</em> In transitions elements , electronic configuration ended in f- orbital.
<em>Nobel gases</em>: Nobel gases elements have complete valence shells, Eight electrons like this ns2np6.
