es of UV Radiation
Scientists classify UV radiation into three types or
bandsUVA, UVB, and UVC. The ozone layer
absorbs some, but not all, of these types of UV
radiation:
UVA: Wavelength: 315-399 nm. Not absorbed by
the ozone layer.
UVB: Wavelength: 280-314 nm. Mostly absorbed
by the ozone layer, but some does reach the
Earths surface.
UVC: Wavelength: 100-279 nm. Completely
absorbed by the ozone layer and atmosphere.
UVA and UVB radiation that reaches the Earths
surface contributes to the serious health effects
listed above; it also contributes to environmental
impacts. Levels of UVA radiation are more
constant than UVB, reaching the Earths surface
without variations due to the time of day or year.
In addition, UVA radiation is not filtered by glass

Jua lina aina 2 za mizunguko,kwanza kuzunguka jua;mzunguko huu hutupatia misimu minne ya mwaka yaani kiangazi,kipupwe,vuli na masika. Pili,dunia kuzunguka mhimili wake Wenyewe; mzunguko huu utupa zamu ya mchana na usiku,na utofauti wa masaa katika uso wa dunia.

mkuu jua halizunguki, sayari ndio zinazolizunguka jua!

Sasa hapo sayansi ya jua ipo wapi mbona umetoa sifa za kitu

Tunaomba kujua wana sayansi walio enda kupima joto la jua walitumia material gani?, nilijaribu sana kumfatilia Izack Newton mgunduzi wa jua lakini hakuna sehem aloandika kwa uyakinifu vifaa maalumu vilivyo tumika kupima joto la jua!

Never heard before!!!!Newton wa wapi huyo????

Biblia inasema mungu aliumba usiku na mchana sasa tuelewe kipi hapa

wakati Yesu anakufa tunaambia jua lilitiwa giza, yaan lili kata mwanga. hivi pale ilikuwaje kama dunia inalizunguka jua na wakati huo mwelekeo wa dunia uliliangalia jua,sasa nikitu gani labda kilifanyika na giza likaingia?

Na jua nalo linazunguka

""Ndiye anaye pambazua mwangaza wa asubuhi; na ameufanya usiku kwa mapumziko na utulivu, na jua na mwezi kwenda kwa hisabu. Hayo ndiyo makadirio ya Aliye tukuka Mwenye nguvu, Mwenye ujuzi.""

Unapoingiza Yesu,huyo ni neno muumbaji,njia zake hazichunguziki,ni si za wanadamu. Sasa unaweza kusema ni vipi yesu alitembea juu ya maji?

How "Fast" is the Speed of Light?
Light travels at a constant, finite speed of
186,000 mi/sec. A traveler, moving at the speed
of light, would circum-navigate the equator
approximately 7.5 times in one second. By
comparison, a traveler in a jet aircraft, moving at
a ground speed of 500 mph, would cross the
continental U.S. once in 4 hours.

500mph ? What do you mean sir

Miles per hour

Ok . I wondered how fast was an object to cross the us continent
Within 4hr because the speed was too little

Can you tell a fastest object eve made by human being

At 3:21 p.m. (EDT), NASA'S Juno Mission spacecraft will slingshot around
Earth towards Jupiter, accelerating to 25 miles per second along the way
and becoming the fastest man-made object in history. A .50-caliber bullet
travels at about half a mile a second, by contrast -- nowhere near the
blistering speed of Juno.

Haiwezekani, lazima nishangae... Nje tu ya dunia hapo karibu radiations zinapiga ile mbaya.. mtu akaribie jua hajisomi?? hamna material yoyote ile duniani inayoweza stand joto la jua

Nasa wameshazoea kutudanganya sana, usikute kuna sehemu hawajawahi kufika ila wanatuletea picha kuwa wamefika

Je jua linazunguka au limetulia?

Jua linazunguka,physics ya A level inasema.na hasa rotation,ingawa bado haijulikani revolution yake ikoje.

hii ni hadithi¡-¡- science without source of data is meanless

Hawadanganyi, ni wewe tu ndo huna uaminifu kwenye science.. Agency kama ile hua hawafanyi mambo kiholela! ndo maana wanachukua only the best minds in the world... sio majini wale jamaa, ni binadamu ka wengine hawana sababu za kudanganya dunia nzima wakatupa picha feki
