Answer:
Explanation:
Here by ideal gas equation we can say
now we know that pressure is kept constant here
so we will have
since we know that number of moles and pressure is constant here
so we have
now we know that initial temperature is 17.8 degree C
and finally volume is doubled
So we have
so final temperature will be
<span>d. The parallaxes beyond a few thousand light years are
too small to be measured with common instruments.
I'm not sure that parallax can even be used out to a few
thousand light years.
The NEAREST star to Earth has the BIGGEST parallax.
The star is Alpha Centauri. It's only 4 light years away
from us, and its parallax is 0.000206 of a degree !
I have no idea how astronomers can measure angles
so small ... and that's the BIGGEST parallax angle of
ANY star.</span>
Answer:22.6g
Explanation:
Mass of water(mw)=1liter=1000g
Final temperature=20°C
Temperature of ice=0°C
Temperature of water=56°C
Change in temperature of water=56-20=36
change in temperature of ice=20-0=20
Specific heat of water=1cal/g°C
Latent heat of ice=79.7cal/g
1000x1x36=mx79.7x20
36000=1594xm
Divide both sides by 1594
36000 ➗ 1594=1594xm ➗ 1594
22.6=m of ice
m of ice=22.6g
Infrared light has longer wavelengths than gamma rays, X-rays, ultraviolet light, and visible light, but shorter wavelengths than microwaves, radar, GPS, cellphone, TV, radio, ocean, audible sound, ultrasound, seismic, guitar-string, and Slinky™ waves.
