8 0

Answer:

Explanation:

pressure of dry nitrogen gas at 20° = Partial pressure of nitrogen and partial pressure of water at that temperature .

The pressure of dry nitrogen gas= total pressure - vapour pressure of water at 20°C

= 200 k Pa - 2.34 k Pa

= 197.66 kPa.

Which type of nuclear decay is the radioactive isotope fe2659 likely to undergo?
jekas [21]

Beta minus decay will be obtain in the radio-active isotope of Fe-26 power 59.

Whenever there are too many protons or even neutrons in a nucleus, one of the protons and neutrons will turn into the other, which is known as beta decay. During beta minus decay, a neutron transforms into a proton, electron, as well as antineutrino.

Fe_{26} ^{59} → Co_{27} ^{59} +\beta_{1}  ^{0}

It can be seen that after the beta minus decay Fe changes into Co.

In beta decay , decrease in atomic number by one unit Fe atom get converted into Co atom.

Neutron-rich nuclei often decay by producing both an electron and an antineutrino.

Therefore, Beta minus decay will be obtain in the radio-active isotope of Fe-26 power 59.

Please help this is so hard 1: Why is the sky blue?
kolezko [41]

Answer:

1. As white light passes through our atmosphere, tiny air molecules cause it to 'scatter'. Therefore, blue light is scattered more than red light and the sky appears blue during the day.

2. We can see the moon during the day for the same reason we see the moon at night. The surface of the moon is reflecting the sun's light into our eyes. When we see the moon during the day it's because the moon is in the right spot in the sky and it's reflecting enough light to be as bright, or brighter, than the sky.

3. At eight pounds per gallon, that's another 38,593,169,564 pounds of water in the air. Add it all up, and the total weight of our sky is 12,107,415,382,493,169,564 pounds, more than 12 quintillion pounds!

4. 5.972 × 10^24 kg

5. Four forces keep an airplane in the sky. They are lift, weight, thrust and drag. Lift pushes the airplane up.

6. Water is wet, in the sense of being a liquid which flows easily, because its viscosity is low, which is because its molecules are rather loosely joined together.

7. Rainbows are formed when sunlight is scattered from raindrops into the eyes of an observer. The lower the sun in the sky the more of an arc of a rainbow the viewer will see. Rain, fog or some other source of water droplets must be in front of the viewer.

8. Birds can sit on power lines and not get electric shocks because the electricity is always looking for a way to get to the ground. The birds are not touching the ground or anything in contact with the ground, so the electricity will stay in the power line.
