So for D you have to find energy right
from c you get wavelength Lambda
so on D use this
E = Hc / lambda
c is given 1.5 x 10 ^20
h = 6.624 x 10^-34
and then you get answer for energy
Answer:
when you put the marker in the water the water gets into the marker and it will change the solid color to a plain color witch means that the marker will make the water in the cup the color from the marker.
Hope I can help
Answer: 2.74 litres
Explanation:
Given that,
Original pressure of balloon (P1) = 100.0 kPa
Original volume of balloon (V1) = 2.29 litres
New pressure of balloon (P2) = 83.5 kPa
New volume of balloon (V2) = ?
Since pressure and volume are given while temperature is held constant, apply the formula for Boyle's law
P1V1 = P2V2
100 kPa x 2.29 L = 83.5 kPa x V2
229 kPa•L = 83.5 kPa•V2
Divide both sides by 83.5 kPa
229 kPa•L/83.5 kPa = 83.5 kPa•V2/ 83.5 kPa
2.74 L = V2
Thus, the new volume of the balloon is 2.74 litres
energy is completely different from energy conservation. Energy conservation means saving energy through such things as insulating your home or using public transportation; generally it saves you money and helps the planet. The conservation of energy has nothing to do with saving energy: it's all about where energy
