For this question we can use the combined gas law equation.
for a fixed amount of gas
where P - pressure , V - volume , T- temperature and k - constant
Where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
temperature in K
T1 = 12 °C + 273 = 285 K
T2 - 16 °C + 273 = 289 K
substituting the values in the equation
V = 1.00 mL

Answer:
Part a)
Part b)
Explanation:
Part a)
change in the energy due to decay of photon is given as
here we know that
now we have
Part b)
While electron return to its ground state it will emit a photon of energy 2/3rd of the total energy
so we have
now to find the wavelength we have
Answer:
last answer
Explanation:
gripping it with the blade facing downward is the most efficient and safe way to use an exacto knife
After 1 second, the dropped ball has fallen:
s = ut + 1/2 gt^2
s = 0 + 1/2 (-10) 1^2
s = - 5 m from starting point
After 1 second, the thrown ball has risen:
s = ut + 1/2 gt^2
s = 20 (1) + 1/2 (-10) 1^2
s = 20 -5 m
s = + 15 m from starting point
The two balls meet one second after release and meet at a point 15 meters above ground.
