Please help with question 1 - 4. Thank you

1. Calculate the numerical value of the saturated pseudoadiabatic lapse
rate in °C km-¹ for p = 300 mb, T = -20° C.
2. A thick atmospheric layer is isothermal with temperature -3° C. A dry
parcel is given an upward impetus and begins to oscillate about its original
position. Calculate the period in seconds of the oscillation.
3. For the situation given in Problem 2 above, suppose the initial impetus
is enough to cause the parcel to rise 1 km above its original level before it
begins to sink again. Calculate the energy per unit mass which had to be imparted
to the parcel to produce this displacement.
4. Show that I, ≤ Fa in the meteorological range of temperatures.
