This is a statement not a question .
Answer:
30 degrees Celsius
Explanation:
With unsaturated adiabatic lapse rate water vapour does not have to change state from gaseous to liquid.
Mechanical Energy transforms into Thermal due to the moving parts rubbing on eachother creating heat and friction.
Answer:
a = 0.1 s b. 10 s
Explanation:
Given that,
The frequency in circular motion, f = 10 Hz
(a) Let T is the period of itsrotation. We know that,
T = 1/f
So,
T = 1/10
= 0.1 s
(b) Frequency is number of rotations per unit time. So,

Hence, this is the required solution.
