Explanation:
When we have to convert temperature from degree celsius to kelvin then we add 273 into the given degree celsius temperature.
Therefore, convert into kelvin as follows.
Temperature in kelvin = Temperature in degree celsius + 273
= (32.5 + 273) K
= 305.5 K
Thus, we can conclude that temperature in kelvins is 305.5 K.

Explanation:
It is given that,
Mass of the rim of wheel, m₁ = 7 kg
Mass of one spoke, m₂ = 1.2 kg
Diameter of the wagon, d = 0.5 m
Radius of the wagon, r = 0.25 m
Let I is the the moment of inertia of the wagon wheel for rotation about its axis.
We know that the moment of inertia of the ring is given by :
The moment of inertia of the rod about one end is given by :
l = r
For 6 spokes,
So, the net moment of inertia of the wagon is :
So, the moment of inertia of the wagon wheel for rotation about its axis is . Hence, this is the required solution.
