Explanation:
Given that,
Diameter of the wheel, d = 70 cm = 0.7 m
Initial angular speed, 
Final angular speed, 
Time, t = 4 s
(a) Angular acceleration,
(b) Tangential acceleration is :
Angular speed of the wheel after 2 seconds is :
Radial acceleration will be :
Hence, this is the required solution.
I believe the answer would be "Different Colors," hope this helps :)
They will both hit the ground at the same time because gravitational acceleration for all objects is the same.
Answer:
one of the reasons is that it wets the glass thermometer it also doesn't detect slight changes in temperature of the atmosphere it has a high boiling point I don't know the rest
